I'm considering buying an '89 Suburban 5.7L with automatic overdrive, but the trans is out of it. The price is VERY reasonable but I'd like to know more about which transmissions will fit as far as different years, etc. and the extent of how much electronic controls there are on these and the potential for problems due to incompatiblity from various years, etc. In other words I'm considering getting a used trans from a salvage yard instead of rebuilding the one it already has. I presume it is a
700-R4. Any input appreciated.- posted
