replaced speedometer driven gear with recommended 40 tooth and still not accurate...

I'm going to double check that. I think so but I'm not sure... I've asked that question to Mancini, my transmission builder and another trans shop and they said it shouldn't make a difference. I've also read online that if clocked incorrectly it would put more pressure on the driven gear if that was the case. The gear numbers of the driven gear should be located at 6 0'clock - is that correct?


Look in the service manual and it will explain how to clock the housing for the number of teeth on your gear....
