Solution

Solution

1. Preparation

  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and securely supported with jack stands.
  • Disconnect the battery to prevent electrical issues.

2. Check Transmission Fluid

  • Locate the transmission dipstick and remove it.
  • Wipe it clean, reinsert it, and pull it out again to check the fluid level.
  • If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.

3. Inspect Torque Converter

  • Remove the transmission access cover if necessary.
  • Visually inspect the torque converter for signs of damage, such as cracks or leaks.
  • Check the condition of the torque converter mounting bolts; ensure they are tight and free of debris.

4. Replace Torque Converter (if necessary)

  • Tools Required: Socket set, torque wrench, transmission jack, fluid catch pan.
  • Remove the driveshaft or axle (if applicable).
  • Unbolt the torque converter from the flywheel/flexplate using the socket set.
  • Lower the transmission slightly using the transmission jack and disconnect the torque converter from the transmission input shaft.
  • Install the new torque converter by reversing the removal steps and ensuring it is fully seated on the input shaft.
  • Torque the converter bolts to the manufacturer specifications (usually around 36 Nm or 26 lb-ft).

5. Refill Transmission Fluid

  • After reassembling, refill the transmission with the appropriate fluid type as specified in the owner’s manual.
  • Start the engine and allow it to warm up, then check the fluid level again and adjust as necessary.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
