The PCM's are different.

Technically since 2003. I have a transmission pretty much like yours. They were going to swap body styles in '03 but figured...well lets just throw the transmissions in them instead. Hence why you cannot use a '03 PCM in any other car. Puts the transmission into Limp Mode and keeps you in 2nd gear all the time...its fun.

That's what I thought too but I hear it's more than that.

So the 2003 transmissions are EXACTLY the same?
