AA80E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: REGISTRATION

NOTICE:
* When the automatic transmission is replaced, the transmission compensation code must be input into the TCM (proceed to step 1).
After the automatic transmission is reinstalled, the Quick Response (QR) code label will be positioned where the code cannot be read. Therefore, before reinstalling the automatic transmission, record the transmission compensation codes or input them using the Techstream.
* When the TCM is replaced, the existing transmission compensation codes must be input into the new TCM (proceed to step 2).

1. SET TRANSMISSION COMPENSATION CODE INTO TCM (step 1)

NOTICE:
Transmission compensation codes are unique, 60-digit alphanumeric values printed on a QR label on the transmission. If an incorrect transmission compensation code is input into the TCM, shift shock may occur.

(a) Record the transmission compensation code specified on the QR label.





HINT
The transmission compensation code is a 60-digit alphanumeric value imprinted on the QR label.

(b) Move the shift lever to N or P.

(c) Connect the Techstream to the DLC3.

(d) Turn the engine switch on (IG).

NOTICE:
Do not start the engine.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / ECT / Utility / A/T Code Registration.

(g) Select "Set Compensation Code".

(h) Register the compensation code.

(i) Manually input the transmission compensation code.

(j) Check that the compensation code displayed on the screen is correct by comparing it with the 60-digit alphanumeric value on the QR label.

NOTICE:
If an incorrect transmission compensation code is input into the TCM, shift shock will occur.

HINT
Input letters and numbers using the Techstream.

(k) Set the compensation code into the TCM.

2. TRANSFER TRANSMISSION COMPENSATION CODE (step 2)

NOTICE:
Transmission compensation codes are unique, 60-digit alphanumeric values printed on a QR label on the transmission. If an incorrect transmission compensation code is input into the TCM, shift shock may occur.

HINT
The following operation is available for use when a TCM that is being replaced can still transmit its registered transmission compensation code to the Techstream.

(a) Read the transmission compensation code.

(1) Move the shift lever to N or P.

(2) Connect the Techstream to the DLC3.

(3) Turn the engine switch on (IG).

NOTICE:

Do not use the code specified on the transmission QR label even if the transmission compensation code cannot be read using the Techstream. The code printed on an in-service transmission may not match its current characteristics. Replace the TCM with a new one and perform a road test to allow the TCM to learn the transmission characteristics.

(7) Turn the engine switch off.

(8) Replace the TCM.

(b) Set the transmission compensation code.

(1) Turn the engine switch on (IG).

NOTICE:
Do not start the engine.

(2) Turn the Techstream on.
