Transmission Service & Rebuilds

Warning signs include slipping between gears (engine revs but vehicle doesn't accelerate), hard or delayed shifts, grinding or shaking during gear changes, burning smell from transmission fluid, fluid leaks (red or brown fluid under your vehicle), the transmission warning light, or the vehicle not engaging in gear. If you notice any of these, avoid driving aggressively and schedule a diagnostic soon—early intervention can save the transmission.

Intervals vary by vehicle and transmission type. Most automatic transmissions benefit from fluid exchange every 30,000–60,000 miles. CVTs typically need service every 30,000–45,000 miles. Some manufacturers claim 'lifetime' fluid, but this assumes ideal conditions—Austin's heat and stop-and-go traffic qualify as severe duty. We recommend checking fluid condition regularly and servicing based on your specific vehicle's needs and driving conditions.

Many transmission problems are caused by a single failed component—a solenoid, sensor, valve body issue, or worn seal—rather than widespread internal damage. Proper diagnosis determines the scope. We perform thorough diagnostics including electronic scans, road testing, and fluid analysis before recommending any major work. We'll never sell you a rebuild if a component repair will resolve the issue reliably.

A fluid exchange (drain and fill) removes approximately 40–60% of old fluid and replaces it with fresh fluid—this is the gentler, more common approach. A flush uses a machine to push all old fluid out under pressure, replacing nearly 100%. Not all transmissions should be flushed, especially high-mileage units that have never been serviced—the pressure can dislodge debris and cause problems. We recommend the appropriate method based on your vehicle's service history and condition.
