Transmission Repair Cost
Average cost: Most transmission repairs cost $200 to $1,500, while a full rebuild runs $2,300 to $6,000 and a new replacement transmission $3,800 to $8,000 installed, according to CoverageX. A fluid leak fix costs $200 to $500, a shift solenoid $75 to $450 (AutoNation Mobile Service) and a valve body $300 to $1,000. A diagnostic usually comes first at $200 to $300.

"Transmission repair" covers everything from a $200 seal to an $8,000 replacement, so the first number that matters is the diagnosis. Many shifting problems turn out to be low fluid, a leak, a failed solenoid or a software issue rather than a dead transmission. CoverageX puts most targeted repairs at $200 to $1,500, a rebuild at $2,300 to $6,000 and a brand-new unit at $3,800 to $8,000, parts and labor included.
Common transmission repairs and their cost
| Repair | Typical cost | Source |
|---|---|---|
| Diagnostic (scan and road test) | $200 – $300 | CoverageX |
| Fluid leak (seals, pan gasket, lines) | $200 – $500 | CoverageX |
| Transmission fluid change | $300 – $510 | AutoNation Mobile Service |
| Fluid flush or cooler service | $300 – $800 | CoverageX |
| Single shift solenoid | $75 – $450 | AutoNation Mobile Service |
| Solenoid pack | $250 – $600 | AutoNation Mobile Service |
| Solenoid or harsh-shifting repair, shop total | $800 – $1,500 | CoverageX |
| Valve body | $300 – $1,000 | AutoNation Mobile Service |
| Torque converter (part) | $200 – $400 | CoverageX |
| Torque converter rebuild, installed | $800 – $1,500 | CoverageX |
AutoNation Mobile Service splits the single-solenoid job into $15 to $100 for the part and $60 to $350 for labor. The labor swing is wide because on some cars the solenoid sits behind the pan and takes an hour, while on others the valve body or the whole transmission has to come out.
Repair, rebuild or replace?
When the damage goes beyond one component, you have three options. CoverageX's installed price ranges:
| Option | Installed cost | What you get |
|---|---|---|
| Used transmission | $1,600 – $4,000 | Salvage unit of unknown history; cheapest, shortest warranty |
| Rebuilt transmission | $2,300 – $6,000 | Your unit (or an exchange unit) torn down, worn parts replaced |
| New or remanufactured unit | $3,800 – $8,000 | Factory-spec unit, longest warranty |
Labor for removing and installing a transmission runs $800 to $2,500 on its own, according to CoverageX, which is why a rebuild of your own transmission and a swap for a used one can end up close in price.
A repair makes sense when a scan and inspection point to one failed part: a leaking seal, a stuck solenoid or a clogged filter. A rebuild is the usual answer when internal clutches, bands or bearings are worn but the case and gears are sound. A replacement is the choice when the case is cracked, metal debris has spread through the unit, or the rebuild quote approaches the price of a remanufactured transmission with a better warranty. For a full replacement price breakdown by labor and parts, see our transmission replacement cost guide.
Cost by transmission type
The type of transmission in your car has a large effect on the bill. CoverageX's installed ranges for a major repair or replacement:
| Transmission type | Typical cost |
|---|---|
| Manual | $2,600 – $5,000 |
| Conventional automatic | $3,500 – $6,500 |
| CVT (continuously variable) | $4,200 – $7,800 |
| Dual-clutch (DCT) | $5,200 – $8,500 |
Manual transmissions are the simplest and cheapest to fix, and many problems on a manual car are really the clutch rather than the gearbox; see our clutch replacement cost guide. CVTs and dual-clutch units are more complex, often need dealer-specific parts and software, and fewer independent shops rebuild them, which pushes prices up.
Warning signs to get checked early
Catching a problem early is the best way to keep the bill at the low end of the table. Get the car looked at if you notice:
- Slipping: engine revs climb but the car does not speed up.
- Delayed or harsh engagement when shifting into drive or reverse.
- Rough, late or erratic shifts, or the car stuck in one gear (limp mode).
- Red or brown fluid under the car, usually toward the front or middle.
- A burning smell, which often means overheated fluid.
- Whining, clunking or humming that changes with gear rather than engine speed.
- A check engine or transmission warning light. A code reader can show whether a transmission code is stored.
Do not keep driving a slipping transmission. Heat and friction inside a slipping unit can turn a solenoid or fluid problem into a full rebuild.
What affects your quote
- Vehicle make and model. Luxury, European and four-wheel-drive vehicles typically cost more for parts and labor.
- Front- or rear-wheel drive. On many front-wheel-drive cars the transmission is packed tightly in the engine bay, adding labor hours.
- Shop type. Dealers usually charge more per hour than independent transmission specialists, but may have factory software needed for programming.
- Programming. Many modern automatics need software relearning or reprogramming after a valve body, solenoid or unit swap.
- Warranty. A longer parts-and-labor warranty is often built into a higher quote.
How to keep repair costs down
- Start with the fluid. Check the level and condition where your car allows it. Low or burnt fluid is a cheap fix compared with internal damage.
- Pay for a proper diagnostic. A $200 to $300 inspection with a scan tool and road test is cheaper than replacing parts on a guess.
- Ask for the failed part or code. A specific diagnosis ("pressure control solenoid", "leaking front pump seal") makes quotes comparable.
- Get at least two quotes, including one from an independent transmission specialist.
- Compare warranties on rebuilt and remanufactured units, not just prices.
- Follow the maintenance schedule. Regular fluid service, covered in our transmission fluid change cost guide, is the cheapest protection a transmission gets.
Is it worth fixing an older car?
Compare the repair quote with the car's value and condition. If a rebuild costs $4,000 on a car worth $5,000 that otherwise runs well, the repair can still be the cheaper path than buying a replacement vehicle. If the engine, suspension and body also need work, the transmission bill may be the signal to sell. A used transmission with a short warranty is the budget option for a car you plan to keep only a year or two.
