Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, transmission fluid, differential fluid, and safety glasses.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Transmission Fluid Change

Drain Old Fluid:
- Locate the transmission fluid drain plug and place a drain pan underneath.
- Remove the drain plug and allow the fluid to fully drain.
- Replace the drain plug and torque it to manufacturer specifications (typically 15-20 ft-lbs).
Refill with New Fluid:
- Use a funnel to add the appropriate type of transmission fluid (refer to the owner's manual for specifications).
- Start the engine and allow it to run for a few minutes to circulate the new fluid.
- Recheck the fluid level and add more if necessary.

3. Drive Belt Replacement (if necessary)

Remove the Old Belt:
- Locate the tensioner and use a socket wrench to relieve tension on the belt.
- Remove the belt from the pulleys.
Install New Belt:
- Route the new belt according to the belt routing diagram (usually found on a sticker in the engine bay).
- Reapply tension using the tensioner and ensure the belt is seated correctly on all pulleys.

4. Differential Fluid Change (if necessary)

Drain Old Differential Fluid:
- Locate the differential drain plug and place a pan underneath.
- Remove the drain plug and allow the fluid to fully drain.
- Replace the drain plug and torque it to the specified value (typically around 30 ft-lbs).
Refill Differential:
- Remove the fill plug and use a fluid pump to add new differential fluid until it reaches the fill level.
- Replace the fill plug and torque it to specifications.
