We Handle Engine, Transmission, and Drivetrain Repairs  

Engine repair is one of the most involved services a shop can offer, and our team approaches it with the thoroughness it demands. From oil leak repairs and head gasket replacement to timing chain service and engine mount replacement, we work through the full scope of engine block and cylinder head concerns using quality OEM or equivalent parts. If your check engine light is on, our diagnostic process starts with an OBD-II scan to pull diagnostic trouble codes from the engine control module, followed by a deeper evaluation of sensors, the catalytic converter, fuel system components, and emissions systems to pinpoint the actual cause rather than guessing. We handle transmission repair with equal care, whether your vehicle uses a conventional automatic, a CVT transmission, or a manual setup. CVT transmission repair requires specialized knowledge of the pulley system, steel belt or chain, valve body, and control solenoids, and our technicians are equipped to handle it correctly. We also perform transmission flushes using the proper fluid type for your vehicle, whether that is Dexron, Mercon, or CVT-specific fluid, along with filter replacement and pan service to keep your transmission running smoothly. For vehicles under extended warranty, we can assist with documentation and diagnostics to support your claim.  

Other Auto Repair Services Available   

Beyond engine and transmission work, West Automotive Group covers the full range of services your vehicle depends on to stay safe and comfortable. Brake repair is one of our most requested services. We inspect and replace brake pads, rotors, calipers, brake lines, and brake fluid as needed, along with ABS diagnostics and master cylinder evaluation to ensure your stopping power is fully restored. Suspension repair addresses worn shocks, struts, control arms, ball joints, tie rods, sway bar links, and bushings. We follow up with a wheel alignment using precision alignment equipment to restore proper toe, camber, and caster angles according to manufacturer specifications. If your car’s air conditioning is blowing warm or not performing as it should, our A/C repair service covers the compressor, condenser, evaporator, expansion valve, and refrigerant recharge using R-134a or R-1234yf, depending on your vehicle’s requirements. Automotive electrical repair is another area where our diagnostic capabilities shine, helping us trace faults in wiring, sensors, and control modules that other shops might miss. For drivers with hybrid vehicles, our hybrid repair services include battery pack testing, high-voltage system inspection, regenerative braking system evaluation, and software updates to keep your hybrid running at peak efficiency.

Frequently Asked Questions

A steady check engine light may indicate a minor issue like a loose gas cap or a faulty oxygen sensor, while a flashing light often signals a more urgent problem such as engine misfires. Our diagnostic process uses an OBD-II scanner to read trouble codes and evaluate the engine control module, fuel system, and emissions components, giving you a clear answer quickly.
Most manufacturers recommend a transmission flush every 30,000 to 60,000 miles, though this varies by vehicle and driving conditions. CVT transmissions often have their own specific service intervals. Our technicians will check your owner’s manual recommendations and inspect your current fluid condition to determine what your vehicle actually needs.
Common signs include a rough or bouncy ride, pulling to one side, uneven tire wear, or clunking noises over bumps. Worn shocks, struts, ball joints, or tie rods can cause these symptoms. A suspension inspection and wheel alignment check can identify the issue and help restore your vehicle’s handling and stability.
Hybrid vehicles require specialized knowledge, particularly around the high-voltage battery pack, power inverter, and regenerative braking system. Our technicians are trained in hybrid repair and follow proper safety protocols when working with high-voltage components. We also offer routine maintenance like oil changes and brake service for hybrid models.
A standard brake pad and rotor replacement usually takes one to two hours, depending on the vehicle and the condition of components like calipers, brake lines, and the ABS. If we need to order additional parts or do more extensive repairs, our team will clearly communicate the timeline before any work begins. Costs vary based on make and model.
