I think the nv4500 is a hair longer, maybe 1 or 1 1/2 inches IIRC

When I was looking for an nv4500 the cheepest one I found was $700 and that was used. Seems like folks are proud of them. I picked up my 465 for $50 and that was with a hydro bellhousing.

I am in the process of doing this exact swap.

There are two different style of GM NV4500's. They are:

92-95 has a 6.34:1 low, unique bell housing bolt pattern to GM, and a bottle top aluminum shifter. Reverse gear is not syncronized

95-up has 5.61:1 low, shared bell housing bolt pattern with Dodge, new square shift top, reverse syncronized.

ONLY 4WD VERSIONS WILL WORK. NO 2WD!!!


NV4500 stock bell housing will not be able to be used in 73-87 trucks since the hydraulic clutch slave cylinder is on the passenger side. It will interfere with the drive shaft. SM465 bell housing will not bolt up. You will need to use an Advance Adapters Bell Housing.


First, you must know if your engine is pre-1986, or post-1986, as the crank area is different and is addressed in the different versions of bell housings available.


For the 92-95 version, you will need Advance Adapters 712577 Bell Housing and should you choose to use hydraulics instead of mechanical linkage, you will also need Advance Adapters 715535 Slave cylinder bracket. I believe their bell housing will work with the mechanical linkage. You need to call them to confirm.


For the 95-up version, you will need Advance Adapters 712576 or 712586 Bell Housing. Same issue with the linkage applies.


Click Here for Advance Adapters Transmission to Engine options.


If you choose to go with a hydraulic set-up, you will need:

1986 Clutch Master Cylinder- Dorman CM39732
1986 Clutch Slave Cylinder - Dorman CS37791
1986 Clutch Hydraulic Hose - Dorman H38559
1985-1987 Hydraulic Clutch Pedal Assembly (mechanical pedal can be modified)



GM NV4500's are 10 spline input, 32 spline output. Any 32 spline 205 (circular), 208, 241 and 243 transfer case, passenger side drop, will work.



I got my NV4500 through All State Gear here in San Antonio. Contact David and let him know I referred you. He'll cut you a great deal. www.allstategear.com


You will need to get the shifter boot assembly and shifter for the transmission as well. GM to GM only as they use a different thread than Dodge.


Cross members that will work are the single hump or double hump from the late 70's and mid 80's. The straight across will not work with this application.


Back up switch plugs are compatible through 95.


You will need to modify the center hump in the truck as the SM465 shifter is forward on the tranny top, while the NV4500 is rearward on the tranny top.


No driveshaft modifications should be necessary as the SM465 and the NV4500 with their respective t-case adapters are only 1/2" in difference (NV4500 is longer).


Per Advance Adapters, clutch should be 11". If you have a 12" as I have, you will need to check fitment. Grinding of the bell housing may be necessary to fit the 12" or high hat clutches.

Here is an article on doing this swap:

Hope this information helped you. If I missed anything, I'll update.

This is good info, But my experience has been that the 205, even with a circular pattern, still needs an adapter to gain clearance for the shifter. Advance adapter # 50-6910.
Hope this helps somewhat.

Man I was way off. Novak lists the 4500 as almost 7 inches longer than a 465. My bad.

I probably have about a 1k in the swap for everything. It's well worth every penny though. The gearing split is much better and I have overdrive so I can run lower gears in the axles.

i am using a late model 4500 with a 205...no adapters necessary, just some grinding to the stock 4500 adapter and a custom shifter mount..its real easy to make one out of strap steel. I am using the internal slave with the stock 86 chevy master....I have the wrong clutch installed right now though, the stock 86 clutch is different than the internal slave clutches are welder

Whats the point in doing this if he has a good solid tranny. Just to gain the 5th gear.

I got allmost $2g's in my nv4500 swop.But mine started off as 2wd diesel trans. Plus i only wanted dealer parts only to. But i put mine behind a dodge 318ci magnum. After i blew 3 nv3500 trannys in 2.5 year. 300+hp x 37's well tear so stuff up on the street.jamminzz

ramrock your right the tranny i have now is rock solid and i have no problems what so ever, but i would like to have more choices with my gearing and rpm range. now 1st gear is almost useless driving anywhere, 2nd and 3rd are too big of jump in between to grab a gear if its not just the right rpms, and 4th is overkill overdrive lol. maybe im just being difficult. my truck is a weekend truck i drive it on street and offroad, it has a built stroker maybe throwin 475hp from what i can remember from dyno, runnin 40" hawgs and 4:56 gears. eventually i plan on gettin 4:88, and i think i will will like my gear selection better with a 5-speed. too bad i cant figure out how to put a 6 speedwelder1funny1

The 5 speed will really wake that engine up. Even with a big block the 2-3 split was horrible. Although not real great with the 5 speed, it is a lot better now. It's also easier to shift with a closer pattern. Not to mention the overdrive.

This is with the early chevy transmission though. I have driven a 97 dodge with the 4500 behind a cummins and the 2-3 split was horrible, but they used different ratios.

Now if I could just put a dodge g-56 behind a BBC that would be a nice setup.
