Solution

1. Preparation

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

2. Check Transmission Fluid

Tools Required: Transmission fluid pump, funnel.
Remove the transmission dipstick and wipe clean.
Insert the dipstick back into the tube and pull it out again.
Check fluid level; if low, add the recommended transmission fluid type as per the manufacturer’s specifications.
Inspect fluid condition; if burnt or contaminated, a fluid change is necessary.

3. Replace Transmission Filter

Tools Required: Socket set, transmission filter kit.
Remove the transmission pan by unscrewing all bolts.
Carefully lower the pan and drain the old fluid into a suitable container.
Remove and replace the old filter with a new one.
Clean the pan and magnetic pickup, then reattach the pan with a new gasket.

4. Test Transmission Components

Tools Required: Multimeter.
Check the transmission range sensor by measuring resistance and comparing it with specifications.
If faulty, replace the sensor and reconnect the wiring.

5. Refill Transmission Fluid

Using the transmission fluid pump, refill the transmission with the proper type and quantity of fluid.
Start the engine and cycle through the gears while monitoring fluid levels, adding more if necessary.
