How much does it cost to replace a torque converter?
Replacing a torque converter typically costs about $1,000 to $2,000 in total, though a straightforward job on a common car can be closer to $600–$1,400, while complex or luxury-vehicle replacements can exceed $3,000. The final price depends on the car, the shop, and whether the transmission must be removed to access the converter.
What a torque converter is and why it fails
The torque converter is a fluid-coupled device between the engine and the transmission that multiplies torque and smooths power delivery. Common failure symptoms include slipping, shuddering at idle, reduced acceleration, overheating, or transmission fluid contamination. Replacing the converter is sometimes pursued after a rebuild or when the transmission is opened for other repairs, since access and labor are major cost drivers.
Cost components and typical ranges
Prices vary by part type, labor rates, vehicle make/model, and whether any additional transmission work is required. The following breakdown gives a sense of what to expect.
- Parts cost: Torque converters can be aftermarket or OEM. Aftermarket units typically run about $150–$400; OEM or dealer units commonly cost $400–$900. Rebuilt or remanufactured converters may be around $300–$700.
- Labor costs: Replacing a torque converter generally requires removing the transmission, which can take 4–12 hours depending on the vehicle. Labor rates commonly range from $80–$150 per hour, translating to roughly $320–$1,800 in labor.
- Extras and contingencies: Transmission fluid (ATF) replacement, filters, pan gasket, seals, and the torque converter clutch solenoid are common add-ons. Diagnostic fees, core charges for the replacement unit, disposal fees, and potential additional repairs if other transmission issues are found can raise the total.
In practical terms, most people should expect a total bill around $1,000–$2,000 for a typical job. Lower-end scenarios with aftermarket parts and quick turnaround may land near $600–$1,400, while high-end or particularly complex cases can push the total beyond $3,000.
How to get an accurate estimate
To avoid surprises, obtain written, itemized quotes that break out parts, labor, fluids, and any fees. Compare multiple shops and verify what the price covers, including whether transmission removal is included. Here are steps to take when shopping quotes.
- Ask for a full breakdown of parts, labor, fluids, disposal, and any core charges or diagnostic fees.
- Confirm whether the estimate includes removal/reinstallation of the transmission and any ancillary work (e.g., gasket replacements, sealants).
- Check warranty terms on both parts and labor, and understand what is covered and for how long.
Having a clear, written comparison helps you understand what you’re paying for and protects you from hidden charges.
Additional considerations
Some shops may offer a warranty on the converted unit or the labor, typically ranging from 12 months to 24 months or 12,000–24,000 miles. If you’re planning to sell or keep the vehicle for a long time, a reputable remanufactured converter with a solid warranty can provide long-term value.
Summary
Torque converter replacement is a mid-to-high-cost automotive repair driven largely by parts choice and labor complexity. Expect roughly $1,000–$2,000 for a typical job, with variations by vehicle type and shop. Shop around for detailed, itemized quotes, and weigh the balance between price, reliability, and warranty when making a decision.
How long does it take a mechanic to replace a torque converter?
5 to 10 hours
Replacing a torque converter can take anywhere from 5 to 10 hours, depending on the vehicle and the mechanic's experience. Since the transmission must be removed, it's a time-consuming job.
What are the symptoms of a failing torque converter?
Symptoms of a failing torque converter include shuddering or vibrating while driving, poor acceleration or sluggishness, and unusual noises like whining or rattling. Other signs are transmission overheating, the check engine light coming on, and strange shifting or jerking motions. You may also notice high engine RPMs without an increase in speed or delayed engagement when putting the car in gear.
Performance and driving symptoms
- Shuddering or vibration: The vehicle shakes as if driving over rough pavement, often at consistent speeds.
- Poor or delayed acceleration: The car feels sluggish or has a noticeable pause before it picks up speed.
- High engine RPMs without speed: The engine revs up, but the car doesn't accelerate as it should.
- Slipping gears: The car feels like it's losing power or disengaging from gear unexpectedly.
- Hesitation or jerking: The vehicle jerks or hesitates when shifting or accelerating.
Auditory and other symptoms
- Unusual noises: Listen for whining, rattling, or grinding sounds coming from the engine area.
- Transmission overheating: A failing torque converter can cause the transmission fluid to overheat.
- Check engine light: The "check engine" light may turn on, sometimes with specific codes like P0741 or P2757, which can indicate a problem with the torque converter clutch circuit.
- Fluid leaks: A leak of reddish or brownish transmission fluid can be a sign of a damaged seal.
Is it expensive to repair a torque converter?
If you have the skills and tools to replace the torque converter yourself, you might spend between $150 and $500. This estimate includes the cost of the part and any additional supplies you might need. On the other hand, if you prefer to have a professional handle the replacement, expect to pay between $600 and $1000.
Is it worth replacing a torque converter?
Yes, replacing a torque converter is often worth it to avoid further, more expensive transmission damage, especially if the car is still valuable and the repair is significantly cheaper than a new vehicle. The decision depends on the overall cost of the repair versus the value of the car, the extent of the damage to the transmission itself, and the price of a replacement vehicle. Promptly replacing it is crucial because a failing torque converter can circulate damaging debris through the transmission, leading to more severe issues.

When it's worth it
- To save a valuable car: If the car is otherwise in good condition and the repair cost is less than buying a replacement, replacing the torque converter is a wise investment.
- To prevent further damage: A failing torque converter can contaminate the transmission fluid with debris, which can cause irreversible damage to other components. Replacing the torque converter and flushing the system can prevent this.
- When the transmission is otherwise sound: If the transmission only has a minor to moderate issue that a torque converter replacement and a flush can fix, it's often more cost-effective than a full transmission rebuild or replacement.

When it may not be worth it
- For high-mileage or problematic vehicles: If the car has already required frequent repairs or has very high mileage, the cost of a torque converter replacement might not be a good long-term investment.
- When the transmission damage is severe: If the transmission has suffered extensive damage due to the failing converter, a full transmission replacement or rebuild might be necessary, which can be a significant expense. In this case, it might be more sensible to sell the car.
Important considerations
- Get a professional diagnosis: Have a qualified mechanic or transmission shop diagnose the problem to confirm it is the torque converter and not another issue.
- Don't skip the flush: If you replace the torque converter, it's essential to also have the transmission cooler and lines flushed to remove any debris from the old converter.
- Compare repair cost to car value: Before committing to the repair, get a quote and compare it to the current market value of the car to see if it's financially sound.
