87 Toyota PU trans leak
Got a guy at work he has an 87 Toyota PU 2.4ltr 2wd auto and we replaced to output shaft deal but fluid is still leakin past the seal after about 2 minutes of the truck running we replaced the seal 3 times since Saturday and still leaking anyone have any idea what would cause this? Tried looking for TSB's but found nothing.

Re: 87 Toyota PU trans leak
It's probably a bearing problem. If the bearing has too much play, the shaft can move around too much and deflect the seal enough that it won't seal properly when the shaft is rotating. It's also possible that damage or corrosion on the shaft is destroying the seal surface. There may be another seal inside the tailhousing also, instead of just the outer seal. I can't remember if that's common or not; I know about sealing but nothing about 1987 Toyota automatic transmissions.

Re: 87 Toyota PU trans leak
seal is not damaged and i talked to a friend and he said something about an extension housing bushing i guess inside the extension housing that if that goes bad it can cause fluid to leak so far 3 people have said the same thing about that bushing so i think im gonna try to replace that bushing then go from there. thanks for the info guys.
