Hi guys, I have noticed a "slack" between pressing the accelerator and the wheels actually turning. This is most prominent when the truck is already rolling and acceleration is added. The transfer of power to the wheels can be felt as a "jerk", and heard as the wheels engage. This has happened after coming to stops and going again, but rarely.

I would say 80-90% of the time acceleration is smooth without the "jerk", 99% smooth acceleration after coming to a stop.

Thanks

p.s. I promise this is not a case of lead foot.

 

My dad has an '05 WK 4.7L and I've noticed this when I was driving it. The transmission makes a "growling" noise as well, which as I understand can be normal. We had the transmission flushed and refilled with fluid, the gaskets replaced, and the solenoid replaced. It seems to have improved on the "slack", but I haven't driven it much since the service was done to it.
