* TH700-R4: This was a three-speed automatic overdrive transmission and likely the most prevalent option.
* Turbo-Hydramatic 350: A three-speed automatic, but *without* overdrive. Less common than the TH700-R4.
* Manual transmissions: While less frequent, some Caprices were available with a manual transmission, likely a four-speed. The specific model number would depend on the engine and overall trim level.
To know for sure which transmission is in a *specific* 1985 Caprice, you'd need to check the vehicle's documentation (owner's manual, build sheet if available) or look for a sticker or tag on the transmission itself. The transmission type is also often stamped on a metal tag on the vehicle's data plate (usually found in the driver's side door jamb).
