Shifting into neutral

Hi Everyone...

Thanks(?) for all the replies. I was kind of hoping someone with this actual truck who's done this before would chime in. I didn't realize quite the can of worms I was opening when I asked.

Regardless, I found this elsewhere:

Another neat trick is that if you're going down the road and you shift into neutral, the engine wont drop down to idle...the TCM has whats called "neutral tracking", meaning it will automatically raise the engine speed to the proper "rev-matched" speed, so when you move the shifter back into drive, the engagement from neutral to drive at X mph will be smooth and rev-matched so theres no huge clunk.

So, it does in fact seem that it's supposed to do this.

Thanks for everyone's concern. I'll stop being public highway enemy number one now, and leave it in drive. ;)

Opening a can of worms is not to hard on this forum :W
Interesting information with the RPM. I suppose if you were doing 80 MPH your tack would be even higher then :H I did think of that afterwards, that low idle RPM would be a killer on the TC when you did shift back to drive , thus the big CLUNK.
Interesting but lets just say I ain't going to try it out for an example for this forum :B Heck my Cummins always feels like it's in neutral down hill without the exhaust brake on without a manual downshift, even then it's weak at engine braking without the EB.
