Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting.
Disconnect the battery to avoid electrical issues during the repair.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level; if low, add the manufacturer-recommended transmission fluid.
3. If the fluid is dirty or burnt, drain the existing fluid using a fluid pump.
4. Replace the transmission fluid with new fluid, filling it to the proper level.
5. Recheck the level after running the vehicle for a few minutes.

3. Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unbolting it from the transmission housing.
2. Carefully clean the mating surfaces of the pan and housing.
3. Remove the old filter and install a new filter, ensuring it is seated correctly.
4. Reinstall the transmission pan with a new gasket, torqueing the bolts to manufacturer specifications.

4. Reconnect Battery and Test

Sub-steps:
1. Reconnect the battery and ensure all electrical connections are secure.
2. Start the vehicle and allow it to reach operating temperature.
3. Test drive the vehicle to confirm that the jerking during shifting has been resolved.
