Toyota Transaxle Fluid Level Check – No Dipstick


Hello my name is John Kelly and this is
the WeberAuto YouTube channel today we’re going to talk about how to
check fluid level on Toyota automatic transmissions that
do not have a dipstick now every one of my students that I even
bring this topic up with roll their eyes and think oh my gosh
everybody knows how to check transmission fluid you don’t need to tell me how to do that
well, come to find out the very few people actually know how to
check the fluid level on a Toyota transmission without a
dipstick and there are other vehicle manufactures
the don’t have a dip stick or a dipstick tube just like the Toyotas, the the Aisin
automatic transmissions, and so I want to show you the proper
method of checking the fluid level, it’s very
involved there’s a twelve-page document just to do it out of Toyota service information for
several of their automatic transmissions, and so what I
have here is the oil pan from an Aisin U660E or U760E or F transmission. This is the
six-speed automatic transmission that comes just about every front wheel drive Toyota mid-size,
full-size, car it has no dipstick tube, no dipstick, instead, what it has is this little straw and one drain plug in the bottom pan now this drain plug is is both a drain plug to get fluid out of
the transaxle its also a plug that we use to check the
fluid level and so we’ll take a, just give you a quick demonstration
in the parts, you will need a a 6 millimeter hex drive to remove the the drain plug and when you get that plug out there is
still this red straw sticking up
so let me zoom in so you can see real close what i’m talking about here this straw, that sets the fluid
level, at the top of that straw and so if you
pull the drain plug out, take the drain plug out, and fluid comes out of that straw you might think that “Oh, was over
full” and you’re supposed to let it but continue
draining until it reaches a slow drip and then put the
plug back in and “shazam” you are all done A lot of my students and other
people that I talk to think that that’s all there is to it but, there’s a big problem with that in this this transaxle is very picky about
its fluid level being correct it’ll make all kinds a noise that
actually sounds like a power steering pump hydraulic power steering pump although
this has electric power steering it is that’s the kinda whining cavitation type of noise that you would
hear wel,l the as it turns out the fluid that is used in Toyota transmissions the world standard, the WS fluid here,
like almost any other transmission fluid
expands when he gets hot and if you actually went into Toyota’s
service information and printed the instructions on how to
check this fluid level “you need instructions check fluid
level everybody knows ever do that” if you actually checked the the
instructions it would tell you that this is only
going to be accurate between 104 degrees in 113 degrees of automatic transmission fluid temperature now what temperature is fluid normally? lets say a customer has been out
driving around and they decide “oh hey, I need to get my oil changed and i’ll pull it into some oil change place,
or even the Toyota dealer or any other repair shop to get my
oil changed, and have them check all my other fluids too” If somebody even attempts to check this fluid level chances are they’re
going to let too much fluid out because they’re checking it when
the fluid temperature is too hot this fluid expands, all transmission fluids
expand, but if you check this fluid when the
temperature the fluid is above 113 degrees Fahrenheit the fluid has expanded, the volume is
physically increased from expansion and if you pull that, this plug, out of the
bottom of the transaxle and wait for the fluid to finish draining,
you have just effectively drained fluid out of a transaxle that was probably filled correctly out of the factory.
so the 2007 and above front wheel drive Toyota vehicles that
use this transaxle the only way you can accurately check
this on the customer whose transmission fluid temperature was above
a 113 Fahrenheit was to make him leave the car, and if the the transaxle was all the way up to
normal operating temperature or at least 185 degrees to his as high as maybe 220, 230 degrees
Fahrenheit it is way to hot to check, so you may even
have to keep the vehicle vehicle overnight just to let the fluid
cool down and you can not, as part of a lube oil and filter, tell somebody that
you checked the fluid level if you didn’t check it, or if you didn’t
check it accurately, you need to do it the right way, now this has caused a lot of these
automatic transmissions to be under filled and when they’re under filled they starve
for fluid, clutches can slip from lack of fluid
pressure, and burn the transmissions up, transaxles up. So Toyota last year, within the last year, year and a half or
so, came up with a new procedure to adjust this fluid level, and so the printed service information that they have online is the information on how to check
this fluid level when it’s between 104 and 113 degrees; it still
works great and you don’t need any special tools to
check that if you have a vehicle that is at that
temperature, and of course how do you check the fluid level? you have got to have a scan tool the plug
into the data link connector and pull up the transaxle
transmission fluid temperature sensor well unfortunately or fortunately most
vehicles when they come into shop are going to be warmed up more than 113
degrees so Toyota has released a Technical Service
Bulletin talking about, and telling you about, some new tools that are available to
