It's usually best to go with what the vehicle was designed for .

It will not. The 1997 is OBD II but the 1994 is OBD I. They're completely different computer control systems and are not compatible with each other at all! A 94 and older should work but make sure the tags on both transmissions match. Also, stay away from a 1995 model. They can be either OBD I or OBD II. Hope that helps! Jim
