Ok so I'm going to start working on the fox again. It needs a new rear main so when I change it I'm going to put a new tc in that I've had awhile. The trans doesn't slip but I wonder if I should save for a "new" rebuilt like a monster or just get a new vb or shift kit. What kind of life expectancy do aod's have? Motor is stock w boltons but maybe heads one day. If I go just vb what do u guys like for a middle of the road besides the $400 lentech?
