Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, rags for spills.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before beginning work.

2. Change Transmission Fluid

Drain Old Fluid:
- Remove the transmission drain plug using a socket set.
- Allow the old fluid to completely drain into a pan.
Replace Transmission Filter (if applicable):
- Remove the transmission pan (if accessible) using a socket set.
- Replace the old filter with a new one.
Refill with New Fluid:
- Reinstall the transmission pan and torque the bolts to the specified value (consult the service manual for specific torque specs).
- Using a funnel, refill the transmission with the appropriate type and amount of new transmission fluid.

3. Inspect and Replace Components

Check Solenoids:
- If any solenoids were found defective during the diagnostic step, remove and replace them with new units.
Replace Transmission Mounts:
- If mounts are damaged, support the transmission and remove the old mounts.
- Install new mounts and ensure they are properly torqued.
Test Drive:
- After completing the fluid change and any component replacements, perform a test drive to ensure smooth shifting.
