* 4L60E: A 4-speed automatic overdrive transmission. This was the most prevalent option.
* 700R4: A 4-speed automatic overdrive transmission, though less common than the 4L60E in '94.
To know for sure which transmission is in a specific 1994 Suburban, you'd need to check the vehicle's documentation (owner's manual, build sheet if available) or look at the transmission itself for identifying markings.
