Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues during repairs.

2. Check and Change Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick (if applicable) and check the fluid level.
2. If the fluid is low, add the manufacturer-recommended transmission fluid.
3. If the fluid is discolored or burnt, drain the old fluid using a drain pan.
4. Replace the transmission filter if applicable.
5. Refill with new, manufacturer-recommended transmission fluid to the correct level.

Tools Required:

OBD-II scanner
Socket set
Drain pan
Funnel

3. Inspect and Replace Shift Solenoids
