Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Allow the engine to cool if it has been running.

2. Check and Replace Transmission Fluid

Raise the vehicle using a jack and secure it with jack stands.
Locate the transmission dipstick (if equipped) or the fill plug on the transmission.
Remove the dipstick or fill plug and check the fluid level and condition.
If the fluid is low or contaminated, drain the old transmission fluid:
- Place a drain pan under the transmission.
- Remove the drain plug and allow the fluid to drain completely.
Replace the drain plug and torque it to the manufacturer’s specifications.
Refill the transmission with the correct type of fluid (refer to the owner's manual for specifications).
Start the engine and allow it to reach operating temperature; recheck the fluid level and add as necessary.

3. Inspect Torque Converter

If fluid replacement does not resolve the shudder, inspect the torque converter.
Remove the transmission inspection cover if necessary.
Check the torque converter for any signs of wear, damage, or contamination.
If issues are found, replace the torque converter:
- Disconnect the battery and remove any components obstructing access to the transmission.
- Remove the transmission from the engine (follow proper disassembly procedures).
- Replace the torque converter and reassemble the transmission.
- Reconnect any components removed during disassembly.
