What to check on a used GMC Transmission
Match the transmission code, gear count, and drivetrain (FWD, RWD, or AWD) to your vehicle, and verify the mileage. A tested Grade A unit shifts cleanly with no slip. GMC shares most drivetrain and body parts with its Chevrolet counterparts — the Chevy equivalent often fits.
Grades & pricing
Used transmissions run about $300–$1,800 versus $1,500–$4,000+ for a rebuild or reman.
We grade every part A (excellent / low-mileage), B (good), C (fair), or D (core / rebuildable) so you know exactly what you're buying.
