What? Maybe I'm misunderstanding the coversation, but 50k miles until you have to rebuild your transmission?

Now i'm a bit worried. I have 255k on my stock (i think) 5spd.. should I start worrying about a replacement trans?

you folks that go through nv4500 need to either learn how drive a standard, get the right fluid or just quit makin so much power... cause 3 of my family members that have nv4500s in there dodges have all 3 gone over 250,000 with out a rebuild. 1 is a dailydriver, the other 2 are farm houling trucks, a;; 3 4x4. 1 hasnt even ever had a clutch replaced yet and its over 270k. i know my truck only has 97,000 on it and i just replaced the clutch, i had new bearings and sycncros installed to even though it was all fine in there and drove good. i fully expect this tranny to last at least another 100k

we work the **** outa ours. 35,000 lbs gross is a light load and we dont hold em back. but $1250 dollars a year for repairs isn't too much anyway.

1250$ to have a shop rebuild the entire trans? Or for one of your guys to rebuild it?
