	If impossible, the transmission compensation code cannot be read from the previous ECM Set transmission compensation code (step 1)*2 Perform road test to allow ECM to learn	Large shift shock Engine overruns

*: When performing learning using the Techstream.

NOTE:

After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.
