Trans leak

[project 92z]

Today I was working on the "money pit". The vacuum module (black plastic module that holds the map sensor) is broken at the line that rings along the fuel rail so I'm trying to repair it with more vacuum tube, vacuum hose and jb weld. While all that was setting up, I decided to look for the trans leak.turns out it's the dipstick seal. Anyone ever tackled that job? I had to head out to work and didn't really look at it closely. I wonder if it's the norm cheap part = huge job.

I can't picture an o-ring or anything on there. How much fluid is in this transmission? That seems awfully high up.

I had to remove the dipstick tube for some reason before..... LOT of fluid came out with it, along with the seal. I want to say it was only one or two bolts, but they're a pain to get to.

Sounds about right.  I'd expect the new-style "top-hat" seal rather than the old "o-ring"; although I've not had mine apart.

 

The old O-rings would flatten (compress) with age and seep, but the real problem seemed to be that when the tube was rolled to form the O-ring groove, the tube would work-harden and crack.  If the tube has an O-ring seal, inspect the tube itself carefully.

 

The "top-hat" seals are a pain in the ass, but seal very well once installed.  I always had to lube the inside and the outside of the seal, start the seal into the case, start the tube into the seal, and THEN cram it all into position.  If the seal was all the way in the case, I couldn't get the tube started.  If the tube was all the way in the seal, I couldn't get the seal into the case.

I once used the wife's chest freezer for one of those...put the dipstick tube in a garbage bag, and let it freeze for a while, then put on the still warm top hat, and put it back into the freezer.  After both are cold, install it in the trans.  Either I got lucky, or this method worked--since I only did it once, it could possibly be either.

I'd imagine its a part a transmission shop or dealer would have for very cheap

 

usually a single bolt that holds the tube to the transmission case then it pulls straight out, you'll loose fluid. Might be a good idea to do a pan drop and do the filter and put fresh fluid in it at that time too.

 

Cant imagine the seal it self will be hard to change.

This probably won’t help.

 

Rockauto under Transmission / Seal / Oil filler tube seal.

 

 

Probably Pioneer 7600145.

This is probably rubber, since it's a seal. But my heart skipped a beat when I saw the picture! It looks just like the convertible top lock pin guide!

Same thing I thought /\
