2017 Low Automatic Transmission Fluid

"Clunk' or harsh downshift. I think mine does the same thing. I think it is fairly common. That is why I am checking my fluid level. That and peace of mind.

I am starting to think it the way they designed the transmission. My fluid is full and still does it when cold. I only have 600 miles on it so I am giving the 2k miles it takes to learn my habits to see what changes.

 

I hear you... Me too, taking my truck to get the transmission fluid levels checked on Tuesday, and hope the dealer do it right...
Cheers..

 

Check back with with the results.

Mike

 

Sure will..

 

If the clunk you’re hearing is there when harsh axle changes occur, check the u-joint on the axle as it may need grease, or be failing. Get low on the side of the truck, looking at the differential and have some one start, put in forward gear (brakes on), neutral, reverse(brakes on) and listen and look for the clunk.

Auto-Transmissions are fluid and should not clunk. There are valves that open/close, which can cause abrupt sensations, but shouldn’t be clunks.

 

Very possible.. But who knows?

 

I can assure you I didn't drain the transmission fluid. Toyota is giving me an 8 yr 125k extended warranty. I am just afraid if my transmission does fail they will make up an excuse to not cover it.

 

Checked my fluid this morning per the procedures in post #18. I first put a quart in and pinned the cooler bypass. I drained out about a quart. Fluid level was fine. Thanks to Splitbolt for the procedures and gearcruncher for the advice.

 

Now you know it's right.....

That was worth the effort wasn't it..?

 

Gave me peace of mind!

 

thats what they do....add but dont tell you and make no notifications on the paperwork....bastards

 

why would they, its only opning a can of worms if they tell u. this way they just say nope everything was good here,

 

dont let them use the tech stream....make them do it manually

 

In for the results . I would like to hear from other 2018 owners .
Let us know if the 18,s are filled to spec or low on fluid
In post 18 , Mr. Splitbolt provided the instructions . Its not hard to check your own fluid .
Do I change the Low fluid poll and add the 2018 Tacoma,s to the list ?
There are now 2 members with 2018 Tacomas who have had low fluid .
Need to hear from other members who own the 18 Taco .
In a small community such as Tacoma World , I beleive 10 trucks low on fluid will be enough of a deciding factor ( baseline ) to comfortably add the 18 to the low fluid poll .

If I don't want to go through the hassle of pinning the obd port and putting the truck into temp check mode - couldn't I just pin the thermostat and monitor the pan temp on the fusion app until it reaches 95*F and check it at the point?

 

This is why we tried to get you guys to watch the technician perfoming the level check .
If you read the low fluid poll , there are some good posts about dealership techs saying one thing , yet doing another hint hint .
Painting the overflow bolt was an excellent idea !!
You can always slide under the truck and have a peek to see if the paint is ripped up . At least you will know for certain the manual fluid level check was done somewhat properly .

Sure !!
There is no reason why you couldnt do the fluid level check this way . Its going to get you very similar results as doing the full procedure .
If you do find the trans low , dont add fluid ...Off to the dealer you go for proper warranty documentation of the issue

 

The last time I wanted them to check it, they said they don't do checks unless there is a failure in some way. Instead, they applied the first tsb.

It have 42k on it now, and it's never really given me problems, but if it IS low then I would like to at least top it off.

 

I followed Mr Splitbolt’s instructions at 92miles on my 2018. It was filled to spec.
