I ran my 1986 700r4 tranny behind a 1994 5.7l for 6 months before i got an electronic 4l60e to replace it and make the computer happy. The value of the TV cable though, cannot be overstated. The cable for the 700, will fit directly into where your cruise control cable is plugged into now. Just make sure you adjust it correctly!
As for your 4l60e, mine went out the same way. The 3/4 clutch pack is slipping. Either a lack of internal fluid pressure is not holding the pack tight when the fluid gets warm, or the pack is just very worn and the reduction of pressure by warm fluid is causing it to slip. Same difference. It will do this till it wont drive in 3rd or 4th at all. I would know. The parts arent that expensive if you are inclined to do it yourself. You can have it rebuilt by a shop for around $750 give or take, if you take the tranny out yourself. Good luck

Oops, forgot to say. The clutch packs on the v8 tranny are different than the v6's. So if you have it rebuilt, make sure you tell them its for a v8, otherwise the extra power of the v8 will burn out the new one too in short time.
