Why get your fluid done at a transmission shop

We have rebuilt thousands of transmissions

We have rebuilt thousands of transmissions: automatic, manual, CVT, and diesel and heavy-duty units, on domestic cars, imports like Toyota, Honda and BMW, trucks and SUVs. We have seen what worn-out fluid leaves behind, and we know what to look for when we drain yours.

We check it before we sell you anything

We look at your fluid and check how the transmission shifts before we recommend a change or a flush. High-mileage car, fluid never changed? Same answer: we check it first and tell you honestly what we find.

Both services, so you get the right one

We do a drain-and-refill fluid change and a full machine flush, so we have no reason to push one over the other. A new filter and pan gasket go in when your transmission needs them, or when you ask.

If we find a problem, you hear about it first

No work beyond the fluid service happens without your agreement. If a repair is needed, you get a detailed estimate with no hidden fees, and repairs are covered by our 3 years or 36,000 miles warranty on parts and labor.

How it works

Fluid change or flush: what each one does

A fluid change drains the old fluid and refills it with fresh. A flush uses a machine to push out nearly all the old fluid and replace it. Fresh fluid is the cheapest thing your transmission will ever ask for, and we would love to keep it that way. If your transmission is already slipping, leaking or shifting hard, start with transmission repair and diagnosis instead.

Step by step, from your call to pickup
  • You call the shop and tell us about your car. We book you in.
  • The check: we look at the fluid and how the transmission shifts.
  • Our advice: a fluid change, a flush, or a closer look, and the price. Nothing starts until you approve it.
  • The service: old fluid out, fresh fluid in, plus a new filter and pan gasket when needed.
  • Pickup: your car back with fresh fluid, and a straight answer on how your transmission looked.

Questions

Transmission fluid questions, answered

Anything not covered here, call the shop on (602) 612-4198.

Do I need a transmission fluid change or a flush?

It depends on the condition of your fluid and your transmission, so we check it first. A fluid change drains and refills part of the fluid. A flush uses a machine to replace nearly all of it. We look at the fluid, check how the car shifts, and tell you which one your vehicle needs before we do anything.

My car has high mileage and the fluid has never been changed. Is it safe?

We check it first. We look at the fluid and how the transmission shifts before we recommend anything, and we tell you honestly what we find.

How much does a transmission fluid change cost?

It depends on your vehicle, how much fluid it takes, and whether it needs a new filter and pan gasket. Call the shop and we will give you a price for your vehicle before any work starts.

Do you replace the transmission filter?

Yes, when your transmission needs one or when you ask for it. A new pan gasket goes on at the same time.

How often should transmission fluid be changed?

Your owner's manual lists the interval for your vehicle. Most manuals give a shorter interval for severe driving, which includes heavy heat, towing and stop-and-go traffic. If you are not sure when it was last done, we can check it for you.

What if you find a problem with my transmission?

We tell you what we found and what it means before any more work is done. Repairs are covered by our 3 years or 36,000 miles warranty on parts and labor.
