Diagnostic Steps

  1. 1Scan the vehicle's onboard computer using an OBD-II scanner for any error codes.
  2. 2Check transmission fluid level and condition; look for discoloration or burnt smell.
  3. 3Inspect the transmission control module (TCM) for any signs of damage or corrosion.
  4. 4Test the throttle position sensor (TPS) and make sure it's functioning within specifications.
  5. 5Examine transmission mounts for wear or damage that could affect alignment.
  6. 6Perform a road test to replicate the jerking issue and note conditions that trigger it.

Solution

Solution

1. Fluid Inspection and Replacement

  • Sub-steps:
    1. Raise the vehicle securely on jack stands.
    2. Remove the transmission dipstick and check fluid level and condition.
    3. If fluid is low or discolored, drain the old fluid using a suitable container.
    4. Replace the transmission filter if applicable.
    5. Refill with manufacturer-recommended transmission fluid (consult owner’s manual for specifications).

2. Transmission Control Module (TCM) Reprogramming

  • Sub-steps:
    1. Connect the vehicle to a diagnostic scanner that supports TCM programming.
    2. Follow the prompts to reset or reprogram the TCM.
    3. Clear any existing error codes and turn off the engine.
    4. Restart the vehicle and check for normal shifting behavior.

3. Throttle Position Sensor (TPS) Adjustment/Replacement

  • Sub-steps:
    1. Disconnect the battery (negative terminal first).
    2. Locate the TPS on the throttle body and disconnect the electrical connector.
    3. Use a multimeter to test the TPS resistance according to service specifications.
    4. If faulty, remove the TPS using a screwdriver and replace it with a new one.
    5. Reconnect the electrical connector and the battery.

4. Inspect and Replace Transmission Mounts

  • Sub-steps:
    1. Raise the vehicle and securely support it with jack stands.
    2. Inspect the transmission mounts for cracks or excessive wear.
    3. If damaged, remove the old mounts using a socket set.
    4. Install new mounts, tightening to the manufacturer’s specified torque values.
