What it costs
The path you choose sets the price. A rebuild runs $2,500 to $4,500, a used or salvage transmission installed runs $1,500 to $3,500, a remanufactured unit runs $3,000 to $5,000, and a new OEM transmission can exceed $6,000.
CVTs and dual-clutch transmissions often cost more and sometimes must be replaced rather than rebuilt.
Rebuild vs replace
A rebuild reuses your case and replaces worn internals, clutches, and seals. A replacement swaps in a used, reman, or new unit. Rebuilds can be cost-effective, while reman units offer a good warranty balance.
Rebuild: $2,500 to $4,500
Used/salvage unit installed: $1,500 to $3,500
Remanufactured unit installed: $3,000 to $5,000
New OEM: $4,000 to $6,000+
Signs you need it
Slipping between gears, harsh or delayed shifts, grinding or whining, burnt-smelling or metal-flecked fluid, a check-engine transmission code, or the car refusing to move all point to serious transmission trouble.
Slipping or flaring between gears
Hard, delayed, or missed shifts
Burnt fluid smell or metal in the pan
Whining/grinding or no movement
DIY vs shop
Transmission R&R is heavy, precise work needing a lift, transmission jack, and specialized knowledge. This is not a typical driveway job. A reputable transmission specialist with a solid warranty is the usual choice.
How to save
Rule out cheaper causes first, since low fluid, a bad solenoid, or a worn mount can mimic failure. On an older car, compare the repair to the car's value. A quality used unit with a warranty is often the best value.

❓ FAQ
Is it cheaper to rebuild or replace a transmission?
A rebuild or a used unit is usually cheaper than a new OEM transmission. Reman units cost more but offer a strong warranty.
Can a transmission be fixed without a rebuild?
Sometimes. A slipping issue can trace to low or burnt fluid, a solenoid, or a valve body. Diagnose before assuming a full rebuild.
How long does a transmission last?
Well-maintained automatics often last 150,000 to 200,000 miles. Skipped fluid services and overheating are the main killers.
Is a used transmission risky?
It carries some risk, but a low-mileage used unit with a warranty from a reputable yard is often a smart, affordable choice.
Does a slipping transmission mean replacement?
Not always. Slipping can start from low fluid or a failing solenoid. Have it diagnosed before committing to a rebuild or replacement.
Should I fix the transmission or sell the car?
Compare the repair cost to the car's value and condition. On a high-mileage car worth little, replacement may not make financial sense.
