Shifting into neutral
Hi everyone,
I'm fairly certain this is "normal," but since diesel trucks are new to me, I figured I'd ask.
I have a 2008 Chevy Silverado 3500 Duramax w/ the 6-speed Allison transmission.
Last night, I was driving home at about 60-65 mph down a very slight grade, but downhill nonetheless. I was not towing or anything like that, just driving.
So, while in drive with my foot off the accelerator, my RPMS were in the 900-1000 RPM range. When I shifted into neutral, however, the RPMs went up to ~1200-1400.
This surprised me, as any other automatic I've ever owned, shifting into neutral brought the RPMs down to idle speed.
It didn't seem to hurt anything, and I just shifted back into Drive and carried on. I just want to know if that's, indeed, 'normal' behavior in a truck like this.
Thanks!
Matt
