* TH350 (Three-speed automatic): This was a very popular automatic transmission in GM vehicles of that era. It's the most likely candidate.
* TH200-4R (Four-speed automatic): Less common than the TH350, but possible depending on the options package.
* SM465 (Four-speed manual): A robust manual transmission, also a possibility, though less likely than the automatics.
* Saginaw 4-speed manual (muncie): Less likely than the SM465, but another possible manual transmission. Generally these were considered heavier-duty.
To know for certain what transmission is in a *specific* 1982 El Camino, you'd need to check the vehicle's identification number (VIN) or look at the transmission itself (the markings on the transmission case will identify it). The owner's manual (if available) would also list the transmission type.
