Wanted to get TSB 18-004-04 for my truck. Dealer still could not enable high idle feature. They printed the TSB & showed me that it was only applicable to auto trannys & not the 6 speeds.

Is there anything out there for the 6 speed?

 

I have a 04.5 with the NV5600 and my high Idle kicked in the other day. It was running for about a minute before it kicked in. It ramped up to about 1000 RPMs.

 

I think he was talking about the adjustable version thru the cruise control, not the cold weather warm up. And, unfortunately, there is still nothing for us handshakers as far as an adjustable one.
