nv4500 swap

[manostihl]

Looking into swapping a p pump in my truck and a new turbo and im pretty sure the ol getrag isnt going to handle the upgrades i plan to throw at it plus I've never liked the gear spacing.. What all am I going to need to swap my 4wd Getrag out for a 4wd nv4500. Flywheel the same? What about the t case?

The Getrag will handle just about anything you can throw at it...and the gear spacing is pretty much the same except overdrive, 0.77/Getrag, 0.75/NV

As for the NV swap, you can go two routes. Use all second gen parts or get the Advance Adapters kit. I used all second gen parts, as in block plate, bell housing, starter. Your pedals, hydros and transfer case will work with the NV but you'll have to do a few things. The output seal in the NV rear housing needs to be pulled out for clearance, the transfer case coupler will occupy it's space. The transfer case has a good input seal so you won't have to worry about the two different fluids mixing. I made my own transfer case shifter bracket, as you'll need to either buy the AA style, or make your own. You'll need some sort of transmission mount, again, made my own out of 3"x3" 1/4 wall square tube, about 8" long. I used a new clutch and flywheel, so I am not sure on that part...

Really? I've heard nothing but bad about the getrag. Mine sure did growl loud whrn you get on it in 3rd and fourth with my nearly stock minus pump tuning and injectors non intercooled 12v.

Sounds like your Getrag is due for an overhaul then. The saying is "If it's making noise fix it before it gets expensive!".
I'm running over 400hp and about 850lb of torque thru mine on an almost daily basis in the summer months. It drives to Iowa every spring and usually Indiana in the fall. Last fall it went the other side of St Louis since the meet changed locations. It rattles when it sits in neutral, but it has done that for 3-4 years with no ill effects yet.

Well mine was rebuilt before I got it or at least supposed to be it does have a tag on it from a shop it only growls when you romp on it hard

They might have put a tag on it. That doesn't mean they knew what they were doing. If it is making noise it needs a rebuild.

Swapping from a getrag to a NV4500 is a side step not an improvement. Both trans has problems. A quality rebuild on your getrag would be cheaper than another trans you might need to rebuild after install.

Ain't that the truth....that is why I like to do as much of my own work as possible. I can screw things up myself...don't need to pay someone to do it for me.

My guess is whoever "rebuilt" the trans either used cheap bearings, or did not set-up the end play properly. If you don't set the end play right...getrag or NV...they will not last long....maybe 25K miles or so?

its made the growl ever since I got it. I haven't been easy on it really and I've even towed with it. It hasn't blown yet lol. I always do my own work piss on paying anyone else unless its machine work

Mines always clang-a-langed the 3 years I've had it, and it was 1 owner with 145k.

It only had 3 qts in it when I changed the oil, so I'm sure it'd never been overfilled. Has a 5th wheel so I bet it saw some weight......
