Plan $80 to $400 for a U.S. Transmission Flush and Get MechanicRank Quotes

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. Sample estimates and local shop quotes below will help you budget with confidence.

The short version.

• Basic drain and fill costs between $80 and $250, but a full flush or CVT service can range from $150 to over $400 depending on vehicle size and type.
• Only about 40% to 50% of transmission fluid is replaced during a drain and fill, while a machine flush can remove nearly all old fluid for better system cleaning.
• Synthetic fluids and larger vehicles increase costs, and sealed transmissions or those needing special tools tend to push prices higher.
• Unnecessary flushes, especially on high-mileage or sealed units, can dislodge sludge and cause more harm than good unless recommended by manufacturer intervals.
• Vehicle owners should request detailed quotes, compare local shops, and use verified directories to ensure transparent pricing and proper service.

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.

Here's what typically shows up on your invoice. A component breakdown from Cost Insider shows why totals vary so much between a basic Honda Civic service and something like a Ford F150 4x4 with a larger fluid capacity. 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.

• 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, $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 three services sound similar, but they are not the same job, and the price tag reflects that. Here's the breakdown.

• Drain and fill. A mechanic drains the fluid sitting in the pan, then refills it. This only replaces 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. This costs more because of the equipment and time involved, but it gets old fluid out of places a drain and fill never touches.
• 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 as conventional per quart, and larger vehicles need more of it. Filter and gasket replacement adds parts cost plus extra labor time to drop the pan.

Other factors that show up on your bill. Sealed transmissions and full synthetic fluid requirements are the two things that most often turn a $150 job into a $300 job.

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

• 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.

Watch for these signs that your transmission wants attention now, not later. Check your owner's manual first. It lists the exact interval for your specific model, and pulling a quote based on your actual mileage and symptoms beats guessing.

• 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 gets added in. What DIY doesn't cover is a full fluid exchange, which needs machine equipment most home garages don't have, or catching internal transmission wear a trained tech would spot.

When you get a professional quote, make sure it spells out. Ask the shop directly what fluid they're using and request the old fluid sample if something seems off. A shop that hesitates to answer those questions is one to think twice about.

Pro Tip. Request 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.

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

Finding Shops and Getting Local Quotes

Mechanicrank lists mechanics and shops across hundreds of US cities, along with repair cost guides that help you see what a fair price looks like in your area before you commit to a service.

To get a vehicle specific quote. Reading through the transmission and drivetrain study guide beforehand also helps you understand what a technician means when they explain what's wrong.

• Search your city or zip code to see providers near you
• Compare shop ratings and reviews before requesting 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 a few hundred dollars for a basic drain and fill on most cars, and somewhat 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 your owner's manual mileage first. If a shop finds internal damage during service, that's your cue to get a transmission specialist involved rather than pushing forward with routine fluid work.

Compare Shops Before You Book Anything

There are free directories available that let you shop around instead of calling multiple repair shops yourself. Listed mechanics can be independently verified, with rankings based on real service history rather than paid advertising.

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

How Much Should I Pay for a Transmission Flush?

Expect to pay $150 to $250 for a basic drain and fill or $250 to $400 for a full machine flush on most cars. National averages sit around $147 for a drain and fill and $232 for a full flush, with CVT service often running higher.

Are Transmission Flushes Worth It?

A flush is worth it when your fluid is old, dark, or burnt smelling, or when your manufacturer's schedule calls for it. On a high mileage transmission with heavily degraded fluid, a power flush can sometimes dislodge sludge that was better left in place, so Consumer Reports recommends checking your owner's manual first rather than flushing on a whim.

Is 100,000 Miles Too Late to Change Transmission Fluid?

It's not too late, but it does call for caution. If your fluid has never been changed and the transmission shows signs like slipping or rough shifting, a gentler drain and fill is often the safer starting point rather than jumping straight to a full machine flush.

Does Jiffy Lube Do a Transmission Flush?

Many quick lube chains and national service centers offer transmission drain and fill or fluid exchange services, though exact offerings and pricing vary by location. Confirm the fluid type and what's included in the price before you agree to the work, and consider comparing quotes through a directory like Mechanicrank first.
