This is how I know what air shocks will do to sheet metal. Also, my Dad and brother Bill are into 50's shoe-box Fords, so they take up a bunch of time too. Problem is my Dad's '66 T-bird keeps sidetracking me with electrical and vacuum issues. I'm almost done with a '79 Trans Am and then I plan on doing a resto mod to a '72 Firebird.
I was thinking about getting another LSC project car but I'm swamped with other projects. I don't know myself, trannys are like voo doo to me.
My buddy said that it burns up the servos because it will shift too hard. Apparently on the AOD they would rust up and freeze but this issue was probably in addition to the bushing or that was just how he explained it. My friend said that it was a bad kickdown cable, it had a different name that I can't remember. The second time I burnt up the trans I got rid of my transmission guy and then sold the car to a friend that was into Fords more than me, I'm more of a non-Chevy GM guy.
