MR. STAC stocks used automatic and manual transmissions for GMC vehicles from licensed South Carolina salvage yards — graded A–D and priced to move. We part out GMC Sierra, Acadia, Yukon, Terrain, and Canyon, and source from 50+ SC yards when a part isn't on our shelves. Nothing in stock this minute? Submit a request and we'll track it down, usually within one business day. Call 843-933-4068.
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.
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.
Tell us your VIN or year/make/model. We search our 50+ yard network and call you back — free, no obligation.
