Additional Service When Replacing TCM And Transaxle Assembly: Description

WARNING: This page is about a different car, the 2020 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.

When replacing TCM and transaxle assembly simultaneously, perform the following work. For work procedure, refer to Work Procedure .

NOTE: The CD provided with the new transaxle assembly contains important calibration data that must be installed with CONSULT after installation of the new transaxle assembly. Do not discard the CD.

TCM PROGRAMMING

Since vehicle specifications are not yet written in a new TCM, it is necessary to write them with CONSULT.
CAUTION: When replacing TCM, save TCM data on CONSULT before removing TCM.

WRITING TCM DATA

TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. For this reason, after replacing TCM and transaxle assembly, it is necessary to write new data in TCM.
