The 24 shops on this page work on transmissions in and around Commerce City, CO. What each one says about rebuilds, warranty terms and the brands it handles comes from its own website; ratings and quotes come from public reviews.
If it is slipping badly, overheating or stuck in limp mode, have it towed. Driving a failing transmission turns worn friction material into metal in the fluid, and that debris can make a repairable unit a replacement. Short and slow beats highway speed if you must move it.
On a manual, the engine revs climb without the car speeding up, usually in a high gear on a hill. The bite point creeping toward the top of the pedal travel is the other sign. A crunch going into gear points more at a worn synchro or the clutch not releasing fully.
Weigh the repair against what the car is worth running, and against what else is tired on it. A sound body, good engine and fresh tires argue for fixing it. Rust, a burning engine and worn suspension argue the other way. Ask the shop what it would do with the car.
