Hi folks, due to a minor differential leak where it butts up to the transmission, I have just spent about 12 hours replacing the 6" O-Ring and the seal in the plate that sits between tranny and the differential only to still have a minor leak. Besides my frustration I'm starting to wonder if I might have an transmission output shaft wobble causing seal failure. I replaced the transmission output shaft seal 2 years ago when I got the car.

Not sure where to go with this. A tranny shop, a dealer or such up another few evening to pull it all apart again.

Any thoughts or advice is much appreciated.
 
So the local transmission shop here in Ottawa says 1/16" movement (MAX) (top to bottom or side to side)....I'll check mine tonight but think I may be facing a new or rebuilt transmission....Arrrrhhhh.....the excess movement is testing the output shaft seal causing the minor leak :-(

So I thought I would report my findings.......my output shaft has just one .125 or 1/8th play top to bottom. I've put all new seals in and have my fingers crossed that it hold out if not it will be time to spend some dollars. I will admit that I am getting pretty damn good at taking the whole rear sub-frame down.....between 7 and 8 hours this time. I must be honest and admit that I have a four post life in the garage and that makes a major difference...not sure I would do it on the floor at 50 but that it what we had to do back in the day.

To no great surprise, she continue to leaks :-( Oh well what can you do other than call the specialists.....I'll jump on that when I have a few minutes at work tomorrow so stay tuned to see what a transmission rebuilt is going to set me back.
 
Awwww..... that's a shame Racer. 1/8 doesn't sound like much but it is what it is. I hope you are surprised with the rebuild and it turns out as good as it can be.... All I can offer is advice to pick a good shop.... :)
 
So a brand new transmission is on order. Besides the run out of the output shaft the transmission hosing has a crack in it also, both leading to the leak. Hope to be back up and running by next weekend when I start vacation. Let's hope there is some cash left for gas!!!!
 
I'm back on the road again! With a 3 year 160,000km warranty to boot! Just need a good 4 wheel alignment that my brother will do for me after work tomorrow. Savings are over rated anyway!!! LOL! 5 Grand all said and done! As my mum used to say "you cant take it with you"!!!
