My little drag car is now a dud off the line. I had the transmission built last week and it shifts fine but the shop replaced the torque convertor that was in the car with one they selected that had a high stall speed. I went back to the shop this morning and they are going to try to locate my old convertor and have it rebuilt. I never got to drive the car with the transmission working correctly and with the old torque convertor but the couple of times I did launch it, even with a slipping transmission, I got a pretty good hole shot. Now the buzzing half dozen/leaning tower of power Dodge Dart is a real dud. I checked on a built racing torque convertor and it will cost me $600.00. I can not put that much money into the car. Do any of you know of a factory alternative for the 904 transmission that will help get a higher stall speed?
