Transmission repair is one of the most expensive jobs a car can need, which is why catching problems early matters. Many transmission failures start with something small, like old fluid or a leaking seal. This page explains the common services, typical prices, and how to tell whether you are looking at a minor repair or a rebuild.

Replacing the transmission fluid and often the filter. Cheap compared to repairs, and the best way to extend transmission life.
Leaking seals, faulty sensors and shift solenoids. These often cost far less than a rebuild.
For manual transmissions, or dual-clutch units. Clutches are wear items and eventually need replacing.
For internal damage. A rebuild reuses and repairs your unit, while replacement uses a new, remanufactured or used one.
Typical ranges only. Automatic, CVT and dual-clutch units differ a lot, and so do parts costs.
The engine revs but the car does not accelerate as it should.
A long pause or a jolt when shifting into drive or reverse.
Overheated fluid. Stop driving and have it checked.
Transmission fluid is usually reddish. A leak needs attention.
The car may limit speed and gears to protect itself.

Follow your owner's manual, but many shops recommend every 60,000 to 100,000 km. Some manufacturers call their fluid "lifetime", though many mechanics still suggest servicing it.
Neither is always better. A quality rebuild can be a good value, while a remanufactured unit can come with a stronger warranty. Ask the shop what is covered and for how long.
Yes. A proper diagnosis includes a road test, a scan for codes, and a check of fluid level and condition. Get the findings and quote in writing.
A continuously variable transmission uses a belt and pulleys instead of fixed gears. It needs the specific fluid for that model, so do not let a shop use a generic one.
