Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during work.

2. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and then remove it again to check the fluid level.
If low, add the specified transmission fluid (refer to the owner’s manual for type and specification).
If the fluid is burnt or contaminated, proceed to fluid replacement.

3. Replace Transmission Fluid (if necessary)

Drain the old transmission fluid by locating the drain plug and removing it.
Allow the fluid to completely drain into a suitable container.
Replace the drain plug and torque it to manufacturer specifications.
Refill with new transmission fluid through the dipstick tube, using a funnel. Ensure it’s filled to the correct level.

4. Inspect and Clean TCM Connections

Locate the transmission control module and disconnect the electrical connectors.
Inspect for corrosion or damage on the connectors.
Clean the connectors with electrical contact cleaner and allow to dry before reconnecting.

5. Test Drive

Reconnect the battery and start the engine.
Take the vehicle for a test drive to ensure that the jerking issue has been resolved.
