Several months ago, I posted about a leak on my truck. I have a 1985 GMC Suburban 1/2 ton 4x4. It has the 700r4 trans. I rebuilt the trans about 2 years ago because I burnt it up with a TV cable problem. Not real bad, but it was slipping some under load. Anyway, the rebuild went fine. No problems at all. Then about 6 or 9 months ago he front seal started leaking. I posted here about that and the conclusion was that the pump bushing could be worn out (as I neglected to change it) and the front sealand bushing should be relplaced. Also someone stated that the forward clutches could be burnt causing a leak.
I did not have the time to fix it, so I parked it for a while. I finally got a chance to work on it his weekend. I replaced the pump bushing and front seal. The seal didn't look too good, and the bushing was bad. The converter showed only minor wear, nothing bad. I used a new gasket and seal for the pump, of course. Now I still have a leak. At first, I though it was a cooler line, but that was not it. I cleaned the area with brake cleaner and let the truck sit and idle. The fluid is dripping off the starter and running down the flywheel cover and onto the right front corner of the trans pan. It is not dripping forn the drain hole on the flywheel cover anymore, so I don't think it is the front seal. The trans was only slighly warm and I never put it in gear, just watched as it stated to drip, so I can't imagine that the forward clutches would have anything to do with this. It is not coming from the TV cable, servo cover, or dipstick tube. I guess I will have to pull the flywheel coer off later tonight or tomorrow, but I cant think of where it could possibly leak. Any ideas?
Oh, by the way, when I took the pan off there was only minimal reside in the pan. No clutch reside.
