Fast Filling Adaptation Procedure

WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.

Perform the following procedure when the TCM or TCMA, or Transmission assembly (with TCMA) has been replaced, or when the adaptation values have been reset. This procedure should be performed before performing the Standard Clutch Filling Adaptation Procedure when these components are replaced.

NOTE:

Perform this procedure on a smooth road surface. The TCM or TCMA will abort the adaptation process if it senses rough road conditions. The road should be clear of traffic due to the start, stop, and slow vehicle speeds required during this procedure.

  1. With the Scan Tool, erase DTCs.
  2. Setup the scan tool to display the Transmission Oil Temperature, Torque, Turbine (Input) Speed Sensor RPM, and Clutch 'X' - Filling Counter for each clutch.
  3. Drive the vehicle until the Transmission Oil Temperature is above 30° C (86° F).
  4. Stop the vehicle.
  5. Drive the vehicle to perform upshifts for all gears under the following conditions:
    • Light to medium throttle position
    • Turbine (Input) Speed between 1, 250 - 2, 000 RPM
    • Torque between 100 N.m and 150 N.m (74 ft. lbs. and 111 ft. lbs.)
  6. Release the throttle (0% position) to coast and allow a 6-5 down-shift.
  7. Perform steps 4-6 until the Filling Counters for each clutch displays 10 counts.

    The tables below may be used as an alternate reference for the optimal conditions required to learn the Fast Filling Adaptations.

    FAST FILLING ADAPTATION CONDITIONS TABLE

    Conditions Where Fast Filling Adaptations Occur
    Condition Transmission Temperature Torque N.m (ft. lbs.) Input Speed (RPM)
    Upshifts Between 30° C and 100° C (86° F and 212° F) Between 100 N.m and 150 N.m (74 ft. lbs. and 111 ft. lbs.) Between 1250 and 2000 RPM
    6-5 Downshifts for B Clutch Between 30° C and 100° C (86° F and 212° F) Between negative (-) 60 N.m and negative (-) 40 N.m (negative (-) 44 ft. lbs. and negative (-) 30 ft. lbs.) Between 750 and 1100 RPM
    CLUTCH VS SHIFT TABLE

    Shifts Where Each Clutch Will Fast Adapt
      A Clutch B Clutch C Clutch D Clutch E Clutch
    Shift  6 - 7 6 - 5 2 - 3 and 4 - 5 3 - 4 1 - 2 and 5 - 6
    Optimal conditions under which adaptation learning occurs.  Best performed at highway speeds in excess of 80 kph (50 mph). Coasting with throttle at 0% position. Best performed at light to medium-throttle - normal vehicle launch. Best performed at light to medium-throttle - normal vehicle launch. Best performed at light to medium-throttle - normal vehicle launch.
  8. Perform the Standard Clutch Filling Adaptation Procedure.
