Both overdrive automatics, late model 700R4's are controlled by the vehicle computer, but can easily be converted to a manual lockup on the converter.
4L60's on the other hand are completely controlled by the vehicle computer. In order to fit one to your 76 Camaro you will need the computer for it.
========= I believe you mean the lock up converter function is controlled by the vehicle computer in the 700r4 / 4L60's before the 4L60E was introduced in 1993. Early 700r4's used many pressure switches to aid in lockup control, which did not function very smoothly.
The 4L60E is full electronic controlled. All automatic shifts and pressure is controlled by the vehicle computer. You need a stand alone computer to control this tranny.
