Mechatronic assembly

NOTE: The only solenoid that is serviceable in the mechatronic assembly is Shift Solenoid E (SSE). If the mechatronic assembly is being removed due to a faulty SSE , follow the specific steps in this procedure to install a new SSE . If the mechatronic assembly is being removed due to a faulty solenoid other than SSE , a new mechatronic assembly must be installed.

NOTE: If a new or existing mechatronic assembly is installed, the Transmission Control Module (TCM) will need to be programed with the latest calibration.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .

NOTE: Do not pull on the wire harness to disconnect the connector or damage to the connector will occur.

Disconnect the transmission vehicle harness connector by twisting the outer shell and pulling back on the connector.
Remove the transmission fluid fill plug transmission fluid level indicator assembly located on the passenger side front portion of the transmission case. Removal of the transmission fluid fill plug will relieve any vacuum that might have built up in the transmission. This will aid in allowing the transmission fluid pan to be easily removed when the bolts are removed.
