Nv4500
 

what is the shortest nv4500 to use with a divorced t/f case. the dodge 2wd looks longer than the chevy 2wd? Would like to use my stock bell with an adapter. a chevy with the dodge in put?

Re: Nv4500
 

I think a chevy with a dodge gas input, then you could use an A/A adapter and keep the cast iron bell, but it woul have to be bored out to 5 1/8. Or have your own adapter made. I have a cast iron bell with 5 1/8 bore already and this is what i will do some day.

thanks for the reply--must be getting old, thought i put this in the 4x4 section not the 4x4 builds.

Re: Nv4500
 

Another member on here was successful in in doing a transfer punch from his bellhousing and drilling new holes in the nv4500 case. He was using a later aluminum bell, so as dieseldude said youd also have to bore out the center hole to fit the nv4500. This would allow you to just bolt on a chevy nv4500.

The 92-95 chevy housings use a different bell bolt pattern than 96 and up chevy, and dodges. Luckily since you are using a 2wd version you wont be concerned that chevys have 32 spline outputs while dodges use 27 spline.

You might also give thought to swapping the T221 out for a Dodge divorced NP205. It would be quieter and parts are far more easy to come by.

I've looked at them and I think you could do it with simple mods to the 221 mount brackets. It would however increase your rear driveshaft angles.

The gm 2wd fixed yoke 35spline has a 6" tail housing which is 7" shorter than the dodge version.

I have the some pics of this set up ,I will post them when I find them.

As argonaut suggests, the early GM NV4500s used a trans bolt pattern the same as earlier manual transmissions. They also have an unsynchronized 1st like the SM420 and SM465, while the 96 up had a 5.6:1 or so 1st, which isn't much different.

Re: Nv4500
 

wait, I want to correct something. I have both a 92 and a 95 chevy nv4500. while this pattern is different from the late pattern, it IS NOT the same as the early chevy 4-speed patterns.

Also the output spline counts that I listed were for 4wd transmission outputs, not 2wd. So those may not apply.

Re: Nv4500
 

Thanks for all the info--so a chevy 2wd with the 6" tail, what is the total length?

Re: Nv4500
 

Here is the pics of the Nv4500 I installed in the dodge power wagon.

Re: Nv4500
 

Crew-- that looks pretty short, any measurement (total length) specs. of trans? and thanks for the pic.

Re: Nv4500
 

The Nv4500 main case is 12.375" plus the Gm 6" fixed yoke.

The Nv4500 in above pic.

Gm 96 and newer,w/Gm shifter stub.
Fixed yoke 6" ,w/35 spline output.
Cummins input and bearing retainer.

I use this set up in all my Cummins conversions when I need a divorce t-case or in any2wd.The E-brake drum can be added as well.

Hope this helps.
