lets say I am an idiot when it comes to automatic transmissions. I am drag racing an early eighties malibu that I bought turnkey. big block with a powerglide. last week when I pulled high gear the trans case cracked along side the cooling line bosses which I know is a common problem. I took a stock power glide and pulled it apart for the case. the broken case has a sticker on it that says RW peformance transmission on it. just by looking at it I didn't see any modifications to the case. I took every thing out and installed it in the stock case. didnt see much of a difference except the pump by the tailshaft and no govenor. I have a revers manual valve body. when I installed the trans in the car and started it (on jack stands of course), put it in reverse and the wheels started to turn in reverse but as soon as I touched the throttle they go forward. any idea where I went wrong?
are you saying the busted trans didnt have a rear pump, but the one you have now do? i would think there would be a dif. in the valve body.
