Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Transmission Identification
PCM controlled transmissions have a solenoid strategy identification tag located on the left side of the transmission case with a 13-digit solenoid strategy number. The solenoid strategy is correct if the 13-digit number displayed on the scan tool matches the number listed on the tag. If the numbers do not match, then the solenoid strategy identification etched on the main control will need to be compared to the identification displayed on the scan tool. The solenoid body strategy must be downloaded to the PCM if the identification on the main control does not match the identification displayed on the scan tool, or transmission damage may result. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 6R80 .
