NV-4500 rebuild
#2
Built plenty of Manual transmissions .. they come apart one way and they go back to gether one way .. I know that seems stupid to say .. You would be suprised how many times I hae seen a "REBUILT" trans come back because someone forced something where it wasnt designed to fit ...
Get a book and follow the instructions .. take your time, its not that difficult .. Time consuming..... YES !! But I have biult 5Spd - 18 spd and Tripple countershaft MACK tras... WHat A PITA .. Do able though .. just tkes time and lotts of planning ..
OR, Go on E-bay and find one re-built ....

I just did one 2 weeks ago. First time I've ever torn into a transmission. 1600 miles later I have narry an issue.
Pony up for the right fluid for it. Modern GL-5 gear oil is corrosive to brass ("yellow metal") and doesn't absorb right into the CF synchro rings that an NV4500 uses.
Dodge and Chevy both have speciofic part numbers for Castrol Syntorq GL-4 gear oil. It is the ****. it's priced stupidly (something like 35 or 40 bucks a litre here) but it's the stuff to use.
Get a rebuild kit that includes a new mainshaft. you'll probably need it. If the transmission is older than 96, it'll have a multi piece countershaft. pony up for a one piece shaft. nothing will change except the fact that you won't need to worry about pressing off gears or checking anything. in, out.
you'll need a dial indicator. the transmission calls for .006" play on the ends of the shaft, but I set them at .001" on advice from a longtime builder. You're going to be swapping out the fluid if you're changing hard parts after a short wear in period ("your next oil change" was recommended to me) and by then the new bearings will have loosened up a bunch anyway. you'll have to reset them again. Do so.
any other questions, ask away. this is still very fresh in my mind. (and on my camera)
