Not easily. The LSx PCM is not compatible with '94 or '95 4L60E. The '94 is non-PWM for the TCC solenoids and all '96 and later PCMs are designed for PWM TCC.
The '94 used a PWM 3-2 downshift solenoid and '96 and later PCMs are designed for non-PWM 3-2 downshift solenoid.
It might be possible to disable some codes and change TCC tuning, but I have not read of anyone successfully making these electrical/tuning changes.
More significantly, your '94 is probably tired with many miles; the LS engine will shred it.
