Chevrolet Repair in Pasadena

Active Fuel Management (AFM)

AFM/DoD lifter failures on 5.3L engines are a documented GM issue. We can diagnose lifter noise and discuss AFM delete options if appropriate.

Transmission Service

8-speed and 10-speed automatic fluid and filter service. GM transmissions are often serviced too infrequently — we follow GM's own recommendations.

4WD & Transfer Case

Silverado and Colorado 4WD systems: front differential, transfer case fluid, actuator diagnosis. Auto 4WD issues are common.

Cooling System

Water pump, thermostat, radiator, coolant flush. Silverado 5.3L and 6.2L cooling systems need regular attention at higher mileage.

Chevrolet Models We Work On

My Silverado 5.3L is ticking. Is that the AFM lifters?

Probably. Gen IV 5.3L engines have a well-documented AFM lifter failure. If you're hearing a tick that started around 80-120k miles, we can diagnose with a GDS2 scan and mechanical inspection.

Do you do AFM delete on GM trucks?

We can discuss it. An AFM delete involves replacing the lifters and disabling the system via a tune. It's a significant repair but eliminates the recurring failure mode.

My Equinox has oil consumption. Is that normal?

Earlier 2.4L Equinox and Malibu engines had a known oil consumption issue. There was a class action settlement. We can check your VIN for any outstanding remedies.

Can you program a new Chevy key fob?

Yes. Standard key fobs, smart keys, and push-to-start proximity fobs. GM programming with factory-spec software.

Do you service Chevy fleet vehicles?

Yes. We're authorized for Element Fleet and Enterprise Fleet Management. Commercial and fleet accounts are welcome.
