Transmission Replacement Cost Calculator

The condition of the transmission case determines the answer. If only the clutch packs, solenoids, or seals have failed, a rebuild saves $600 to $1,500. The case must be structurally sound.

If the case is cracked, bearings are spun, or there is severe internal damage, go with a reman. It comes with a full warranty and predictable price.

Ask the shop to explain what they found during teardown before committing. A reputable shop will show you the damaged parts.

CVT transmissions use a steel push-belt and variable-diameter pulleys instead of traditional gears. The belt kit alone costs $400 to $900, and the fluid is three to four times more expensive than standard ATF.

Jatco and Aisin manufacture most CVT internals, and their parts are OEM with limited aftermarket alternatives.

Fewer shops are certified to rebuild CVTs, which reduces competition and keeps prices elevated. Get at least two quotes from shops that specialize in CVT work rather than general transmission shops.

Check before paying anything. Call the selling dealer with your VIN and ask whether the transmission is still under powertrain warranty. Most manufacturers provide a 5-year/60,000-mile powertrain warranty on new vehicles sold in the U.S.

Certified pre-owned vehicles often extend coverage to 7 years or 100,000 miles.

Some makers also issue Technical Service Bulletins that extend CVT coverage beyond the standard warranty period. A quick VIN check can turn a $3,000 repair bill into a $0 covered repair.

Do not drive on a slipping transmission. Slipping creates friction heat that destroys clutch packs rapidly. Every mile driven while slipping compounds the internal damage and raises the final repair bill.

What might have been a $1,400 rebuild can become a $3,500 replacement if the heat warps the case or damages the torque converter.

If your transmission is slipping, have the vehicle towed to a shop rather than driving it there.

CVT whining or shudder between 25 and 45 mph usually points to a worn belt or pulley kit: $1,400 to $4,000 for the rebuild.

Automatic slipping or delayed engagement often starts as a solenoid or fluid issue. A fluid flush ($150 to $350) or solenoid replacement ($150 to $400) is the first step. If shifting does not improve, expect a rebuild at $1,000 to $4,000.

Fault codes P0750 through P0770 typically indicate a failed solenoid pack: $200 to $600 for the part plus labor.

Manual grinding on upshift means worn synchronizer rings: $500 to $1,500 depending on how many rings need replacement.

No reverse gear on an automatic usually means a failed sun shell or broken band: $400 to $1,800. Have the shop diagnose before approving a full rebuild, because the fix may be narrower than the quote suggests.

A flush uses a machine to exchange all transmission fluid, including the fluid trapped in the torque converter and cooler lines. Total volume is often 12 to 16 quarts.

A drain-and-fill only removes the fluid sitting in the pan, usually 4 to 6 quarts, and relies on gradual dilution over multiple services.

Flush costs more ($150 to $350) but exchanges all the fluid at once. A drain-and-fill ($100 to $200) is considered safer on high-mileage transmissions because a full flush can disturb built-up sediment and cause shifting problems in older units.

Most rebuilds require 8 to 15 labor hours spread over 3 to 5 business days. The shop removes the transmission and tears it down. It orders missing parts, reassembles, reinstalls, and test-drives. Parts access can add time, especially for CVT or European units.

A reman is faster. Expect 4 to 8 labor hours to swap it in. Most shops finish in 1 to 2 days if the unit is in stock.

The torque converter is a fluid coupling that transfers engine power to the transmission. It is bathed in the same transmission fluid, so when the fluid becomes degraded or the transmission slips, the converter sustains damage too.

During a rebuild, the shop should always inspect the torque converter. If the lock-up clutch is worn or the converter is degraded, replacement adds $200 to $800 to the total. Some shops include this in the rebuild quote; others add it after teardown. Ask upfront.

The Transmission Control Module is the onboard computer that controls shift points, line pressure, and torque converter lock-up. After a rebuild, the TCM needs to be reflashed to reset its adaptive learning and match the new internal parts.

This step costs $150 to $400 and requires dealer-level diagnostic software on many vehicles. Some local shops skip it, which leads to rough shifting or delayed engagement after the rebuild. Ask whether TCM reflashing is included in your quote before signing.

Independent transmission specialists often deliver better value than dealers or chains. The key is verifying their specialization. Ask how many rebuilds the shop completes per month. Confirm experience with your specific transmission type and a written warranty with defined terms.

AAMCO and similar franchises vary widely because each location is owner-operated. Warranty terms differ by franchise, so get everything in writing regardless of the brand name on the building.

Regular fluid service every 30,000 to 60,000 miles is the highest-impact preventive measure. For CVTs, follow the OEM interval exactly. Do not rely on "lifetime fluid" marketing: transmission fluid degrades with heat and use, and neglected fluid is behind most CVT failures under 150,000 miles.

Beyond fluid service: never exceed your vehicle's tow rating, address any shifting symptom immediately, and avoid aggressive driving habits that generate excess heat. Deferred diagnosis is the most expensive mistake in transmission repair.

A 2018 Honda Accord has abundant core availability for reman units. A 2005 BMW 5-series with a rare 6HP26 has shrinking core supply, which means the shop may need to source OEM new parts instead of reman.

OEM new parts on a low-volume older vehicle can push a rebuild quote past what a reman replacement would run on a common model. Ask the shop whether they can source reman parts for your specific unit before approving a rebuild on any vehicle older than 15 years.
