thanks for all the input. I removed the tranny today it is a cast iron power glide put it one the bench and ripped it apart, found the hi clutch pack had been slipping, also found rear pump housing cracked. so far haven't found source for pump but I do have in my get to some day line of cars a 62 impala which has a 235 and an alumin case power glide so I think I will just pull that one and put in pontiac. when I get to impala I would like to put in sbc and turbo 350 anyway. this will give me a good reasin to do so.
