Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety during repairs.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, transmission fluid pump
Remove the transmission dipstick and check the fluid level. If low, add the correct type of transmission fluid as specified in the owner’s manual.
If the fluid appears burnt or contaminated, drain the old fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan.
- Allow the old fluid to fully drain.
Replace the filter by removing any retaining clips or screws, then install the new filter securely.

3. Inspect and Replace Transmission Solenoids

Tools Required: Socket set, torque wrench, multimeter
Remove the transmission pan again if it was previously removed.
Locate the solenoids and disconnect their electrical connectors.
Use a multimeter to test each solenoid for resistance; replace any faulty solenoids.
Reinstall the new or tested solenoids and reconnect the electrical connectors.

4. Reassemble and Refill

Reinstall the transmission pan using a new gasket.
Torque the pan bolts to the manufacturer's specification (consult service manual for exact values).
Refill the transmission with the appropriate amount of new fluid using a funnel.

5. Final Checks

Reconnect the battery.
Start the engine and allow it to warm up while checking for any leaks around the transmission pan and cooler.
Check the fluid level again and top off if necessary.
