1997 Chevrolet 3500 pickup: Most of the time the transmission shift very had between the gear, most noticeable when shifting into 3rd and 4th and when under a lot of power. I have changed the fluid twice and the transmission filter once which seem to help a little. If you let up on the throttle to force a shift it is a little less pronounced.

Have these sensors check-throttle position, vehicle speed, coolant temperature. The computer needs the input signals from these sensors in order to command the transmission to upshift/down/lock-up by activating a given shifting solenoids.
