If that 700R4 was attached to a mechanical engine (or even a TBI engine, which only had basic electronic functions), it's not going to work... there's no engine ECM for that transmission ECM on the 4L60E to interface with.
700 R4, the better way to tell is when the down shift cable is no longer present the transmission shifting is computer controlled 4L60E which is a more complex (computer controlled) version of the 700 R4. I looked at a 92 today and it had a 700 R4.
Most likely if it is an automatic it is a 700 r4 in the 92 camaro. It will fit but the 700 r4 doesnt have the torque ratings of a 4L60 or 4L60e that came in the 94. Depending on the torque output on the z28, you might end up blowing up the 700 r4. So your best bet is to get a 4L60 or have the 700 r4 rebuilt and "bulletproofed".
They both are the same.
700 R4 transmission.
700 r4
Th-700 r4
700-R4
most hace the 700 r4
If it is a 4 speed automatic with OD it may be a 700-r4
700 r4 also known as L60 transmission...
700 R4 if it is automatic. 2x2
that would be a 700 r4. realistically any small block chev transmission will work the 4.3 is a 5.7 with the front 2 cylinders cut off but the 700 r4 is what you need and only a 4x4 one will work.
