There are two different types of PCM programmings: those that can control a 4T60E-family transmission, and those that can control a 4T65-family transmission. Therefore, being a 1995, your car should
accept any 4T60-E or 4T60E-HD that fits and plugs in.
Bear in mind if you get one with a different gear ratio, you will need to re-tune, otherwise your shift points will be off by a couple hundred RPM.
