3500 or 4500?

[scottywiley]

Guys, I have a 99 k2500 with 5 speed manual. Would this be the 3500 or the 4500 or none of the above?

thanks for help.

Maybe I'm wrong but I thought 2500 or 3/4 ton. 3500 or 1 ton would be like a dually

If it’s a k2500, it “should be a NV4500, the NV3500 was used in c/k1500 or smaller (s10 etc)

Dang I feel dumb.... my bad. Automatic only over here in this head....

The transmission series is either NV3500 or NV4500. The 4500 is a heavier duty version, but that's about the extent of my knowledge. Other people on here should know way more than me lol

Thanks for the help guys. Sorry Sub. That did look like kind of a trick question after rereading it. My bad.

next question: is the NV4500 a pretty good transmission? I haven’t changed fluid in it or anything. Is that something I should do?

From what I know the nv4500 is a pretty decent trans. They have synchronizer issues in mainly in 3rd if i remember right. They also have a issue with 5th gear but I cannot recall what it is for the life of me. They also use a special fluid and it is different then the NV3500. It is not atf of gear oil. Here is a link that gives the type of fluid and how to change it https://www.dieselhub.com/maintenance/nv4500-transmission-fluid.html
So before you change it make sure which one you have so you know which fluid to buy. Easiest way for me to tell is the 4500's bellhousing is separate from the trans where the 3500 is all one piece.

It’s definitely the beefier version.... if I recall, I know the NV4500s in the Dodges had an issue with a nut backing off causing 5th gear to not engage...not sure if this happens on the GM applications
