Transmission interchange or compatability

Does anyone know if a transmission from a 95 Impala SS 5.7 V8 would fit into a 94 Caprice Classic 4.3 V8?
thanks

why?

Because there is an Impala transmission available if it will swap OK.

Problem is the 94 pcm and wiring lack the Pulse Width Modulation the 95 will have. It can be MADE to work but will not be an effortless drop in. This is a YEAR difference NOT a 4.3l/5.7l or Impala/Caprice difference. An Impala is just another Caprice so year for year the parts are overwhelmingly the same.

Thanks very much for the info
