Smog Mart Inc, Smog and Automobile Repair Center
Diagnosed first · honest answer on service, repair or replace

Transmission service and repair in Sacramento. Diagnosed before anything is recommended.

Slipping, hard or delayed shifts, a shudder at speed, a leak, 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, you get straight numbers before you decide.

What the symptom usually means

Three things we see most

  1. Slipping or delayed shifts

    Often low or burnt fluid, or a solenoid. We check the fluid and read the transmission codes before anyone says the word rebuild.

  2. Leak under the car

    Pan gasket, seals or cooler lines. Usually a repair, not a transmission. Left alone, a leak becomes the expensive problem.

  3. Shudder, hard shifts or a warning light

    Can be fluid, a sensor, a valve body, or the unit itself. The diagnostic tells us which, and you see the findings.

What we service

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, transfer case), or it’s the unit. If the unit needs a full rebuild, we work with a trusted local transmission specialist and coordinate the job for you. We can also install rebuilt or remanufactured units when that makes more sense. We lay the options out side by side so you can decide with real numbers, and the $175 diagnostic is credited toward whichever you choose to have us do.

A transmission warning light often comes with engine codes. If the check engine light is on too, the engine diagnostic covers both.

Common questions

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 about what it actually needs.

How much will it cost?

The diagnostic is $175, credited toward the repair if we do the work. After that you get the findings and, if you want us to do the work, an estimate. Transmission work ranges from a fluid service to a replacement, so we don't guess at a number over the phone.

How often should transmission fluid be changed?

Follow your manufacturer's interval. If the fluid looks dark or smells burnt when we check it, we tell you. Fluid service is quoted by vehicle, since the fluid, capacity and procedure differ.

Do you rebuild transmissions?

If the unit needs a full rebuild, we work with a trusted local transmission specialist and coordinate the job for you at competitive pricing. We can also install rebuilt or remanufactured units when that makes more sense, and we do the removal and installation here.

Do you work on transfer cases?

Yes. We diagnose and repair transfer cases on 4WD and AWD vehicles.

What warranty applies?

Repairs using new parts installed by us carry our 12-month / 12,000-mile parts-and-labor warranty. Rebuilt or remanufactured units carry the manufacturer's or remanufacturer's warranty where applicable. Used units are sold without warranty unless a specific written warranty is stated for that job.

The car won't drive. Can you help with a tow?

Yes. Give us a call. We work with trusted towing partners and can help you arrange service to the shop.