allow you to check this transmission fluid level at a hotter temperature and I want to
show you these these tools so just to check transmission fluid
level on a on a Toyota Camry Highlander Venza, Sienna just about any front wheel drive
six-speed automatic transmission you’re going to need this big pump
assembly back here full of world standard fluid and this pump just has a quick connect
fitting here that allows you to connect right to the fill plug, the fill port, on
the automatic transmission and pump fluid right into it, and I will show
that on the car then you are also going to need this vacuum tank or some other type
vacuum system to put a vacuum on the
transaxle so that when you pull this plug right here when you take this plug out
if you reply to vacuum to the transaxle fluid will not come out, you won’t lose
your fluid so you put a vacuum on the fill plug up the transactional with this the air powered vacuum here and then there’s this kit right here, so we need these three pieces
to check fluid level, this kit has a vacuum regulator to make
sure we got enough vacuum to pull the plug we have an adapter to connect to the
transaxle, and then we have very interesting little tool right here
that I want to show you on the oil pan, so obviously I have told you that the transmission fluid level increases as it gets hot, the volume, the fluid
expands, the volume increases, and so what Toyota has done, has come up with a, they’ve come up with the tool that when we take this drain plug out at the bottom of the transaxle,
which by the way you it won’t drain the fluid out, it is just to check the fluid
level, if you want to take the fluid out you’ve got to take the straw out and it
uses the same 6mm head driver and you you just run it to all the way
through the bottom the transaxle and take it out and now you can drain the fluid out
of the transaxle, but we need this in there to check the fluid level at 104 degrees, 104 to 113 that’s the only reason that piece is there.
Alright so let me screw up back in, alright what this tool does from this kit, is it gives us an adjustable height straw, so this red straw only comes in
one height this has a tube that good can go up and down, so let me zoom in on the tool
here so you’ll notice that it has some
graduations in millimeters, every, well it has one millimeter markings; we start at 0 and it goes as high as 150 millimeters here, and in the technical service bulletin you
have to look up your year, make, model, and drive of vehicle and
it will tell you how many millimeters to stick this to up. Now this Venza we’re
going to work on is 71 millimeters so here’s the seventy right here there’s
the 71 there’s little thumb screw on the back right here, i am just going to lock that in place and that will, when we put this tool in our drain plug hole and stick it in, and we just tightening up by hand, notice now… get it to focus, there we go, that tube as part of the tool sticks up higher and
that is because this tools designed to check the fluid when it’s at 185 degrees or higher and so I’m sure there’s a maximum temperature
that it’s rated for but if I loosen this thumb screw
down below I can shorten the height that straw I can lengthen the height that straw,
that allows us to compensate for the fluid expansion in this transaxle, so we are going to
go over to the vehicle and actually do this entire procedure
and check the transaxle fluid level on this the 2009 Toyota Venza that has this the transaxle in that I just happen
have in the shop today as part of my
transmission class so let’s go over to the vehicle and I’ll
show you how all this works and check the fluid. Okay we are over to the
vehicle in like I said we have got a 2009 Toyota
Venza all-wheel-drive vehicle on the hoist and first thing I want to show you is
the scan tool so lets zoom in and take a look at some
data values that we need for this exercise the first thing we need is our
transmission fluid temperature so our automatic transmission temperature, oil temperature, as you can see there is 186 degrees so 185 is the minimum that the Technical Service Bulletin tells us
so 185 to 194 is the preferred temperature. I’ve let this
thing run for hours and hours and hours and it
never exceeds 194 at an idle so in your shop just sitting there idling once it gets up property temperature here
you should be fine the other piece of data that we need is
right here, that’s our engine speed 670-680 690, so less than 700 rpm so we’re looking at transmission fluid
temperature and engine RPM on the data list for the automatic
transmission alright, the next thing I want to show you
is right here in the left front wheel
well if we zoom in behind the tire and we had to take a little plastic
panel off right there that plug with the letters WS which
stands for World Standard that plug is the transaxle oil fill
plug that’s where we’re going to put in fluid as we check the automatic
transmission fluid level and so we need to take that plug out and we will install an adapter from the fluid level checking kit so let me get that adapter and whoop will get that installed so the
adapter calls for is this one with the green 15 and I’ve already loose another or oil
fill plug so I’m just going to reach up in there
its pretty hot engine at normal operating
temperature I’m going to take that fill plug out
without burning myself and I will screw in this green adapter in its place and you just
screwed in by hand just hang tight as little ring the does
the ceiling love the mom entrance to the them to the transactional so now we’ve got that perhaps adapter
the connected museum in just a little bit Singh see it little better so now I’ve
