Repair Time
4-8 hours

Safety Warnings

  • ⚠Disconnect the battery before working on electrical systems.
  • ⚠Allow engine to cool before opening the transmission fluid pan.

Symptoms

  • •Engine stalling or hesitation during acceleration
  • •Slipping or delayed engagement when shifting from park to drive
  • •Unusual noises such as whining or grinding from the transmission area
  • •Poor fuel economy compared to previous performance
  • •Overheating transmission fluid
  • •Check engine light illuminated with transmission-related error codes

Diagnostic Steps

  1. 1Scan the vehicle's OBD-II system for any error codes related to the transmission or torque converter.
  2. 2Inspect the transmission fluid level and condition; look for signs of contamination or burning smell.
  3. 3Conduct a stall test by pressing the brake, shifting to drive, and gradually applying throttle to observe RPM behavior.
  4. 4Listen for unusual noises while the vehicle is in gear and accelerating, which could indicate torque converter issues.
  5. 5Check the performance of the torque converter lock-up function during highway driving; it should engage smoothly.
  6. 6Test the vehicle's acceleration; if there is a noticeable lag or slipping sensation, this may indicate torque converter failure.

Solution

Solution

1. Preparation

  • Gather tools and materials.
  • Ensure the vehicle is parked on a level surface, and the engine is off.
  • Disconnect the battery to prevent electrical shorts.

2. Remove Transmission Fluid

  • Replace the transmission filter if applicable.

3. Remove Torque Converter

  • Disconnect any wiring harnesses attached to the torque converter.
  • Remove the inspection cover to access the torque converter bolts.
  • Use a socket set to remove the torque converter bolts from the flexplate.
  • Carefully slide the torque converter off the input shaft and out of the transmission.

4. Inspect and Replace

  • Inspect the torque converter for signs of damage, such as cracks or excessive wear.
  • Compare the old torque converter to the new one to ensure compatibility.
  • Install the new torque converter by sliding it onto the input shaft and aligning it with the flexplate.

5. Reassemble Components

  • Reattach the transmission fluid pan, ensuring a new gasket is used if necessary.
  • Refill the transmission with the correct type and amount of fluid as specified in the owner’s manual.
  • Reconnect the battery.

6. Test Drive
