Hello all, I am new to this Forum and hoping for some good advice. I have a 1998 Grand Prix GTP Daytona 500 pace car. It will hold back on a hill for a short distance , then kick out as if to nuetral or shifting to a higher gear. I can engage the throttle slightly and the transmission holds back again for a while. I changed the fluid and filter, and also installed a transgo shift kit while I was in there but it did not seem to help much. I suspect some electrical problem. The trans does not slip in any gear under hard throttle, but I did notice the performance shift light will no longer come on. Any Ideas?
