Buick Used Transmissions

Shop used Buick transmissions for the LaCrosse, Regal, Encore, Enclave, Envision, Lucerne and Rainier, covering model years 2000 through 2022. We list 224 Buick units across 10 model lines, covering the front-drive sedans and the Enclave and Envision crossovers.

These are GM transaxles, shared with the equivalent Chevrolet and GMC models of the same years — the Enclave and the Chevrolet Traverse are the clearest example — so interchange is well documented. Front-drive and all-wheel-drive versions take different units, so confirm which your vehicle has.
