I have a 68 camaro rs with ls6 zo6 motor and 4l60e trans , prob i am having car will not down shift all the time , some times i come to a stop and car starts in what i think is third gear, if I un hook battery it will start in first gear again, well anyway, when hooking up to scanner to see if solenoids are working. i notice the rear 02s are soposed to be tuned out because I dont have any. They are reading 450 something and dont move is this normal? Do they just put a # in ecm to trick it . Prob i see is that right side bank one is at 937 at idle left side bank one is only at the 450 with the rears that are soposed to be tuned out, Any ideas? The left side 02 wouldnt put ecm in limp mod and cause trans to act up?
