Transmission Flush Cost Runs $80 to $400

A transmission drain and fill typically runs $80 to $250, while a full machine flush costs $150 to $400 depending on your vehicle and where you take it. CVT transmissions often push past $300. The biggest price swings come from your vehicle type and whether the shop does a basic drain or a full fluid exchange. The sample estimates below will help you budget and judge local quotes.

• A basic drain and fill costs between $80 and $250, while a full flush or CVT service can run from $150 to over $400 depending on vehicle size and type.
• A drain and fill replaces only about 40% to 50% of the transmission fluid, while a machine flush can remove nearly all of the old fluid.
• Synthetic fluid and larger vehicles raise the cost, and sealed transmissions or units that need special tools push prices higher still.
• Unnecessary flushes, especially on high mileage or sealed units, can dislodge sludge and do more harm than good, so follow the manufacturer's interval.
• Ask for detailed quotes, compare local shops, and read customer reviews so the pricing is clear and the service is done properly.

How Much Does a Transmission Flush Cost?

A basic drain and fill lands between $80 and $250 in most parts of the country. A full machine flush, which pushes new fluid through the entire system including the torque converter and cooler lines, runs $150 to $400. CVT service tends to cost more because of specialized fluid and a trickier fill process.

National averages from a 2026 cost aggregator put a drain and fill at about $147 and a full flush at $232, with CVT services averaging closer to $298. Your actual bill depends on labor rates in your area, the type of fluid your car needs, and whether a filter or pan gasket gets replaced along the way.

A sedan drain and fill might land around $120 total. A full size truck getting a complete flush with a filter change can climb to $350 or more once you add synthetic fluid and extra labor time. This is what typically shows up on the invoice.

• Shop fee or labor. $40 to $120, depending on how long the job takes and your local labor rate.
• Fluid. $8 to $15 per quart for conventional fluid or $12 to $25 per quart for synthetic, and most transmissions need 4 to 14 quarts.
• Filter and pan gasket. $15 to $60 if your shop does a full service instead of just a drain.
• Disposal fee. $5 to $15 in many states.

Drain and Fill vs Fluid Exchange vs Machine Flush

These services sound similar, but they are not the same job, and the price reflects that.

• Drain and fill. A mechanic drains the fluid sitting in the pan, then refills it. This replaces only about 40% to 50% of the total fluid because the torque converter and cooler lines still hold old fluid. It's the cheapest option and the one most manufacturers actually recommend for routine maintenance.
• Filter and pan service. This adds a new filter and pan gasket to the drain and fill. It costs more in parts and labor but catches debris that a plain drain and fill leaves behind, and it's a smart add on if your transmission has 60,000 miles or more on the original filter.
• Fluid exchange or machine flush. A machine connects to the cooler lines and pushes fluid through the entire system under pressure, replacing nearly all of it. It costs more because of the equipment and time involved, but it gets old fluid out of places a drain and fill never reaches.
• CVT and manual transmission fluid. CVTs need a specific fluid formula that costs more per quart, and the fill process is more finicky. Manual transmissions use gear oil instead of automatic transmission fluid, and service is usually cheaper since there's no torque converter to deal with.

What Actually Drives the Price You're Quoted

Fluid type and quantity matter most. Synthetic fluid can cost twice as much per quart as conventional, and larger vehicles need more of it. Filter and gasket replacement adds parts cost plus extra labor to drop the pan. Sealed transmissions and full synthetic fluid requirements are the two things that most often turn a $150 job into a $300 job.

If a shop tries to sell you a flush at every oil change with no mileage or symptom based reason, ask it to show you the manufacturer's recommendation in writing. Repeated, unnecessary flushing on an older high mileage transmission can stir up sludge that was better left alone, according to Consumer Reports.

Other factors that show up on your bill include these.

• Local labor rates, which swing widely between a small independent shop and a dealership service department.
• Diagnostic time, if the shop needs to figure out why your transmission is acting up before recommending a service.
• Disposal fees and sales tax, which some shops list separately.
• Sealed transmission design, which requires special tools and drives up labor cost on many newer vehicles.

When Do You Actually Need a Transmission Flush?

Most manufacturers recommend transmission service somewhere in the 30,000 to 50,000 mile range, though some sealed units stretch that interval much further. Severe use, like frequent towing, stop and go traffic, or hot climates, shortens that window, according to AAA.

Check your owner's manual first. It lists the exact interval for your model, and a quote based on your actual mileage and symptoms beats guessing. These signs mean your transmission needs attention now, not later.

• Slipping gears, or a delay before the car engages after shifting into drive.
• Rough or jerky shifts between gears.
• Fluid that smells burnt or looks dark brown instead of red.
• Whining or grinding noises that change with vehicle speed.

DIY Drain and Fill or Call a Professional?

A DIY drain and fill can save you real money, mostly on labor. Fluid alone might run $40 to $100 depending on quantity and type, versus $150 or more once a shop's labor is added. What DIY doesn't cover is a full fluid exchange, which needs machine equipment most home garages don't have, or the internal transmission wear a trained tech would spot.

Ask for an itemized quote before any work starts. A one line total hides whether you're paying for a basic drain and fill or a full flush, and that difference alone can be $100 or more. Ask the shop directly what fluid it is using, and request a sample of the old fluid if something seems off. A shop that hesitates to answer those questions is one to think twice about.

A professional quote should spell out the following.

• The exact fluid type and how many quarts your transmission needs.
• Whether a filter and pan gasket are included.
• The labor charge, separate from parts.
• Any warranty on the work.

Finding Shops and Getting Local Quotes

MechanicRank lists mechanics and shops across hundreds of U.S. cities, along with repair cost guides that show what a fair price looks like in your area before you commit to a service. Reading the transmission and drivetrain study guide beforehand also helps you understand what a technician means when they explain what's wrong.

To get a quote for your specific vehicle, follow these steps.

• Search your city or zip code to see providers near you.
• Compare shop ratings and reviews before asking for pricing.
• Ask for a written quote that lists fluid type, quantity, and labor separately.
• Check the transmission replacement cost guide if a shop flags deeper internal wear, so you understand the long term cost picture.

A Straightforward Way to Budget This

Budget $80 to $250 for a basic drain and fill on most cars, and more if you're getting a full flush or your vehicle uses a CVT. Add a small contingency for a filter or gasket the shop finds along the way.

Get at least two quotes from different shops, and check the mileage interval in your owner's manual first. If a shop finds internal damage during service, that's your cue to bring in a transmission specialist rather than pushing forward with routine fluid work.

Compare Shops Before You Book Anything

A free directory lets you shop around without calling one repair shop after another. On MechanicRank, owner-verified listings are claimed by the businesses themselves, and ratings come from public customer reviews, so read those reviews the way you would any other.

You can search by city to pull up mobile mechanics and repair shops near you, compare their ratings side by side, and contact a few for a quote on your specific vehicle before committing to anything. If your transmission needs more than routine service, MechanicRank's directory also lists diesel and heavy duty specialists and body shops for bigger jobs down the road. Search your city and get quotes from a few shops so you know your price before you drop off your car.
