I just bought a '92 Transport SE with a 4T60-E in it 3 days ago. I THINK I have a leak in the transmission's lower pan...tell me what you think - I'm about this close to throwing my hands up on this one:
When I bought the van, the fluid was really low - barely on the end of the dipstick, and it was losing overdrive. So I filled it up - tranny worked fine. However, within less than 100 miles, I had to put over 1/2 gallon into it! I finally discovered that it seemed to be leaking at the rear driver side corner of the pan.
I grabbed a filter/gasket kit and swapped it earlier today. I used a 1/2" ratchet to tighten down the bolts, working from the center of the front and rear rails out towards the sides. I snugged the bolts down just until I could see the gasket (a rubber gasket, not cork) barely starting to compress out the sides. Barely. I didn't notice anything wrong with the pan at the time, but I didn't check it with a straightedge or anything while it was out - that would have made too much sense.
So I drive the van today, probably less than 15 miles, and it's leaving fluid ever place I stop, but now it's only on the back edge of the pan that drops are forming (and on the rear mount bracket to a degree) but it's still towards the driver side. I'm assuming it's leaking while I'm driving too, but I've never climbed under the van while doing so to check.
Tonight I decided I was going to find out, once and for all, what the heck is going on under there. So when I got home, I left the van running, jacked up the front and put it on stands, climbed underneath, and could not see any source above the rear pan rail that could be putting the fluid there. I then decide to check the bolts again, and they seemed to be somewhat lose. They weren't less than finger tight, but it was REAL easy to turn 'em with the 1/2" ratchet again. So I figured that I would need to resnug them and that'd be that. I do so, take the van out for a spin, and when I come back into the drive and crawl underneath, I'm watching the fluid drip more than 1 drop a second off the back edge of the pan. I had a good sized puddle within less than a half minute. After a minute or two, it tapered off and you'd only get the occasional drop.
At this point, I packed up my tools, parked the van, and here I am.
Any help would be appreciated.
