Well, the trans in the 94 isn't a 700. It is a 4L60E. Same hard parts as the 700R4, but computer controlled (same computer as the LT1). So, you need to figure out the pulses that the dash needs, and the signal that the PCM (computer) puts out from the trans. If you're lucky, they are the same. If not, you will need a box to convert the signal to what the dash needs. You can get that from a few sources (like Jags That Run).
