NV4500 behind a 6.2

[Mattman2010]

I have a 6.2l diesel with a th400 behind it that I have been thinking about swapping in a NV4500 in behind it for the OD. I was wondering what it would take to get this to work. I know I would need a 85+ Hydro clutch out of a Chevy truck, and a Chevy NV4500. What I do not know is, what flywheel do you need to use? and what clutch? Will a flywheel from a 6.2l with a SM465 work, and then just buy a NV4500 clutch and it will just bolt on?

I dont want to go with a 700R4 because this is a 1 ton 4x4 crew cab, that i plan to haul with, and later down the road I want to swap a cummins into the truck, so swapping in a nv4500 just gets me closer to the goal of a cummins.

I guess another question would be, Will a NP208 from a th400 bolt straight up to a NV4500?

Thanks, Matt

The nv4500 has a different bolt pattern that the sm465. The flywheel from a 6.2 with a sm465 will work with your nv4500. I am gathering parts for the same swap now myself.

As long as it's a chevy bell housing it will work won it?

the nv4500 has a different transmission pattern. it is wider, mine is a advanced adapters bellhousing.

[Mattman2010]

So the stock bell housing on the nv4500 does not have the same bolt patern as all the other gm transmssion to bolt up to a 350/454/6.2/ect?

the motor side is the same as all other gm motors. the side were the transmission bolts on is a different pattern.

Yes I know that, you had me confused. The only sm465 related part I was goting to use was a flywheel. I plan on using the stock nv4500 bell housing.

If you just want cheap manual OD on the 6.2 get an NV3500. It's max torque is 300ft/lb so the 240ft/lb 6.2 will not blow it up in normal operation.

If your final intention is a Cummins engine get the `96+ GM NV4500 unit. The Dodge bellhousing to tranny bolt pattern is the same as the GM internal slave units built 96+.
When you swap in the Cummins you'll need a bunch of Dodge Cummins pieces between the engine and tranny including the Dodge diesel input shaft and bellhousing.

Use a flywheel made for your 82-87 6.2L diesel. Use a clutch kit for a `96+ GM diesel truck.

You need a 32 spline input GM NP208. It will directly bolt up to a NV4500.

The 4x4 TH400 and SM465 mated to the NP208 had 32 spline output shafts.
The 4x4 TH350 and TH700R4 had 27 spline output shafts.

Thanks for the info. The nv3500 sounds tempting for now. As my goal with the cummins is probably a while down the road. Do the nv3500s have 32 spline outputs?

I read here that the fullsize truck got 32 spline and the S10 got 27 spline. They seem to have a low opinion of the S10 tranny.

The NVG3500 Wiki Page has some info but not all.

How would a NV3500 handle pulling trailers and all that? This is a 1 ton truck and I plan to work it. I know the 6.2 is probably not the best option for it, but I also plan on dd it and so MPG would be nice when not towing.

[Mattman2010]

Also, what year NV3500 would I want to look for?
