I need more ideas about auto trans. replacement. John at Z1 has a rebuilt for $1200, that is one of the best prices I have seen. Lets hear cheaper ideas. For example: tranny-be-new additive from the folks who brought us Blinker fluid, and muffler bearings. What has everyone done that had their auto's take a poop? Does everyone just replace it, is there an inexpensive high-performance tranny that could be swapped? Lets hear the ideas.
