Transmission repair and replacement cost runs from about $275 for a fluid drain and fill to roughly $6,190 for a new automatic installed at a $132 an hour independent shop, and a CVT pushes the top end past $7,600. Between those sit the jobs owners actually get quoted: a shift solenoid pack or valve body near $1,090, a rebuild of the original unit near $4,040, and a used or remanufactured transmission dropped in for $2,465 or $4,940. The biggest variable is not the shop. It is the type of transmission the car has, and whether the automaker is still paying for its mistakes.
Choose the transmission type, then the symptom or the fix a shop already named. A symptom adds a diagnostic fee and spans cheap to expensive causes; a fix shows the unit price, the book hours to pull and refit it, your state’s labor rate, and used, rebuilt, remanufactured and new prices side by side. Add the car’s private party value to see how much it costs as a share of the car.
Pick the transmission type and either the symptom or the fix you were quoted. The estimate splits the unit or parts, removal and install hours at your state's shop rate and any diagnostic fee, and prices used, rebuilt, remanufactured and new side by side.
Your Estimate
Estimates only, not a quote. Based on 2026 US pricing: RepairPal labor times and parts for fluid, clutch and replacement work, AutoZone removal and install hours, published installed ranges for used, rebuilt and remanufactured units, and state labor rates. Your price depends on the exact transmission code, parts availability and the shop. Sales tax is not included.
Diagnose first: signs your transmission is going and the cheap causes
A stored check engine code narrows a transmission issue faster than a test drive, and each sign below runs from cheapest likely cause to dearest.
- Slipping. Revs flare but the car doesn’t pick up speed. Low or burnt fluid, then a solenoid, then worn internal clutches (a rebuild or a different unit). On a manual transmission it’s almost always the clutch disc.
- Hard or late shifts. A pressure control solenoid, a sticking valve body or software. A rebuilder quoted by ConsumerAffairs says some units only need a software update, so ask about a reflash first.
- Whine, grind or clunk. Bearing or gear wear, or a tired belt in a CVT. Honda’s HR-V procedure has the technician check the drain plug magnet for metal; ask for the same look.
- Delayed engagement. A pause before Drive or Reverse catches points to low fluid or a worn pump.
- A leak. The fluid is usually red. A transmission leak at the pan gasket is cheap to fix and expensive to ignore, since a unit run low cooks itself. The car leak repair cost calculator prices gasket and seal jobs.
Transmission repair and replacement cost by fix
Typical transmission repair cost for each fix on a midsize sedan with a conventional automatic transmission, at an independent auto repair shop charging the $132 national average:
| Fix | Labor | Low to high | Typical |
|---|---|---|---|
| Fluid drain and fill | 1.29 h | $275 | $275 |
| Machine flush (exchange) | flat price | $165 to $290 | $230 |
| Shift solenoid pack or valve body | 2 to 5 h | $480 to $1,695 | $1,090 |
| Clutch, manual gearbox | 6.73 h | $1,730 to $1,765 | $1,750 |
| Used (salvage) unit installed | 6 to 10 h | $1,825 to $3,105 | $2,465 |
| Rebuild of your own unit | 6 to 10 h plus bench work | $2,825 to $5,255 | $4,040 |
| Remanufactured unit installed | 6 to 10 h | $3,825 to $6,055 | $4,940 |
| New OEM unit installed | 6 to 10 h | $5,525 to $6,855 | $6,190 |
RepairPal’s September 2026 average cost of transmission replacement across all models, $6,238 to $6,764 with parts around $5,110, lands on the new row. Its labor line implies 9.2 hours, inside AutoZone’s six to 10 hour range for automatics. Repair costs could swing either way, since luxury makes run about 60 percent higher on parts, and labor rates by state run from $103 to $159 an hour.
Check that a quote includes removal labor. One dealer page headlines a rebuilt unit at $1,100 to $2,800 and a used one at $800 to $1,500 as the transmission replacement cost, leaving out the six to 10 hours a technician spends getting the old unit out, about $790 to $1,320 at the national rate.
Used, rebuilt, remanufactured or new: what each warranty covers
- Used. A car transmission pulled from a wreck, mileage known, history not. LKQ listings ran $991 to $1,762 with a 6 month, parts-only warranty and no labor.
- Rebuilt transmission. Your own unit torn down at a local shop, with worn friction plates, seals and bands replaced. KBB calls it the cheaper of the two overhaul routes, though installed it costs more than a used swap because bench hours are billed on top.
- Remanufactured transmission. Restored to factory spec in a plant, with known weak points updated and the unit tested before it ships. JASPER backs its units with a 3 year, 100,000 mile parts and labor warranty.
- New. Car Talk would not expect a new unit outside a dealer warranty replacement. Outside warranty, it is one of the most expensive repairs a car can need.
The warranty gap is part of the price: a used unit that fails in month seven means paying the six to 10 hours of labor twice, while a JASPER unit failing inside three years is covered.
CVT, DCT and manual: how the type of transmission moves the bill
A CVT (continuously variable transmission) is an automatic that runs a steel belt or chain between two pulleys that change diameter instead of shifting through fixed gears. A worn belt or scored pulley usually means the whole unit will need to be replaced, since few independent shops rebuild these units. Installed prices by type at $132 an hour:
| Type | Remove and refit | Used | Rebuild | Reman | New |
|---|---|---|---|---|---|
| Automatic (geared) | 6 to 10 h | $2,465 | $4,040 | $4,940 | $6,190 |
| CVT | 5.4 to 10 h | $2,840 | $4,885 | $6,055 | $7,680 |
| Manual | 4 to 6 h | $1,585 | $2,610 | $3,195 | $4,010 |
| Dual clutch (DCT) | 8 to 10 h | $3,285 | $5,650 | $7,000 | $8,875 |
The 5.4 hour low edge is Honda’s warranty time for a 2WD HR-V swap; retail book time runs longer. The dual clutch hours come from a single warranty seller, so confirm them for your make and model. On a CVT, choosing reman over dealer-new saves about $1,625.
