Leak at tail shaft

That totally sucks. I can only think of two good permanent solutions. The first is a new tailshaft housing. The second is to weld the void closed and then remachine the seal seat on a lathe. Liquid steel or the like dressed very carefully with fine emery cloth might work, but then again it might not work long.

Good luck,

The car has had a slow tranny leak since I've owned it till one day parked on an incline it all started to flood out. I replaced the real tail shaft seal which has brought the leak back to mere drops a day. While doing the replacement I noticed the remains of some RTV around the inside where the seal goes. Then I found out why. There is a small crevice in the metal, not a crack just a strange cleft where the inside ring of the shaft isn't completely smooth. Apparently this imperfection is the cause of the leak. I don't know how the cleft could have occurred as the spline never touches the area and there are no other pits of scars around it. Factory defect perhaps. In any case I would like to be able to shore up this leak permanently. I need to do something to allow the seal to seat perfectly so rotary tools are out of the question and I already know RTV will not do the trick for long. Any suggestions would be greatly appreciated.

If im thinking of the same part as you, it is actaully a press in bush. It would most likely have been damaged during fitting. You can simply remove the extension, and have a trans shop replace the bush andseal and you should be fine.

What about some JB Weld? If it works on engine blocks it would probably be a good fix for that problem. Like Jahardy said it does totally suck, but you can end the nice pools of red liquid in the driveway
