Notchy Gearbox
I have an early '04 3500 with 6 speed manual and Southbend clutch. I am pretty sure it has the NV5600 in it. Anyway, the gearbox is extremely notchy and sometimes will not go into lower gears, and hard to get in higher gears at times. Has anyone experienced this with their truck? Will switching fluids to Redline MTL or Amzoil help this problem? Is so, which one should I use? Any help would be appreciated, Dave.

Mine shifts notchy when hitting 3rd, and it can decide it doesn't want to go into 1st or reverse after it's been idling.
Redline MTL helped some, but I've talked to other folks with the NV5600 and I think that some of them just don't shift very easy.

I have to go to third or 4th and than back to 1st after idling, I think that is nornal. When I am rowing the gears I just "open palm" the shifter from second to third because the shifter will center in the 3rd/4th gate automatically.
