Nope.. the only thing that can cause the trans to shift hard is when the computer commands it to. And coincidentally... the computer will command a hike in line pressure in the trans(which produces hard and late shifts) when it loses contact with one of the major powertrain sensors(speed, TPS, MLPS) or there is a problem inside the trans that it has detected. So... what codes are present?

Thanks fro reply. I think the code read 624, have to find paper wrote it on to be sure. Anyway it said it was the ' EPC, electronic pressure control solenoid failure'.
