Solution

1. Preparation

Gather tools and parts required for the repair.
Park vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean and reinsert it to check fluid level.
3. If the fluid is low, add the manufacturer-recommended transmission fluid as needed.
