Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Funnel, clean rag.
Remove the transmission dipstick and wipe it clean with a rag.
Reinsert dipstick and remove again to check fluid level; add fluid if necessary.
Inspect fluid condition; if burnt or dirty, proceed to fluid change.

3. Change Transmission Fluid and Filter

Tools Required: Socket set, transmission filter kit, drain pan.
Place a drain pan under the transmission pan and remove the pan bolts.
Carefully lower the pan and drain the old fluid.
Remove the old filter and install the new filter from the kit.
Clean the transmission pan and replace the gasket.
Reattach the pan with the specified torque (check service manual for torque specifications).
Fill the transmission with new, manufacturer-recommended fluid using a funnel.

4. Inspect and Replace Components

Inspect transmission mounts; replace if cracked or sagging.
Check the throttle position sensor and vehicle speed sensor for functionality; replace if necessary.

5. Reconnect Battery and Test Drive

Reconnect the battery and start the engine.
Conduct a test drive to ensure smooth shifting and confirm jerking issue is resolved.
