* 4L60E: This was a very common four-speed automatic transmission.
* 700R4: A four-speed automatic, though less likely than the 4L60E in a '93 model year.
To know for sure which transmission is in a specific 1993 Suburban 2WD, you'd need to check the vehicle's documentation (owner's manual, build sheet if available) or look at the transmission itself for identification markings.
