We replaced the transmission with one from a 2006 silverado. Wiring
is all the same the only thing we had to change was the park, neutral
position switch. The problem we have is the trans will not up shift
and the speedometer is not registering. The ABS and Brake lights also
came on and they weren't before the swap. ANY suggestions would be
great as I am lost to this point.. thanks in advance.
the VSS the same? I think a 99 is looking for a 4K VSS signal but I don't
know what the output is on a 06. Might want to swap in the VSS from your
original tranny. My opinion is either a wrong VSS, bad VSS or maybe you
stretched and broke the wires to the VSS.
Keep in mind I am not fortunate enough to be looking at factory manuals.
Pulling it off the top of my head. There could be other problems. Have it
scanned, find out if there is a VSS signal. On a 700R4 both mechanical and
optical VSS's were in the T-case. I THINK they were moved to the tranny body
just in front of the T-case/tailshaft flange on the E models. If the VSS
output is diffrent, IF, it won't change with a sensor change, you have to
swap the reluctor ring or the buffer. I may be way off but its something to
