You will want to look at posts # 9,10,11,12, 23, and 24
Quick Note: You will want to open your glove compartment to do the tests, as it will help you test the connection from ECM to the Transmission at the same time.

Security module is separate?

I was told when looking for a computer for my 95 that the security module is separate from the engine module. If true, it makes things much easier.
