Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Sub-steps:
- Locate the transmission dipstick and remove it to check fluid level.
- If fluid is low or dirty (dark brown or burnt smell), drain the transmission fluid using a drain pan.
- Replace with manufacturer-recommended transmission fluid (consult owner's manual for specifications).
- Refill the transmission fluid through the dipstick tube, ensuring the level is correct.

3. Replace Transmission Filter

Sub-steps:
- Remove the transmission pan by loosening the bolts, allowing any remaining fluid to drain.
- Remove the old transmission filter and replace it with a new one.
- Clean the transmission pan and replace the gasket before re-installing the pan.

4. Inspect and Replace Transmission Solenoids (if necessary)

Sub-steps:
- Access the solenoids by removing the transmission pan or valve body as needed.
- Disconnect the wiring harness from the solenoid and remove it from its mounting.
- Replace with new solenoids, ensuring proper alignment and connection.

5. Reconnect Battery and Conduct Final Checks

Reconnect the battery and clear any diagnostic trouble codes (DTCs).
Start the engine and cycle through the gears to verify smooth operation.
