Yes it will bolt on, but it will not function correctly. The 3-2 downshift solenoid has a different resistance on the '96 on up transmssions and the '96 has a PWM TCC solenoid in the valve body, where the '94 uses a on-off TCC with no PWM functions. The '93-'94 4L60E is kind of a bastard child transmission, only those years will interchange directly. I am sure there are ways around the electronic issues, but if you are looking for a bolt and go, not gonna happen. Is the '94 LT1 4WD by chance? If not, you will have to change the output shaft in the transmission, and then you may as well rebuild the '94 transmission at that point!!!
Hope this helps!
Mike
