i would definitely try to figure out if the motors running well first. in a perfect world that motor should go and the trans should try to keep up behind it. their are some trans things like shift points and kick-down that are controlled by the engine sensors. but by no means will the motor quit or run funny if the trans is toast unless something goes horribly wrong with the torque convertor and it locks up solid instead of spinning freely. then again, on the old solid aluminum intake, they tend to be laggy all the time, running well or not. definitely MAF cleaning, plugs and wires, vacuum leaks, etc.
cars that hop out of gear, or slam in hard are usually a trans problem, but cars stumbling or falling flat on their face is a sign of something motor related to me. and a lot of those slips are fluid level related, be it low, or even overfull. and everyone hers right, driving a trans while slipping or low on fluid will destroy it, especially driving hard. you'll tear up your clutch-packs and contaminate the fluid with excess clutch material. you' also burn the fluid, which you can smell. its awful smelling, especially if its mercV which smells terrible fresh...
that being said, those 95 and down 4R70W's are horrible, and if your having issues with it sliding into gear or slipping out, its most likely toast. check the fluid... perhaps change it for some mercV and hope for the best is all you can really do. otherwise a 98+ trans with a harness repin will treat you so much better.
of course if your turning while accelerating and it slips out it could very well be your trans pan and filter. the 96+ pan has a deep sump tube and dimple that pickup fluid at a lower level in the pan eliminating the dry sump issues when taking hard turns on the 95 and older setups.
RUST!! eating away at me more than the rear fender wells
