how is it possible for tranny fluid to leak into the transfer case? i changed the fluid in the tranny, t-case and rear diff about 2k miles ago. 2 weeks ago, i was driving when i heard the whine noise. i got home and saw fluid dripping down from the t-case. i thought it was the drive shaft seal at the time but i don't think it's the case now. there were plenty of fluid coming out off the t-case when i drained it (about 1.5 qt.) and it was pretty thin (there were also some metallic in the oil). i checked the tranny fluid and it was low, i had to add a whole quart (used 3 quarts when i changed it). my conclusion was that some how tranny fluid got into the t-case and made it overflow and causing the ring and pinion in the t-case to go bad.

i'm not familiar with evo tranny but i would guess that the oil would have to go pass the tranny seal and then the t-case seal. it's odd that two seal would go bad at the same time, unless there's only one seal that separates the tranny fluid from the t-case fluid. i'll be pulling the t-case and sending it to TRE or Shepherd soon. i just don't know if there's anything wrong with the tranny and should i send it off also. i would rather have a local shop do the tranny though. does anyone know if TurboTrix do tranny service?

thanks in advance.

 

there's gotta be someone here who knows what i'm talking about.

 

There's only one seal.

 

Was that your Blue evo I seen at 2 oclock on a flatbed on rt30 heading towards york mitsu???

 

so if that one seal go bad, it's possible for tranny fluid to leak into the t-case. thanks,

 

no, my car is still at my house. i'm going to do all the work myself, except for the t-case rebuild.

 

Oh, I just found it ironic to have seen a blue evo on a flatbed on the way home from class and then to see your post. hehehe.

 

anymore opions?

 

interesting, never heard of this before. changed your clutch recently?

 

the tranny has never been off the car. i do plan on changing the clutch if i need to pull the tranny.

 

i have a tre transfer case i like it but i think its leking and i just got my car back for the shop like 2000 miles ago

 

i need to know why my transfer case would be leking email at wackevo8@yahoo.com on msg me on myspace at http://www.myspace.com/gt35rturbolagis4play plz if anyone can help me oh its has 8700 miles on it

 

A common reason for the leak that started this thread is when people try to reuse the old O-ring that fits between the transmission and the transfer case.

 

Yes that is correct. if it is pinched (like during a install) or goes bad for some reason your tranny/tcase fluids can mix. The tcase won't like that much.

 

That’s the answer I was looking for. I think that’s what happened in my case. I initially thought that the rear drive shaft seal was bad and that’s where the leak came from, but when I drained the t-case, I was surprise to see how much fluid came out. And the tranny fluid was about a quart low. That’s why I think the tranny fluid leaked into the t-case and caused it to overflow and ruin the ring and pinion (maybe even the front diff).
