Start off this is a 99 5.7 vortec mated to a 4l60e and 4.3 atlas. I am using a Painless harness and 97 ECM. I am wondering what people using this set up have done to use the VSS? As far as I know I cant bypass the VSS cause its a 4l60e and the computer needs the info to shift correctly. Painless guy I talk with really did not know any kind of answer So I hope someone with first had experence can help me out.
