What a transmission replacement involves

Replacing a transmission means removing the old unit and installing a new, remanufactured, rebuilt or used one. It is one of the most expensive repairs on a car, and RepairPal's average shows that the transmission itself makes up most of the cost.

Signs of serious transmission trouble

  • Slipping between gears or the engine revving without the car accelerating.
  • Harsh, delayed or erratic shifting.
  • Refusing to engage drive or reverse.
  • A check engine or transmission warning light.
  • Burning smell or dark, burnt-smelling transmission fluid.
  • Grinding, whining or clunking noises.

Get a diagnosis first

Many transmission symptoms are caused by problems that are much cheaper to fix: low fluid, a faulty sensor, a solenoid, wiring or software. A shop should scan for codes, check the fluid level and condition, and road test the car before recommending a replacement.

Your options

  • Used transmission: the cheapest option, from a salvage vehicle. History and condition are unknown; warranties are usually short.
  • Rebuilt: your transmission or another unit is disassembled, worn parts are replaced and it is reassembled by a shop.
  • Remanufactured: rebuilt in a factory setting to set standards, often with updated parts and a longer warranty.
  • New: the most expensive, usually from the manufacturer.

Repair, replace or sell?

On an older car, a transmission replacement can cost more than the car is worth. Compare the quote with the car's value and the condition of the rest of the car before deciding. On a newer car or one in good condition, a remanufactured transmission can add many years of use.

Keep fluid in good condition

Low or old fluid causes overheating and wear in automatic transmissions. Follow the service schedule in the owner's manual and fix leaks promptly.

Questions to ask the shop

  1. How did you confirm the transmission needs replacement rather than repair?
  2. Is the replacement used, rebuilt, remanufactured or new?
  3. What warranty covers it, for how long, and is it valid at other shops?
  4. Does the quote include fluid, cooler flushing and any software updates?

How the job is done

  1. The shop diagnoses the transmission and confirms replacement is needed.
  2. Fluid is drained and connections, lines, axles or the driveshaft are removed.
  3. The transmission is supported on a jack, unbolted from the engine and lowered out of the car.
  4. The replacement transmission is prepared, and parts such as the torque converter are installed or checked.
  5. The transmission is raised into place, bolted to the engine and reconnected.
  6. The cooler lines are flushed, fluid is filled to the correct level, software is updated or relearned if required, and the car is road tested.

Frequently asked questions

Is it cheaper to rebuild my transmission? Sometimes, depending on what failed. A rebuild can cost less if damage is limited, while severe damage often makes a remanufactured unit the better value.

Does a transmission replacement come with a warranty? Most remanufactured and rebuilt units do. Ask how long it lasts and whether it is honored nationwide.

Can a transmission problem be fixed with a software update? Some shifting issues are caused by software. Manufacturers sometimes release updates that change shift behavior.

Should I buy a used transmission? It can save money on an older car, but its history is unknown. Look for a seller who offers a warranty.

Is your quote fair?

Compare your written quote with the national range above. A quote well above $6,764 is not automatically wrong, because some vehicles need more parts or more hours, but it is worth asking the shop to explain the difference. Ask for the quote to be split into parts and labor, and for the parts to be listed by name and brand. If the labor portion is far above $1,654, ask how many hours the shop is charging and what makes your car take longer. Getting a second written quote for the same parts is the simplest way to check a price.

Repair, rebuild or replace

Not every transmission problem requires a new transmission. A shop should first scan for codes, check the fluid level and condition, and test sensors, solenoids and the control module. Some problems, such as a faulty solenoid or a software issue, can be fixed for a fraction of the cost of replacement. When the internal parts are damaged, the options are a rebuild of your transmission, a remanufactured unit or a used transmission. Each has different warranty terms and risks.

Deciding whether it is worth it

A transmission replacement costs a large share of what many older cars are worth. Compare the quote with the car's value and condition. A vehicle with a solid engine and body may be worth the investment, especially with a remanufactured unit and a strong warranty. A car that also needs other major repairs may not be. Get the warranty terms in writing, including whether labor is covered and whether the warranty is honored at other shops if you move.

After the replacement

Follow any break-in instructions, keep the receipt, and have the fluid level checked at the first oil change. Some transmissions need an adaptation or relearn procedure so the computer learns shift points; ask whether this was done.

Fluid and cooler

After a major failure, metal debris can remain in the transmission cooler and lines. Many warranties require flushing or replacing the cooler when installing a new or remanufactured transmission.

Towing to the shop

Avoid driving a slipping transmission to the shop; towing it prevents further damage.
