Get these sensors check the CTS/TPS/VSS these guys tells the TCM/PCM the throttle and governor pressures which provides the shifting/lock-up of the tranny-computer don't get the right signal it will not shift/lock properly.

Way back during the plastic bag we use intake vacuum to provide shifting-now its all electronically controlled.
