Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Funnel, transmission fluid pump, fluid catch pan.
Remove the transmission dipstick and check fluid level; if low, add the recommended type of transmission fluid (consult owner’s manual for specifications).
If fluid is dark or has a burnt odor, proceed to change the fluid.
Drain the old transmission fluid into a catch pan by removing the drain plug.
Replace the transmission filter:
- Remove the transmission pan bolts with a socket set.
- Carefully detach the pan and clean it along with the magnet inside.
- Replace the old filter with a new one and secure it in place.
Reinstall the transmission pan with a new gasket, ensuring to torque the bolts to manufacturer specifications.

3. Inspect and Replace Transmission Components (if needed)

Tools Required: Socket set, torque wrench, screwdrivers.
Inspect the transmission for any damaged components such as solenoids or bands.
Replace any faulty solenoids or bands according to the manufacturer's repair manual.
Reassemble any components removed during inspection.

4. Refill Transmission Fluid

Use a funnel to refill the transmission with fresh fluid through the dipstick tube.
Start the engine and let it idle, then shift through all gears to circulate fluid.
Check the fluid level again with the dipstick and add more if necessary.
