4L80 vss signal - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello all,

Has anyone converted to an electronic trans (OD) from the original 350/400 turbo? If yes, what did you do about the VSS?

I am running a 4l80 with a MSD controller. The motor and the trans run fine but my idle has been erratically high. A guys at "gearheadEFI" said the original PCM needs the VSS for some reason to idle right.

If you made this swap, how did you hook up the original VSS to the 4l80?

Thanks,
Chris
