Any suggestions or advice would be greatly appreciated..
87 GT 5.0 automatic. A few bolt-ons to the motor/exhaust, otherwise all stock from block to rear wheels. Fellow slowly pulled out in front of me on the highway, so I jumped on it to pass him...felt a sotp clunk, and began losing power..
I've changed the tranny filter / fluid, no change. Fluid had no metal shavings, and wasn't burnt, though it was fairly dark with sediment.. I'll try to describe what's going on: First seems to slip a bit, but it'll still move. The shift to second is so mushy I can't really feel it, and second feels like it's slipping even more than first. Not sure if I'm using the right word - by slipping, I mean that the acceleration doesn't seem to line up with what the motor is giving.. It'll hold around 38 mph, at about 2000 rpm, without downshifting. At roughly 45mph/2600rpm it loses all power completely, almost as if it's in neutral with zero resistance against the motor...I =think= it's shifting to third there, because it stays powerless until I bring it back down to about 15mph or so..
Plan for the weekend is to drop the tranny out and dig into it, with a couple friends who are much more familiar with transmission concerns than me. I'm pretty damn ignorant on them. Any ideas about what we might look for? Also, any links that might help me get a crash course in how the AOD + torque converter actually work? I've got roughly zero idea what's going on inside there, and Chilton isn't terribly helpful in that regard..
