Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Fluid Change

Drain the Transmission Fluid
- Locate the transmission drain plug and position a drain pan beneath it.
- Remove the drain plug and allow the fluid to completely drain.
- Replace the drain plug with a new gasket and torque it to the manufacturer’s specifications.
Replace Transmission Filter (if applicable)
- Remove the transmission pan by loosening the bolts and carefully separating it from the transmission case.
- Remove the old filter and replace it with a new one, ensuring it is properly seated.
Refill with New Fluid
- Use the manufacturer's specified transmission fluid type.
- Pour the new fluid through the dipstick tube or designated fill port until it reaches the correct level.

3. Inspect and Replace Transmission Solenoids

Remove the Transmission Pan Again (if needed)
- Follow the same steps as above to access the solenoids.
Access the Solenoids
- Disconnect the wiring harness from the solenoids.
- Remove the retaining bolts and take out the faulty solenoids.
Install New Solenoids
- Position the new solenoids and secure them with bolts.
- Reconnect the wiring harness.

4. Test Drive

Reconnect the battery.
Start the engine and allow it to warm up.
Conduct a test drive to ensure the transmission engages smoothly and no slipping occurs.
