I see your point with the power problem, I'm not driving my 89 because it suddenly cuts out and and goes randomly. The electric is just beat, it's bad. Going to change everything. I just blew the tranny in my jalopy and stole a 700r4 from the brown van. It gave me problems, slipped and shifted bad. I took a chance and got a kit from trans go. Works perfect. I don't know what you want to spend but your in the 200 $ range in parts. If you have good power and the drive train module is good, this may be the way to go. Ohh what I ment about the gasket is if it was installed upside down it covers a hole in the pan rail and you get no 4TH, very easy to screw up, there's a notch in the gasket to clear the hole.
