Get a diagnosis before a rebuild quote. Slipping, harsh shifts or a warning light can come from a sensor, a solenoid or low fluid rather than a failed transmission. Ask whether the diagnostic fee is credited toward the repair and what warranty comes with a rebuild.

Good to know

How much does a transmission rebuild cost?

A rebuild commonly costs about $1,500–4,000 for most cars, and a remanufactured replacement can cost more; smaller repairs such as a solenoid or a leaking seal cost far less.

Should I rebuild or replace my transmission?

A rebuild keeps your unit and replaces the worn parts; a remanufactured transmission is a factory-rebuilt unit, often with a longer nationwide warranty. Ask the shop for both prices and compare the warranties.
