Shift the Transaxle

SHIFT THE TRANSAXLE

Before diagnosing the control system, you should perform one more check on the transaxle itself. You are going to shift the transaxle by providing the electrical signals that should have come from the control system. To do this, run two 12 volts leads from the battery to the transaxle. Disconnect the solenoid wires from the transaxle and connect your 12 volt leads in their place. Originally the transaxle had 1 red wire for the direct clutch solenoid and 1 yellow wire for the 2nd gear solenoid. With both 12 volt leads attached you should be in first gear. Accelerate on the lift and remove the wire to the 2nd gear solenoid. The transaxle should upshift to 2nd. Now remove the wire to the direct clutch solenoid and you should shift to 3rd. If this checks good, then your problem is probably external to the transmission. You now need to check the electronic control system.
