GM Truck Throttle Body Injection 4.3, 5.0, 5.7, 7.4 Engines 1991-1994
(using the 4L80-E Automatic Transmission)
GM added a computer command automatic transmission to the truck engines first and later years to their passenger cars. While the engines look the same and use most of the same sensors as the 1985-1990 engines, the older ECM's do not have the capability to control the electronic transmission. We incorporate the wiring necessary for the electronic transmission. The CK truck ECM will be used in this application. The transmission types available were 4L80-E and manual transmissions.
