- Before replacing an automatic transmission: Input the data into the TCU using the GDS.
- Before replacing an ECU/TCU: Back up the oil pressure data from the old TCU into the GDS and then transfer the data to the new TCU.
NOTICE
Before installing the transmission, the technician should use GDS to transfer the pressure characteristics to the TCU. If not, take a photo or record all digits on the tag.
