Diagnosed before anything is recommended

Transmission service and repair in Sacramento

Slipping, hard or delayed shifts, a shudder at speed, or a transmission warning light — we diagnose first. Often the answer is a fluid service or a solenoid, not a whole transmission. When it is major, we give you real numbers for rebuild vs. replace.

What's included

What we’ll tell you

After the diagnostic you get one of three answers: it’s a service (fluid, filter, adjustment), it’s a repair (solenoid, sensor, seal, valve body), or it’s the unit. For the last one we quote rebuild and remanufactured side by side.

Transmission service and repair questions

Is my transmission shot?

Not necessarily. Many symptoms come from low or burnt fluid, a failing solenoid or a sensor. Diagnosis first, then an honest conversation.

How often should transmission fluid be changed?

Follow the manufacturer interval — commonly 30k–60k miles. "Lifetime" fluid is a lifetime of the warranty, not the car.
