Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent electrical shorts during work.

2. Check Transmission Fluid

Tools Required: Transmission fluid dipstick or funnel, shop towels.
Remove the dipstick to check fluid level; add fluid if low.
If fluid is burnt or contaminated, proceed to change the fluid and filter.

3. Change Transmission Fluid and Filter

Tools Required: Socket set, fluid pump, drain pan.
Sub-steps:
1. Place the drain pan under the transmission pan.
2. Remove the transmission pan bolts and carefully lower the pan to drain fluid.
3. Remove the old filter and replace it with a new one.
4. Clean the pan and re-install it with a new gasket, tightening bolts to the manufacturer's torque specification.
5. Refill the transmission with the correct type and amount of fluid as specified in the owner's manual.

4. Inspect and Replace Transmission Solenoids (if necessary)

Tools Required: Socket set, multimeter.
Remove the transmission cover to access the solenoids.
Use a multimeter to test the solenoid resistance; replace any faulty solenoids.
Reassemble the transmission cover and ensure all seals are intact.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals securely.
Start the engine and allow it to reach normal operating temperature.
Test drive the vehicle to ensure that the slipping issue is resolved.
