part number request

[dhen]

OK, so I have a very large leak at the back of my transmission. It's a JDM 5-speed. What kind of car should I say I have to get the seal? Is it the same as a 1990 240SX?

BTW, is there any unwritten trick to replacing this seal? I have the manual, but I've never done it before.

Thanks,

Darian

At the back of the transmission? Are you referring to the output shaft seal? Post up a picture of what you're looking at to help us figure out how best to help.

Yes, you are correct. Where the driveshaft goes into the transmission. I think I damaged it when I put the driveshaft in because it's leaking like a sieve...

should be the same as the 240SX ones
I know the dust sleeve is different but it's not something to worry about

[dhen]

The dust sleeve just pops out, correct?

It's the same as the 240sx.

Dust sleeve is just pressed in there lightly, so tap it out with a flatblade and a hammer.

I have never seen one leak though, are you sure you don't have too much fluid in there?

[dhen]

I'm not sure because it's impossible for me to check with my setup. It leaks as fast as I fill it, though.

I'm not sure if my rear transmission seal is leaking, but I always do see a drop of gear oil waiting to fall off that little rectangular part that's sticking out of the bottom of the rear of the transmission.

I haven't really investigated it much because my transmission started feeling like it was hard to shift, so I went ahead and changed the gear oil, expecting it to be low since I saw the leak. however, it had a lot of oil still in it, and didnt seem to feel a whole lot better when I put fresh 75w90 in it (maybe a little better).

I don't think I put any kind of RTV or gasket under my B&M shifter. Dunno if that would cause much of a leak.

let me know how it goes if/when you change out your rear trans seal. good luck!

A drop or two I can live with, but this isn't holding oil at all. Like I said, I think I damaged it when I installed the driveshaft.
