Rear - Transmission seal question

1500 engine and transmission - remember I have an access hole cut with the later engine.

Was under the car tonight working on the oil pump and noticed a circle of oil directly under where the rear of the transmission meets drive-shaft - with a comparable drip of oil at that joint and a "swirl" of oil markings around the inside of the driveshaft tunnel.

So, is it possible to do it in situ? or do I have to pull the engine? (which I really don't want to do)

thanks all!
 
JP,

I don't have that much experience with 1500's but from what I see in the parts book and the shop manual, the rear seal replacement is much more straight forward the the A-series gearbox. Unlike the smooth/rib case, the 1500 gearbox uses a conventional style lip seal. Provided you have a large enough access hole to get your hand it, you should be able to do it. You'll need to be able to pry out the old one, and squarely tap or push in the new one. You'll have to evaluate how much access you have for the tools you have.
 
I can't remember but I believe thinking it must be a pain trying to do it in the car when I looked at it. IIRC you have a nut you'll have to break loose first. I'd leave it be and just keep an eye on level. FWIW, my top cover leaks and it looks far worse (the leak) then it actually is. Granted, I have a lift and checking it is easy for me. Most quick lube joints will check it for you for free. Well, at least they used to.
 
I forecast weeping and gnashing of teeth if you try to do it in place. It took me a long time with an even longer breaker bar just to get that rear nut off the tail of the tranny. I don't see how on earth it can be done through the access hole, either from the top or the bottom; and then prying off and tapping the seal on squarely will be another tight-quarters challenge. (This is just working off the memory of disassembling my tranny from a couple of years ago.)

I'm guessing it'll be loads easier with the engine pulled. 'Twere me, I'd think of two or three other things you can do for Miss Triss while her engine is out to make it worthwhile, and get it all done at once.
 
Aha... I didn't realize it didn't have the slip yoke arrangement like the A-series. That was shown on a different page of the parts book. Yep, that changes the whole scenario.
 
JP, it just means your seal is well lubricated to prevent future wear. :highly_amused:
