Somebody told me that the 2nd gear in the manuals had trouble overtime. Is that true? Should I be expecting many repairs on a 5 spd in a 1996 2500. Thanks. Evan
The NV4500 transmission doesn't have any problems that I know of with 2nd gear. The problem is with 5th gear. It is prone to "Falling off" leaving you with only 4 forward gears. To my understanding it usually happens when the engine is lugged hard in 5th gear or when towing loads MUCH heavier then the transmission is rated for. I also understand that the 5th gear falling off does not cause any other damage, transmission just needs to be repaired taken apart and 5th gear reinstalled. There are many fixes that people have come up with over the years but I hear mixed results as to there effectiveness. You may want to speak to someone more knowledgable then myself. In fact I'm putting one of these transmissions into my Chevy Cummins project and could use a little info on this myself. Good luck, I'll be keeping an eye on this post for my own information.

yep, most common issue is from lugging the engine (moreso when its in 5th gear). general rule of thumb is to go light on the throttle while in 5th till your at about 1800rpm, then you can mash the skinny pedal.
Their are a few ways to remedy the issue, like some sort of updated nut (not sure exactly how it differs), welding the nut back onto the shaft or even a whole new shaft.

x2, i'm looking to switch my 97 to a 5 or six spd, and would love to put a gear splitter behind it. anyone know anything about it.. anyone have any .02 to throw in????thanx
With the six I don't think the splitter would be worth the money.
I was going to put a splitter in my 5 speed hauler truck because the rpms between 2nd and 3rd were too much with a heavy trailer. Wind it all the way up in 2nd, shift and almost lug the engine to a stall in 3rd. 3rd to 4th were almost as bad but at least I had some momentum to keep it rolling.
Put in a 3k GSK instead. Solved my problem and was a lot cheaper than the splitter.

The 6spd probably wont be so bad without a splitter but their are times with the 5spd that i find it could use an extra couple gears. (i drag upwards and sometimes over 20,000lbs on the gooseneck)
But a set of gov spings is a hella lot cheaper than buying a splitter. plus the bonus of a little more fun when the trailer isnt hooked up!

the only problem that you might experience is that might be your first synro to go since most people start in 2nd gear. thats the only thing i can see, but you shouldnt have any problems. by the way i am selling my 5 speed if anyone wants it
Don't weld the nut unless you want to buy a whole new shaft! The shaft also will weaken if you weld to it causing more problems than you had in the first place. It is a upgraded nut ( brass inserts and set screws ) I just done this, easy fix bout 200 bucks if someone does it.
