I have a new 2008 automatic and has anyone noticed when you push on the accelerator, it has a 1-3 second delay before it starts going. I mainly notice it while cruising down the highway and try to speed up. Then it will down-shift and the motor will race up. Also when I put into reverse, the rpms drop to about 500 and stay there. It sounds like the motor is going to die. Is this normal, are your trucks doing the same thing???