got the adapter the green 13 of hooked on the adapter comes down and has a quick connect fitting just
like an air hose right here that we will connect to a vacuum regulator and a vacuum pomp not palm but a a vacuum through with an
air powered vacuum to all so museum out sOooo I can show you the the tools right here I’ve got the vacuum regulator we’re just gonna hook this up underneath
the bottom of the vehicle connect this clear hose to that vacuum
fitting thats um we’ve already installed on the inlet the fill plug to the transmission that the vacuum
regulator I’m just going to Book It here under Needwood the vehicle
somewhere when a good place to to hook it right there and I’m just going to
connect the vacuum regulator to that pipe that
we have connected to the inlet to I’ll the automatic transmission Trenton so now you can see have got the
regulator and has a gauge on it means you can see
the the gauge this just this gates just
majors inches of mercury vacuum in this press week Asian specification
we’re going to be looking for is between to and five inches love mercury so here’s the five
mark right there and zero so somewhere in
this range when we get our vacuum the tank hooked
up okay let me get the vacuum tank this is the vacuum tank grey here and it it has a flexible hose that is going to connect to the bottom
up OVR vacuum regulator your some is going to
connect to that up right there it has on offer well right
here where I can turn the vacuum on or turn it back off and of course there’s
no vacuum on it yet because on this tank there’s and Quick Connect air for a team for our
shop air supply and it should not be any
higher than 100 PSI so we’re gonna okay compressed air
to hear you know flow crossing offers create a vacuum in this tank the report a vacuum on the
entire transact so inside so let me get the heroes now now have our our shop air I’m just going to connect
that to a vacuum tank years and there’s about
right here on the top and we’re just going to turn that on ash K know I know thats noisy may have a hard
time hearing me while much money so let’s take a look at the gage now sure if which again we’re looking for cash who sure-fire refuges the mercury few
looks like word about two-and-a-half three fuses amo three sure we’re right within the
specification when or where we should be kroll we’ve we broke up the vacuum tank we’ve
applied a vacuum to the transactional itself and the fourth bath
is going to allow us to do you bring the camera and even closer now okay every position the camera we’ve got
our and 225 inches of mercury on our vacuum
gauge if you put a vacuum on the transactional and what that is going to allow us to do
now his command right here on the drain plug and remove it and that’ll allow us to
remove it with al losing any fluid normal if you follow
this blog out we’re gonna lose fluid worth them my pre lucinda for this demonstration love you can we get it out for us to the way as long as we’ve got a vacuum on there
we should be OK and not have any fluid murder about and if we did Uploadr about its it’s at a
hundred maybe under 90 degrees and they would burnish 31 were probably worse blows but notice not draw
for food comes out now for turner vacuum of local
definitely you come out so we do not want to do
that also thought of to the side here for the next thing we’re going to do is
get that adjustable straw but I showed you with the graduated markings in millimeters on the
side the instructions tell us to install this to all with the straw all the way down so right here are millimeter markings I haven’t retracted
all the way I’m going to screw that and it’s all the way in them in the server same information the service morton it we have to look up the year make
model this vehicle this particular one tells us that fee
for engine autos between seven for 600 and 700 rpm the charges less than 700 we have just
this to the seventy one millimeter mark her seventy right here so everyone’s up
a little higher so we’re just gonna let this author to new server the 71 and right thumb screw now we have a little holes here the fluid world-renowned old a if its overall but now we’ve
compensated 4 the hot temperature have the fluid now for Sony the drain pan a to capture
the the fluid let me grab that report if it
is overfilled it fluid will come out in there so we
want to make sure that we’ve got something to capture that fluid alright I’ve got a in the brain bucket below here so here’s our holes let me zoom and know but on the whole
Swedish watch it if the fluid was too high too much fluid in when we turn of the
vacuum sure does Amanda shut it off cut it off on the offer vile can turn it off on the
lower valve here comes some fluid so notice it’s not a lot of fluid but we have some fluid coming out there
know what that tells us is that it was not tool all because if
it was too low we wouldn’t have any fluid coming out there at all if it were too high a we would have a
constant stream upload coming out and so what we’re looking for is pretty much
exactly this include is just barely coming out the
kind of a slow drip here then we know that for this transmission
fluid temperature that the um fluid level is correct now
let me show you what would happen here we had didn’t have this tool and we relied on the um the height about red straw inside a the transmission no oil pan so that I’m going to let this level down to these a lower level notice now we have fluid just drain you know they’re like crazy
them and we’re just gonna sit there and rain
and rain and rain fluid and this is where the technician would
think they’re doing a good job may we think all those the transmission
fluid levels to fall what’s not to fall it’s just your check
