Transmission problems are expensive to guess at. A slipping shift can be low fluid, a failing solenoid, a software issue, or internal wear, and each one has a very different repair. Our transmission specialist on staff tests before recommending anything, so you are not sold a rebuild when a smaller repair fixes it.

Transmission warning signs
- Slipping: engine revs rise but the car does not speed up
- Low or burnt fluid, worn clutch packs, or a pressure problem inside the transmission.
- Delayed engagement when shifting into Drive or Reverse
- Low fluid, a worn internal seal, or a valve body issue.
- Harsh, late, or erratic shifts
- A shift solenoid, a sensor feeding bad data to the computer, or fluid that has broken down.
- Red fluid under the car
- A leaking pan gasket, cooler line, or seal. Low fluid is one of the most common causes of transmission damage.
- Burning smell after driving
- Fluid overheating, often from low level or heavy towing.
- Check engine light with shifting complaints
- The computer has stored a transmission code. We read it and test the circuit before replacing parts.
- Grinding or a clutch that slips on a manual
- Worn clutch, synchronizers, or a hydraulic problem in the clutch system.
How transmission repair works here
We separate what the transmission is doing from what is causing it. That keeps the estimate tied to the actual fault.
Inspect
We check fluid level and condition, scan for codes, look for leaks, and road test to reproduce the shift problem.
Explain and estimate
Our transmission specialist explains the likely cause and the repair options, from a fluid service or solenoid to a rebuild or replacement. You get a written estimate.
You approve
You choose the repair. If an internal inspection is needed before a firm number, we tell you that up front and get your OK for that step.
Repair
We repair, rebuild, or replace the transmission, then refill and set fluid to the correct level for your make.
Road test
We drive the car through every gear and a range of speeds to confirm the shifts are right.
California's Bureau of Automotive Repair requires a written estimate and your authorization before work begins, and if we find something new partway through, we stop and ask before going further.

Frequently asked questions
Do I need a whole new transmission?
Often not. Many shifting problems come from fluid, a solenoid, a sensor, or a leak. Our transmission specialist tests first, and the written estimate shows each option.
Should I change my transmission fluid?
Follow the interval for your make and model. Many owners never change it. If the fluid is dark or smells burnt, we will tell you what that means for your transmission before recommending a service.
Can I keep driving with a slipping transmission?
We do not recommend it. Slipping creates heat, and heat wears the transmission further. If the car slips, call us before driving it far.
Do you work on manual transmissions?
Yes, including clutch repair.
Which makes do you see most?
Toyota and Honda most often, plus Ford, Jeep, Mercedes-Benz, Mazda, Subaru, BMW, Audi, and Lexus, and most other makes on the road.
