Which gm cars have a 700r4 transmission?

The 700R4 automatic transmission was used in a wide variety of GM vehicles, primarily from the mid-1980s to the early 1990s. It's impossible to give an exhaustive list, as many models and trim levels used it across multiple years. However, it was common in these types of vehicles:

* Chevrolet: Camaros, Caprices, Monte Carlos, Corvettes (some years), Silverados (some years, especially light-duty trucks), and many other models.

* Pontiac: Grand Prixs, Firebirds, and others.

* Buick: Regals, LeSabres, and others.

* Oldsmobile: Cutlasses, Delta 88s, and others.

* GMC: Light-duty trucks (Sierra, etc) and some vans.

To know for sure if a specific GM vehicle had a 700R4, you'd need to check its vehicle identification number (VIN) and the specifications for that particular year and model. A repair manual or online resources specific to the vehicle are helpful for this.
