Quick Learn Procedure

The Quick Learn function customizes adaptive parameters of the TCM to the transaxle characteristics of a vehicle. This gives the customer improved "as received" shift quality compared to the initial parameters stored in the TCM.

The Quick Learn function should be performed:
- Upon installation of a new service TOM
- After replacement or rebuild of internal transmission components or the torque converter
- After moving a TCM from one vehicle to another. NOTE: This is not a recommended procedure.
- If one or more of the Clutch Volumes Indexes (CVI's) contain skewed readings because of abnormal conditions.

To perform the Quick Learn procedure, the following conditions must be met:
- It is imperative that the vehicle be shifted into OD with the engine running and the oil level set to the correct level. This step will purge the air in the clutch circuits to prevent erroneous clutch volume values, which could cause poor initial shift quality.
- The brakes must be applied.
- The engine must be idling.
- The throttle angle (TP sensor) must be less than 3 degrees.
- The shift lever position must stay in neutral until prompted to shift into OD.
- The shift lever must stay in OD after the "Shift to Overdrive" prompt until the DRB indicates the procedure is complete.
- The oil temperature must be between 60-200°F.

NOTE: The above conditions must be maintained during the procedure to keep the procedure from being aborted.

The Quick Learn procedure is performed with the DRBIII by selecting "Transmission" system then "Miscellaneous" functions, then "Quick Learn". Follow the procedure instructions displayed on the DRBIII.

The nature of the Quick Learn function requires that certain features must be taken into consideration.

- Before performing Quick Learn, it is imperative that the vehicle be shifted into OD with the engine running and the oil level set to the correct level. This step will purge air from the clutch circuits to prevent erroneous clutch volume values which could cause poor initial shift quality.

- DO NOT take a TCM that has been "Quick Learned" on one vehicle and install it on another vehicle without performing Quick Learn after installation, Quick Learn adapts the TCM to the particular characteristics of a vehicle's transaxle. Placing a "learned" TOM on another vehicle without doing Quick Learn after installation may result in poor shift quality.

NOTE: Swapping of production TCM's is not a recommended procedure.

- If an unused TOM is installed on a vehicle with a HOT engine, Quick Learn will cause the TOM to report a cold calculated oil temperature (non TRS) This requires monitoring the calculated oil temperature using the DRB. If the temperature is below 60° F, the transaxle must be run at idle or driven in gear until it goes above 60° F. If the temperature is above 200° F, the transaxle must cool to below 200° F.

- First gear is engaged in overdrive after Quick Learn is completed. Place the vehicle in park after performing Quick Learn.
