T case leak

19 w/ 50k miles. Noticed it leaking where the t case meets the trans. It hasn’t started leaving a puddle on the driveway , but there’s definitely oil there. I’ve read other posts about dealers not doing anything about it til it actually “leaks” which I find complete bs and I hate dealing with dealers already. Has anyone had the same problem and fixed/had it fixed? If so, what was the issue? Is there a seal that keeps the gear oil in the t case where it meets up to the back of the trans ?

 

Give everything a good wipe down with Simple Green or carburetor cleaner and observe.
Wouldn't be a bad idea to check all your fluid levels too.

 

looks more like a leak than a weep

 

Pretty normal if you wheel it, since you are constantly trying to twist all the mating surfaces. I just completely resealed mine at 60k since it was leaking from pretty much every joint, and used the right stuff rtv instead of the red stuff toyota uses.

 

Where did you reseal it at? Is there a pressed in seal where it mates up to the trans

 

Took it to dealer, tech says it’s trans fluid. I spoke with him over phone, he’s swearing up and down the t case seal is dry but the fluid is leaking from trans seal. That’s some strange looking atf to me

 

Are they gonna do
Something about it?

 

Most dealer will not deal with it becuase its seeping. Toyota definition of leaking is...

They’re replacing the trans seal. But like I said, I swear that’s gear oil. Never seen any trans fluid looking like that before , ever.

 

Theres no hiding the smell of gear oil.

 

Auto WS is red-ish. Is this a manual?

 

Nope. It’s auto

 

I just looked at it in person. The front of the t case is dry. Sure nuff it’s the rear output trans seal. Will be covered under warranty.

 

Someone correct me if I’m wrong but AT fluid is pink?

 

It definitely is. It’s really hard to describe and it’s really weird to see but it’s def trans fluid. It looks gold til u get close to it and put a light on it. Front of t case is dry.

 

Yea I should’ve smelt it… dammit

 

You are not the first person it has happened to.

Even some of us 2nd Gen guys have had the output seal leak on us.

As soon as you said trans meets the transfer case, I was going to ask “are you sure it’s not ATF?”

Good to hear the dealer is going to make it right.

 

Hope it doesn’t happen again for awhile. Trucks only 3 years old with 50k miles. Geuss I’ll be doing it myself next time it happens. Only 10k left on the power train warranty

 

It probably won’t, things happen. I think it will be fine for a long time.
Some times I think installation is the cause, other times it’s just a bad seal.
