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 ****ft
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.
