Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface with the engine off.
Required tools: OBD-II scanner, socket set, torque wrench, transmission fluid pump.

2. Inspect and Replace Transmission Fluid

Check Fluid Level: Remove the dipstick and check the fluid level against the specified range.
Fluid Condition: Inspect the fluid for discoloration or burnt smell.
Fluid Change: If necessary, drain the old transmission fluid and replace with the manufacturer-recommended fluid. Use a transmission fluid pump for refilling.
- Tools: Transmission fluid pump, socket set.
- Torque Specifications: Follow the manufacturer’s specifications for any transmission pan bolts when reassembling.

3. Torque Converter Inspection

Remove Transmission Access Cover: If applicable, to access the torque converter.
Check for Damage: Inspect the torque converter for signs of wear, such as cracks or signs of overheating.
Test the Lock-up Mechanism: Use a scan tool to engage and disengage the lock-up function. If it does not operate correctly, consider replacement.
Replacement: If faulty, remove the torque converter and replace it with a new unit, following torque specifications for attachment.

4. Test Drive

After repairs, conduct a test drive under various conditions to ensure the issue is resolved.
