Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts while working.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Remove any components obstructing access to the belts (if necessary).
2. Check the drive belts for fraying, cracking, or misalignment.
3. If damaged, remove the old belt by loosening the tensioner pulley with a socket set.
4. Install the new belt, ensuring it is properly seated on all pulleys.
5. Re-tension the belt according to manufacturer specifications.

3. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel and tire assembly to access the brakes.
2. Inspect brake pads for excessive wear; replace if less than 1/8 inch thick.
3. Check rotors for scoring or warping; machine or replace if necessary.
4. Reassemble the brake components and wheel, ensuring all bolts are torqued to specifications.

4. Transmission Fluid Check and Replacement

Sub-steps:
1. Place a drain pan under the transmission pan.
2. Remove the transmission fluid pan bolts and carefully lower the pan to drain fluid.
3. Inspect the pan for metal shavings; clean the pan and replace the filter if necessary.
4. Reinstall the pan and refill the transmission with the correct type of fluid as specified by the manufacturer.
