Trans/tcase adapter

Searching only brings up threads from most recently 2013. Is there a current source for Gen III/IV LS to NV35/45/5600 trans adapters? What about either of those trans to LT230 adapter? Figured I'd ask before I spent the time and money.

Check with Matthew Jackson at Advance Adapters 1-800-350-2223, EXT 523

They have developed a bunch of adapters to go between various gearboxes, including the NV45 and the Series transfercase. They might have come up with something that will adapt to the LT230.

I would also talk to Eric at Novak. They made me a custom shaft to mate my electric motor to an LT230 and I know they have built other adapters to LT230.

I have skimmed that thread multiple times but have never sat down and read the whole thing or the other one. I guess I'll have to go through them this week. Thank you.

I don't believe they fit the Gen III engines and I don't know about the Gen IV. I could be wrong though. Another thread I read said they needed an adapter from AA to fit a NV4500 to a Gen III 6.0L.

I thought the only adapter Nick sold was the 6L80E to LT230?

Talk to Nick. As I understand it, he has done a few for the NV4500.

You only need the AA adapter if you want to have an external slave cylinder on the driver side.

You can use a mid 90's Chevy bell housing if you want an external slave down low on the passenger side, or a later Chevy bell housing that has an internal slave cylinder.

I believe the LS series has been used in factory configurations with the NV4500 in both the Gen III and Gen IV engines.

Then if you had you'd find I listed all the parts you need to mate the Gen III/IV to the NV4500 using the AA bell housing. All the research I read pointed to the starter on the Chevy bell hsg hitting the front drive shaft, didn't want to risk that so went with the AA one.

If I did it again, I'd go internal slave with a very good quality throw out bearing. Using the AA bracket and external slave means you can't use the Hooker headers and makes things really tight for the exhaust.

That clarifies things with Andy's response as well. Just found another site listing the LS/NV4500 combo up to 2007. I guess the next step is to find out what power level that version can handle. There was an HD version available for the Cummins engine and V10 models. I'm curious if the LS series input shaft and bellhousing will transfer to that box or if the HD gearset can be fitted into the LS variant box. I'm wanting a manual setup that can handle a lot of power consistently. It would be nice to have a 6 speed in there but I've read today that NV5600 is weaker than the NV4500 and there is a conversion kit available for people to switch from a 5600 to a 4500.

I will go read it fully. How close were you estimating the driveshaft to get to the starter? I'll likely only need room for a single 4" exhaust. So if I can pull that through on one side, I could make it work.

Input shafts can be swapped from any NV4500 Dodge to Chevy to Dodge HD.

Bellhousing too? Do you know if the cases themselves are all the same?

Only differences are the input shafts which are interchangeable, output/mainshafts/5th gear/nut and Chevy vs Dodge 4x4 tail housings...

The anomaly are the early Chevy's 92-94 which were their own animal with a stupid low granny gear first.

Thank you for the info. I found the standard NV4500 is rated to 410 ft.lb. and the HD at 460, hopefully that is enough. High-Impact builds them in any configuration to order, so that could work out well.

After reading both LS threads, Nick's 6L80E adapter works for a NV4500 as well. Thanks everyone. Going to talk with the High Impact guys this week and see what kind of trans we can get built. If that won't work, I'll have to try a Tremec setup with a divorced LT230 or something.
