Delayed Or Rough Shifting

Your transmission hesitates when changing gears, shifts harshly between gears, or refuses to shift at certain speeds. These symptoms indicate low fluid levels, worn clutch packs, or valve body problems requiring immediate attention before complete transmission failure.

Slipping Gears Or Loss Of Power

Your vehicle unexpectedly changes gears while driving or the engine revs without corresponding acceleration. Slipping transmissions indicate worn friction materials, low fluid pressure, or internal component failures that worsen rapidly without repair.

Transmission Fluid Leaks

Red or brown fluid appears under your vehicle after parking, indicating transmission seal failures or pan gasket leaks. Fluid loss causes inadequate lubrication and cooling, leading to rapid transmission damage and expensive rebuilds if not addressed promptly.

Transmission Fluid Exchange

Complete Fluid Replacement For Optimal Performance

Transmission fluid lubricates moving parts, cools components, and provides hydraulic pressure for gear changes. Over time, fluid breaks down from heat, becomes contaminated with friction material, and loses protective additives. Our fluid exchange service removes old contaminated fluid and replaces it with fresh fluid meeting your vehicle’s specifications.

Unlike older flush methods that could damage transmissions, modern exchange processes replace fluid gradually during normal transmission operation. We use manufacturer-specified fluids whether conventional, synthetic, or CVT-specific formulations. Arizona’s heat accelerates fluid deterioration, making regular exchange important preventive maintenance. Fresh fluid maintains proper hydraulic pressure, reduces operating temperatures, and extends transmission life by preventing wear from contaminated fluid.

Transmission Filter Replacement

Removing Contaminants From Your Transmission

Internal transmission filters trap metal particles, clutch material, and debris preventing contamination from damaging precision components. Some vehicles use external spin-on filters easily accessed, while others require pan removal for internal filter service. Clogged filters restrict fluid flow reducing hydraulic pressure and causing shift problems.

During pan service, we inspect filters for excessive metal particles indicating internal wear. Filter replacement includes new pan gaskets preventing leaks and proper fluid refill with bleeding procedures removing air pockets. Not all transmissions have serviceable filters—some use permanent internal screens not designed for replacement. We identify your transmission’s filter type and recommend appropriate service intervals based on manufacturer specifications and fluid condition.

Transmission Pan Service

Thorough Inspection And Cleaning

Removing the transmission pan provides direct access to internal components, filters, and accumulated debris in the pan bottom. Pan service reveals transmission condition through metal particle inspection—fine aluminum dust is normal, while chunks or excessive material indicate problems.

We clean the pan thoroughly, inspect the magnet that captures metal particles, and install new gaskets using proper sealant and torque specifications. Pan removal also allows solenoid inspection and replacement when necessary. This comprehensive service provides more thorough fluid exchange than simple drain-and-fill because it accesses fluid trapped in the valve body. Pan service costs more than basic fluid exchange but provides superior maintenance and diagnostic information about internal transmission condition.

Transmission Leak Repair

Stopping Fluid Loss Before Damage Occurs

Transmission leaks develop at pan gaskets, output shaft seals, input shaft seals, cooler lines, or the torque converter seal behind the engine. Low fluid from leaks causes inadequate lubrication, overheating, and rapid transmission damage. We locate leaks through visual inspection, pressure testing, and UV dye when necessary.

Some leaks require simple gasket replacement, while others need seal service involving transmission removal for access. Cooler line leaks at connections can often be repaired by replacing O-rings or tightening fittings. We assess leak severity and repair complexity, providing honest recommendations about whether repairs make sense given transmission age and condition. Minor leaks caught early prevent expensive damage from low fluid levels.

Transmission Solenoid Replacement

Restoring Electronic Shift Control

Modern transmissions use electronic solenoids controlling hydraulic fluid flow for gear changes. Solenoids fail from electrical problems, internal wear, or contamination, causing harsh shifts, delayed engagement, or check engine lights with transmission codes.

Our scan tools show us exactly what’s happening in real-time—whether it’s the solenoid itself, a wiring issue, or a computer glitch. We test, we verify, and we fix the actual problem rather than throwing parts at your transmission hoping something works. Many solenoids are accessible through the pan for replacement without transmission removal, though some require extensive disassembly. Solenoid replacement includes new seals, proper torque specifications, and transmission relearn procedures teaching the computer new solenoid characteristics. Failed solenoids often result from contaminated fluid, so we recommend fluid service when replacing solenoids to prevent repeat failures.

Transmission Sensor Service

Maintaining Accurate Computer Control

Transmissions use multiple sensors providing data for computer-controlled shift timing. Speed sensors measure input and output shaft rotation determining gear ratios and vehicle speed. Temperature sensors monitor fluid heat affecting shift firmness and torque converter lockup. Pressure sensors measure hydraulic pressure verifying proper operation.

Failed sensors cause check engine lights, erratic shifting, or transmissions stuck in one gear (limp mode). We test sensors using scan tools monitoring live data, checking electrical connections, and verifying proper sensor output. Sensor replacement often provides inexpensive fixes for transmission problems that seem serious. External sensors are easily accessible, while some internal sensors require transmission disassembly for replacement.

Clutch Service (Manual Transmissions)

Manual Transmission Clutch Maintenance

Manual transmissions use clutches connecting the engine to transmission input shaft, allowing gear changes without stopping the engine. Clutches wear from normal use, eventually requiring replacement when material thickness reaches minimum specifications. Symptoms include slipping during acceleration, difficulty shifting gears, or chattering during engagement.

Clutch service includes inspecting the clutch disc, pressure plate, and release bearing, replacing worn components, and resurfacing or replacing the flywheel if damaged. We also inspect hydraulic clutch systems on modern vehicles, checking master and slave cylinders for leaks or weak operation. Proper clutch adjustment ensures optimal pedal feel and engagement. Arizona traffic increases clutch wear through frequent starts and stops, making periodic inspection valuable for manual transmission vehicles.

Differential Service

Maintaining Rear And All-Wheel Drive Systems

Differentials distribute power to drive wheels, requiring dedicated lubricant separate from transmission fluid. Rear-wheel and all-wheel drive vehicles have differentials needing periodic service. Differential fluid breaks down from heat and contamination, losing lubrication properties and causing gear wear.

We drain old fluid, inspect for metal particles indicating wear, and refill with proper lubricant specifications. Some differentials use conventional gear oil, while others require synthetic fluids or limited-slip additives. Front-wheel drive vehicles integrate differential into the transmission using the same fluid. We identify your vehicle’s differential configuration and recommend appropriate service intervals based on manufacturer specifications and driving conditions like towing that accelerate fluid deterioration.

Transmission Diagnosis

Accurate Problem Identification

Effective transmission repair starts with accurate diagnosis determining whether problems stem from electronic controls, hydraulic systems, or mechanical failures. We connect professional scan tools reading transmission trouble codes, monitoring live sensor data, and commanding solenoid tests. Hydraulic pressure testing measures actual pressures comparing them to specifications, identifying pump problems or internal leaks.

Test drives under various conditions replicate your concerns while monitoring transmission behavior. We inspect fluid condition, check for leaks, and evaluate engine performance affecting transmission operation. This systematic approach prevents unnecessary repairs by identifying actual problems. Diagnosis sometimes reveals that apparent transmission issues actually result from engine misfires, low fluid levels, or simple sensor failures easily corrected.
