Solution

1. Preparation

Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
Remove the transmission drain plug and drain the old fluid into a clean container.
Replace the drain plug and torque it to manufacturer specifications.
Refill with the appropriate type of transmission fluid as indicated in the owner's manual using a funnel.

3. Replace Transmission Filter

Tools Required: Socket set, screwdrivers, gasket scraper.
Remove the transmission pan by unscrewing the bolts and carefully prying it off.
Remove the old filter and replace it with a new filter.
Clean the pan and replace the gasket before reinstalling the pan.
Torque the pan bolts to the specified value.

4. Test and Replace Transmission Solenoids (if necessary)

Tools Required: Multimeter, socket set.
Disconnect the electrical connectors from the solenoids and test each solenoid with a multimeter for resistance.
If any solenoids are faulty, remove and replace them.
Reconnect all electrical connectors and ensure they are secure.
