NV5600 shift to 1st gear while moving

[rbattelle]

I find that my transmission doesn't particularly like to be shifted into 1st while I'm still rolling along. Usually, when I attempt to do so there's an audible "clunk" when it goes into gear and the stick tends to push back at me at the same time as the clunk is heard. This is all below 5 MPH. It's as though the synchro isn't doing it's job.



Is this "normal" behavior for an NV5600 with 7500 miles on it?

I haven't ever noticed anything like that, but I'll try it tonight and see what it does.

I have the same thing, and so did my 96 1500, and my 82 150.

I could be wrong, but I don't think there is a synchro on the granny first gear. I know that the best way to get mine into first is to be just barely creeping, or to throw quickly from second to first.

Mine does not like to go into 1st while moving either, and never has. 50,000 miles now and still acts the same.

Thanks, guys. I feel much better now. I had a feeling it was just a characteristic of such a beefy transmission, but I wanted to make sure.

Yes, first gear in the NV5600 is synchronized, but that poor little synchro is spinning a lot of mass (clutch disk, input shaft & gears, etc. ) up to a pretty high speed at any road speed above 2 or 3 MPH. That's why the resistance in going into first when moving.

ALL gears including reverse are synchronized in both the 5-speed and 6-speed.
