What would you do? auto trans question

Thanks, that helps a lot. I guess I can go ahead, and install the transmission. I think I would like to have a stock valve body, and get it working properly, then worry about modifying it later. Your answers tell me a lot, but would the pressure adjustment being off keep me from adjusting the shift points?
Yes. The normal shift kit instructions usually say to adjust the regulator spring (the allen wrench one) where you can fit a 5/16 bolt between the plate and cage. Depending on which spring is under the cage this can be too much and be over riding any signal from the kick down. Like the beast said I would back off the regulator a bit and see what happens. This can be done in car.... Needle nose vice grips may be required though....
