So what version holds more than 4 quarts of oil? My 29 spline Dodge version also only holds 4 quarts.The 23 spline NV4500 is the light duty version that only holds 4 quarts of oil and has a tiny mainshaft. It's just like the cheezy chevy NV4500 only with synchro reverse.
Where do you get this crap from? Go open up any cummins nv4500. Just pull the extension housing off and wiggle 5th gear and it's nut. If you have an NV4500 and change the fluid in it yourself, ever notice the reddish brown crud inside the tranny? That's not from the synchro or bearing wear buddy, that's evidence of fretting. Fretting is 5th gear, 5th nut, rear mainshaft bearing inner race and reverse thrust loose on the mainshaft and grinding into it. Given time, mainshaft 5th gear will spin on the mainshaft, countershaft 5th gear will wear the countershaft unevenly from being sideloaded by a wobbling 5th mainshaft gear and the rear mainshaft bearing can spin in the transmission case. After this you end up with a boat anchor.Chrysler Corp. put out Technical Service Bulletin 21-10-98 to cover warranty repair of any NV4500 due to 5th gear nut. This recall includes dealership instruction on how to fix. Most Dodge NV4500 trannies should already be fixed because of this TSB. If one was done by a dealership it was to be stamped 'New Nut' on top of transmission case, but not all were stamped.
One transmission company decided to capitalize on this problem and offered their revolutionary, none other like it in the world, finest, coolest, bestest repair kit ever invented. That was supposed to justify their ridiculous price I guess? Anyway, for some reason their extra-superfine repair kit soon became unavailable with little explanation, but lots of BS. Prior to that this tranny shop posted all sorts of extremely negative comments about all the other repair kits, explaining how they were complete junk, and how none were any good, except for theirs of course. They've now backed off some on all the bum-kicking and negative hype, but the damage was done, and not by the 5th gear nut. Far as I know even several years later now, their wonder kit is still unavailable.

You're working on all dodge-4500's right? Just curious, My pops had a 92 2500 with the 4500 tranny. It pulled a 30ft gooseneck for 140k for the first owner then another 56k for us hauling firewood & towing (350V8). Never had any OD issues. Even got submerged once (flooded out) and the motor/tranny held up fine after being drained of courseBTW, better than 1/2 the failed NV4500's I repair are equipped with dodges "super nut". Thier fix is a joke. It doesn't take a genius to realize while tearing down your first NV4500 that the nut is still in the same place it was when it was originally installed. The nut didn't back off. The interferrence fit that's supposed to be there between the mainshaft and 5th gear is no longer there, you can wiggle 5th gear all over the place if your lucky, if you're not so lucky you can spin 5th gear freely on the shaft.
Actually, in my estimation, you're far too much of an egotistical, self-centered and self-proclaimed expert to have a rational conversation with.BTW, better than 1/2 the failed NV4500's I repair are equipped with dodges "super nut".
