Automatic transmissions are one of the most expensive components to repair or replace—but many transmission problems are preventable with proper care and driving habits. At Sergeant Clutch Discount Transmission Repair Shop in San Antonio, we’ve put together a Top 10 List of Do’s and Don’ts to help you protect your transmission and avoid costly repairs.

Top 10 Transmission Do’s & Don’ts
1. Do follow your vehicle’s scheduled maintenance and change transmission fluid as recommended in your owner’s manual.

2. Do have your transmission fluid checked regularly—ideally every time you change your engine oil.

3. Do come to a complete stop before shifting from reverse to drive or vice versa.

4. Don’t drive on a spare or mismatched tires (especially on FWD or AWD vehicles) for extended periods—this can cause transmission damage.

5. Don’t drive your vehicle with low or no transmission fluid—this can lead to overheating and severe internal damage.

6. Don’t shift from drive to reverse (or reverse to drive) while the vehicle is still moving.

7. Don’t spin your tires on turns, especially in front-wheel-drive vehicles—this stresses the differential and transmission.

8. Don’t continue driving if your transmission is slipping, making noises, or shifting abnormally—get it inspected immediately.

9. Don’t drag race unless your transmission has been professionally modified for high performance—it puts excessive strain on the system.

10. Don’t use 4x4 mode on dry pavement unless your vehicle is AWD or equipped with automatic 4WD—it can bind up the drivetrain.

Expert Tip from Sergeant Clutch: Routine preventive transmission maintenance is the best way to extend the life of your transmission. Even simple habits—like pausing before shifting gears or checking fluid levels—can save you thousands in repairs.
