Transmission Control Module Adaption

WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: The Transmission Control Module Adaption routine requires one person to drive the vehicle and another person to monitor the progress of the routine. Failure to follow this instruction may result in personal injury.
NOTE: The Transmission Control Module Adaption routine is also known as the Gearshift Quality Adaption routine.
Before performing the Transmission Control Module Adaption routine, ensure that any engine system faults have been rectified.
Before performing the Transmission Control Module Adaption routine, ensure that the powertrain control module has been configured with the latest level software.

The Transmission Control Module Adaption routine is used to teach the transmission control module the characteristics of the automatic transmission components. The quality of the gearshifts will improve as each adaption is completed. Adaptions will occur automatically during normal driving without the use of the Jaguar Land Rover approved diagnostic equipment, but the process will take longer.

The Transmission Control Module Adaption routine should be performed:

After installing a new transmission control module.

After installing a new automatic transmission.

After installing a new valve block.

If one or more of the adaption values for each gear is equal to or less than 3.

When performing the Transmission Control Module Adaption routine, it will be necessary to drive the vehicle at speeds between 20 and 60 mph (32 and 96 km/h). A suitable road test area should be identified where the vehicle can be driven, ideally without stopping, for up to 5 miles (8 km). If a dynamic adaption cycle is interrupted (for example, by slowing down or stopping), re-select the relevant gear and continue driving. It is not necessary to restart the routine. Before performing the Transmission Control Module Adaption routine, drive the vehicle normally to raise the automatic transmission fluid temperature to at least 50°C.

After driving to the road test area, perform the following steps:

  1. Using the Jaguar Land Rover approved diagnostic equipment, perform routine - Transmission Control Module Adaption.
  2. Dynamic adaption - Clutch E (3rd gear):
    1. Drive the vehicle at a speed of between 20 and 30 mph (32 and 48 km/h).
    2. Using command shift, select 3rd gear and drive with light throttle inputs and a steady engine speed between 1150 and 2300 RPM.
    3. Using the Jaguar Land Rover approved diagnostic equipment, monitor the 'Engine Torque' and 'Engine Speed' displays - Increase or decrease the throttle input as necessary to keep the values within range.
    4. Monitor the 'Adaptions 1', 'Adaptions 2' and 'Adaptions 3' columns for clutch E.
    5. Continue driving until a green tick is displayed in each of the three columns for clutch E.
  3. Dynamic adaption - Clutch D (6th gear):
    1. Drive the vehicle at a speed of between 40 and 50 mph (65 and 80 km/h).
    2. Using command shift, select 6th gear and drive with light throttle inputs and a steady engine speed between 1150 and 2500 RPM.
    3. Using the Jaguar Land Rover approved diagnostic equipment, monitor the 'Engine Torque' and 'Engine Speed' displays - Increase or decrease the throttle input as necessary to keep the values within range.
    4. Monitor the 'Adaptions 1', 'Adaptions 2' and 'Adaptions 3' columns for clutch D.
    5. Continue driving until a green tick is displayed in each of the three columns for clutch D.
  4. Dynamic adaption - Clutches C and B (7th gear):
    1. Drive the vehicle at a speed of between 55 and 60 mph (88 and 96 km/h).
    2. Using command shift, select 7th gear and drive with light throttle inputs and a steady engine speed between 1150 and 2500 RPM.
    3. Using the Jaguar Land Rover approved diagnostic equipment, monitor the 'Engine Torque' and 'Engine Speed' displays - Increase or decrease the throttle input as necessary to keep the values within range.
    4. Monitor the 'Adaptions 1', 'Adaptions 2' and 'Adaptions 3' columns for clutches C and B.
    5. Continue driving until a green tick is displayed in each of the three columns for clutch C.
    6. Continue driving until a green tick is displayed in each of the three columns for clutch B.
  5. Static adaptions:
  1. Stop the vehicle.
  2. Apply the brakes. Keep the brake pedal depressed until the static adaptions are complete.
  3. Set the transmission control switch to 'Drive' and wait for 5 seconds.
  4. Set the transmission control switch to 'Neutral' and wait for 5 seconds.
  5. Perform sub-steps  3 and  4 a total of five times.
  6. Set the transmission control switch to 'Reverse' and wait for 5 seconds.
  7. Set the transmission control switch to 'Neutral' and wait for 5 seconds.
  8. Perform sub-steps  6 and  7 a total of five times.
