Soooo, I dont think my kick down is working. 89, V2500 Burb with TBI 350.I metered the connector at the trans with the key on and held the pedal at WOT and found no voltage. I DO NOT have a switch at the top of the gas pedal, OR the throttle body. So, im assuming it computer controlled through the ECM(which is less than a year old) using the TPS to tell the trans when WOT is achieved. Can anybody confirm how the kickdown works on TBI models?
