Your transmission is the link between engine power and the wheels. When it shifts hard, slips, leaks fluid, or makes new noises, you need clear diagnostics and the right transmission services, not guesswork. At Auto Craft Garage we provide professional transmission repair, automatic transmission repair, transmission fluid change and flush, transmission rebuild and transmission replacement when needed, plus clutch repair for manual drivetrains.
What We Service
- Transmission inspection and road test for shift quality, noises, and vibration under load.
- Transmission fluid change, automatic transmission fluid change, and transmission filter change where the design allows.
- Transmission flush or transmission fluid exchange for units that benefit from full fluid replacement.
- Transmission fluid leak repair, pan gasket and seal replacement, and cooler line service.
- Automatic transmission repair including solenoids, valve body issues, and electronics.
- Transmission rebuild or transmission replacement when internal wear or damage is beyond minor repair.
- Clutch repair and hydraulic service for manual transmissions.

Transmission Diagnostics Before Repairs
Electronic Diagnostics
Modern units rely on sensors, solenoids, and a transmission control module. Our technicians perform a structured diagnostic test that can include:
- Scan tool checks for transmission codes and live data from shift solenoids, speed sensors, and pressure sensors.
- Verification that the transmission control module commands match what the unit does on the road.
- Temperature data review to see how heat may be affecting fluid and internal parts.
Mechanical Checks
We combine data with under vehicle inspection and a proper road test:
- Visual transmission inspection for leaks, pan condition, mounts, and axles.
- Transmission fluid check where possible for level, color, and smell.
- Pan and filter inspection during a transmission fluid change to look for excessive debris.
- Mount checks so a worn mount is not mistaken for an internal failure.
Fluid Services Done the Right Way
Not every vehicle needs the same approach. Some transmissions are designed for a simple drain and fill, others allow pan removal and filter replacement, and some sealed designs require specific procedures. We will:
- Use the correct transmission lubricant or ATF type that your manufacturer specifies, including CVT and dual clutch applications.
- Explain the difference between a transmission fluid change and a transmission flush so you understand the method we recommend.
- Replace the filter and pan gasket when the design allows and it makes sense for the mileage.
- Check for leaks after service and verify the fluid level at the proper temperature and procedure.
If your visit also reveals due engine maintenance, we can coordinate with Oil Change and Maintenance so you leave with both services up to date.
Repair, Rebuild, or Replace
Some problems can be solved with targeted transmission repair, while others point to deeper wear. Our goal is to match the repair level to the real condition of your unit.
- Serviceable repairs: solenoid and sensor replacement, valve body service, transmission fluid leak repair, mount replacement, and external wiring repairs.
- Transmission rebuild: internal clutches, bands, bushings, and hard parts replaced and clearances reset in a controlled environment.
- Transmission replacement: quality remanufactured or replacement units installed when internal damage is severe or the case is compromised.
We will explain what we find in plain language, show photos of parts when helpful, and compare options before you decide which path to take.
Clutch and Manual Transmission Services
Manual and some automated manual units rely on a clutch to connect and disconnect power. Worn clutches can slip, chatter, or make it hard to select gears. Our drivetrain services include:
- Clutch repair and replacement with the right disc, pressure plate, and release bearing for your vehicle.
- Flywheel inspection and resurfacing or replacement when needed.
- Hydraulic work such as clutch master cylinder repair and slave cylinder service.
- Fluid service for compatible manual transmissions and transaxles.
Common Symptoms and Likely Services
| Symptom | What we look at first |
|---|---|
| Delayed engagement when shifting into drive or reverse | Fluid level and condition, line pressure, possible internal wear or valve body issues |
| Harsh shifts or erratic shifting | Scan for codes, solenoids, valve body, mounts, and updated software for the control module |
| Transmission slipping under load | Fluid condition, internal clutch wear, cooler operation, and potential transmission rebuild needs |
| Red fluid on the driveway | Transmission fluid leak repair at pan gasket, cooler lines, axle seals, or front and rear seals |
| Whine or growl that changes with vehicle speed | Fluid level, bearings, differential section, and sometimes rear differential service |
| Clutch pedal high, slipping, or hard to shift gears | Clutch repair, hydraulic inspection, and linkage checks |

FAQ
Quick answers about transmission fluid, repairs, and when a rebuild makes sense.
It depends on design and condition. Some units are best served by a simple transmission fluid change with pan removal and filter replacement. Others benefit from a controlled transmission flush that exchanges more of the old fluid. We inspect the unit, check the manual, and explain which method fits your transmission.
Intervals vary a lot. Some manufacturers suggest around 30,000 to 60,000 miles, others list longer intervals, and some CVT and dual clutch units have special rules. The best practice is to follow the service schedule in your owner manual and adjust for heavy use like towing or city traffic. We can review the schedule with you.
There are myths that fluid service always causes failures on high mileage units. In reality, problems usually come from pre existing wear. We evaluate how the transmission behaves, check fluid condition, and then explain the benefits and risks of fluid service so you can make an informed choice.
We service many CVT units, including correct fluid service and basic cvt repair related diagnostics. Because CVT designs are sensitive to fluid type and level, we only use manufacturer specified fluids and procedures. For severe internal damage we may recommend a specialized transmission rebuild or replacement option.
If the transmission will not move the car, slips badly, makes loud grinding noises, or loses a large amount of fluid, it is safer to stop and request towing instead of forcing it to drive. We can coordinate with our towing service to bring the car in without extra damage.
If the case and hard parts are in good shape, a transmission rebuild can restore performance and keep your original unit with updated components. If there is case damage, severe wear, or limited parts availability, a quality transmission replacement or remanufactured unit may be a better long term solution. We compare options and help you choose.