in at at a hundred maybe six degrees rather than 900 for 213 so we drain fluid outta there the
question now is how do we add it to so let’s compensate for the increased
flow temperature will take this back up to the ones for the seventy one millimeter mark
roommate their K notice now I’m that when we are low on
fluid we’re just barely gettin any drip out on their own all resume and
just a little bit see if we get a better year ago knows it it’s not driven out like it was before so if you see this then you know that
the fluid level is too low and now I need to add fluid so to add
fluid we need the third piece but the special
tool kit the fluid pomp though showed your on the
table earlier slim is amounts you can see this the football okay this fluid pomp tank here infill
followed the proper fluid has a palm panel right near the palms as
you push down and full backup and it has a flexible holes
with the Quick Connect fitting and we’re going to connect that pomp
right here to the same line that we have to back
impromptu before and we’re gonna pump fluid into the transactional in the same hole
that we apply to vacuum so let me disconnect bat and connect up
or holes there we go okay about the pomp connected to the in what did up the transmission and now let’s watch this this hose again and we will pomp fluid into the
transmission until we see fluid come out over this holes here so I’m going to start poppin putting transmission fluid back in poem
slowly as I can from more and here we go so see
now the flutist starting to come out too much fluid I’ve
added but it’s better to have too much than
too little because we can just simply let it drain here until the fluid level is where it should be so will just let
it sit here let it get down to earth just barely a
slow drip getting closer and closer so obviously this is a fluid level check
the you’re not going to be able to do in 20 minutes even five minutes this is not a quick simple easy the service and I recommand that you if you have a customer wants a
transmission fluid level checked or PC Lee can you suspect that it it
needs to be checked that you charge appropriately this is a
big job it used to be done correctly you need to have proper major much need
a proper scan tool to read the the transmission temperature another
vehicle manufactures are very similar I in their fluid level checking
procedure for transmissions that do not have a
dipstick moratorium is the only one that has this
adjustable straw that I’m aware although Ford has one
that you put a vacuum on a.m. put fluid and then undo the vacuum
in as a straw inside the pan that allows the fluid to come out until
reaches a certain level but all these are temperature
dependent right if we look at this drain holes now you can see that we’re back to the slow drip off that’s what we’re looking for is just a
slow drip right there now if we make the mistake just simply were unscrewing this just will straw I’ll to bottom the
transactional all the fluids just gonna come out so we have to put a vacuum back on the
transactional to get it out so I’m going to this
connector pom-pom line here get it out of the way we’re going to
reconnect our vacuum it’s worse turn back on the vacuum sure and when I turn the vacuum I want you to
watch what happens to those dripping fluid here usage trippin becomes the vacuum right there soon as I hit the vacuum it stops
European you for the vacuum on the transactional now now we can unscrew the store you will be
caught so be careful notice we’re not losing any fluid its at all even though we’ve added fluid and now I need to get the heart for the
the drain plug minute ago move with that mackey am K here’s a torque specification I think
it’s 36 foot-pounds feel on this blog and there’s approach first vacation on
the fill plug also now I can turn off its at the turn of the vacuum so we’ve got a
lever right here you will ever down on a the vacuum tank itself alright wealth obviously now we just take off
the the adapters and put the fill plug back
in that is the did most involve transmission fluid level
checking procedure ever seen it involves probably hundreds of dollars
worth of tools when the common questions my students
ask me is how much those tools cost no I really don’t know I’m sure it’s
several hundred dollars to get them all the and they say all our
shop I’ll never buy those well what’s the alternative how else are
you gonna check this fluid in am fluid level and get it at the right
level unless you’ve got a system something like this the like I
said before these transactions are very picky about their um fluid level what do you burn all
transaction your private wrong and somebody who doesn’t even realize
that they’re doing it wrong drains fluid out so it becomes too low and how much does a
transactional cost while I guarantee across a lot more most tools so do yourself a favor get the right
tools for the job or don’t do it at all Norma Toyota on other Toyota vehicles and Lexus vehicles
they still have the littles the not the red straw but they’ve got a
medal to in their pants they don’t have this
temperature compensating tool for those and so those like on the Toyota Tundra
the and it any other vehicle that does not
have a a dipstick it is temperature sensitive n you need
to be aware you need to be checking also blue levels at the proper temperature or you can cause low fluid level and
transmission damage without even realizing that you did well this has been a demonstration of
checking the fluid lorna that Toyota transaction without a
dipstick the three are you sick sixty EU 760 E
and F these two wheel drive s 4-wheel Drive
mmm have a good day