Warranty extensions that can zero out transmission repair and replacement cost
For a CVT transmission problem, call a dealer with your VIN before any transmission shop. Status as of October 2026:
- Honda HR-V, 2016 to 2020. Honda Service Bulletin 21-047 covers drive belt deterioration for 7 years from the original purchase date or 150,000 miles, and the listed fix is a replacement unit. A 2020 HR-V bought new after October 2019 is still inside its 7 years.
- Nissan Altima 2017 to 2018, Sentra, Versa and Versa Note 2018 to 2019. The Martinez settlement stretched coverage to 84 months or 84,000 miles from the in-service date, fully reimbursed at Nissan dealers and up to $4,750 elsewhere. Most windows close during 2026; a late-sold 2019 Sentra or Versa under 84,000 miles may still qualify.
- Nissan Murano 2015 to 2018 and Maxima 2016 to 2018. The Beaver settlement (final approval July 21, 2025) gave the same 84 months or 84,000 miles, with up to $5,000 back for work at non-Nissan shops. That window has closed for nearly every car.
- Subaru Legacy and Outback 2010 to 2015, Impreza 2012 to 2015, Crosstrek 2013 to 2015, Forester 2014 to 2015, WRX 2015. Subaru bulletin 16-107-17R raised coverage to 10 years or 100,000 miles. Ten years from a 2015 sale ended in 2025, so treat it as expired.
Expired programs still flag designs with a transmission failure history, worth knowing before buying a salvage unit of the same design. Run the VIN through NHTSA’s recall lookup as well.
A slipping CVT on a $7,000 car: four quotes compared
A midsize sedan’s CVT slips under load. The independent shop, at the US average rate, says it will need a transmission replacement and quotes a remanufactured unit. The car would sell for $7,000 running:
- Unit: the $3,850 midpoint of the remanufactured band, times 1.30 for a CVT, is $5,005.
- Removal and refit: 7.7 hours at $132 is $1,016.
- Shop supplies, capped: $35.
- Typical total: $6,055, with a range of $4,650 to $7,465 before tax.
That is 87 percent of the car’s value. A used unit is $2,840 (41 percent), a rebuild $4,885 and a brand-new transmission from the dealer $7,680. Only the used option stays under half, with the shortest warranty of the four. On a covered Nissan or HR-V, the dealer bill could be zero.
Car Talk warns that a transmission can cost more to fix or replace than an older used car is worth. Past half the private party value, run the repair or replace calculator, which weighs the repair bill against a year of payments on a replacement, or read is my car worth fixing for options such as selling as-is. A fresh gearbox behind a motor that burns oil is money misspent, so price that side on the engine repair and replacement calculator.
Drain and fill or flush: the fluid change question
A drain and fill pulls the pan plug, lets the old transmission fluid run out and refills to the mark. RepairPal prices it on a Camry at 1.29 hours plus about $97 of parts, which is $275 at $132 an hour, the same figure the maintenance cost calculator uses. Dropping the pan to change the filter averages $621 to $785 across all models.
A flush uses a machine to exchange the old supply through the cooler lines. Kelley Blue Book puts it at $165 to $290, though RepairPal says it usually costs more than a drain and fill, and Car Talk argues against paying for one. If the owner’s manual calls for a drain and fill, a flush adds nothing.
KBB lists a change at 100,000 miles, RepairPal every 30,000 to 40,000, and Consumer Reports 30,000 to over 100,000, with some brands sold as lifetime; towing shortens all of them. A CVT needs exactly the fluid the automaker specifies, because the belt depends on its friction properties.
What to ask a transmission specialist before you approve the quote
- Which codes are stored, and is the fault electrical, hydraulic or internal?
- Is the quote for a used, rebuilt, remanufactured or new unit?
- How long is the warranty, and does it cover labor as well as parts?
Start with the VIN: ask a dealer whether any warranty extension or recall covers the vehicle’s transmission. Then put the quote into the calculator above and compare transmission repair and replacement cost for used, rebuilt, remanufactured and new on your car. If your route tops half the car’s value, run the repair or replace numbers before you hand over the keys.
Transmission repair vs replacement: owner questions
Is it cheaper to fix a transmission or replace it?
Usually, yes, when the fault is outside the hard parts. A solenoid pack or valve body runs about $1,090 typical, against $2,465 for a used unit installed and $4,940 for a remanufactured one. Once the internal clutches or gears are worn, a rebuild ($4,040) or a replacement unit is the real choice.
How much does a mechanic charge to replace a transmission?
Labor costs alone cover six to 10 hours on an automatic, about $790 to $1,320 at $132 an hour. With the unit, a full replacement averages $2,465 used, $4,940 remanufactured and $6,190 new, before tax, on a midsize sedan. A CVT runs about 15 to 25 percent higher.
Is 100,000 miles too late to change transmission fluid?
Not if the manual says 100,000 or the fluid still looks red and clean, the KBB schedule for many cars. If it is dark and smells burnt, a change will not reverse wear, and some shops advise against a flush on that unit; ask for a drain and fill instead.
How long do transmissions usually last?
Car Talk says they are built to last the life of the vehicle, about 250,000 miles, and most do. Failures cluster early and again as the odometer nears 100,000 miles.
