WARNING: This page is about a different variant/trim than selected.
CAUTION:
- As the TCM consists of precision parts, the TCM will be damaged if it is exposed to an excessively large impact. Handle the TCM carefully so as not to impact it.
- When the TCM is replaced with a TCM from another vehicle, failure to initialize the learned values in the replacement TCM can result in excessive shift shocks. Always initialize the learned values when using a TCM from another vehicle. TCM Learning Control Initialization
