I recently purchased a 2002 Ram2500 4x4 with the 6 speed. There is a slight grind on the 2/3 shift for the first few miles even with the outside temp in the 70's. The truck has 32k miles on it so it should be broken in by now. Does anyone know if DC has a fix for this or should I even bother with the dealer? It's still under warranty. Would a different type of gear oil help?

 

camelracer,
That is pretty standard for the NV-5600. It is not the smoothest shifting manual around. Lots of people try running a synthetic gear oil in it. The most popular one seems to be Redline MTL. I have run it in my truck for about 2 weeks now, seems to help a bit.

Yep, put MTL in it, should help. Jack the rear of the truck up as high as you can get it so you can get all the oil in (9.5 pints) Take the PTO cover off and clean the magnet also.

REDLINE MTL REDLINE MTL (now repeat).
Its available online cheap at www.synlubes.com

i used redline and it was a great improvement. a lot smoother.

but if you still have warranty be careful. i believe others have said some of the dealers wont warranty the tranny if redline is in there. legally, they would have to because redline meets and exceeds the properties of the DC tranny oil but you would have to battle.

just go for it and be happier, Pat

 

2002 models have a 7year 70,000 miles drivetrain warranty and is transferable.

 

Depends on when you bought your 02 mine has the 3 year 60 000km.
