Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
With the vehicle running, pull the dipstick and wipe it clean.
Reinsert the dipstick and remove again to check the fluid level.
If fluid is low, add the recommended type of transmission fluid until it reaches the proper level.
If fluid is burnt or discolored, drain and replace the transmission fluid using a fluid pump.
Torque the transmission pan bolts to manufacturer specifications (usually 10-12 ft-lbs).

3. Inspect and Replace Torque Converter (if necessary)

Tools Required: Jack, jack stands, socket set, torque wrench.
Raise the vehicle and support it securely on jack stands.
Remove the transmission pan to access the torque converter.
Disconnect the torque converter from the engine flexplate and the transmission.
Replace with a new torque converter, ensuring it is properly seated.
Reassemble the transmission pan and refill with fresh transmission fluid.

4. Reconnect Battery

Reattach the battery terminals and ensure they are tight.
Start the vehicle and allow it to idle for a few minutes.
