Hi All,

I don't think it changes anything but line pressure through resistors.

I spoke with the tech line at B&M, and they said it would not work post-98. He didn't say why. I don't think he knew either. Instructions said 94-98 and that's all he had...

That's sort of the response I figured I would get if I called them. I'm hoping that someone here has tried it on a 1999 trans and knows if it works or throws codes. I know my PCM has the newer HO code but I don't know in what years this code was available. If only in the 1999 PCM then it not working might be related to the newer code. Anyone know?

Thanks for the input,
Art.
