Ok, so I think it is a Doug Nash unit. It has a Dual Range badge with 'DNE2' in the middle, I need to get some pics in the day light. I can't get it to shift smoothly, it always clunks HARD when up shifting or down shifting with the splitter button. Maybe I just don't have it figured out yet.. Is there is video of shifting with a doug nash unit??
Makes sense, and Doug Nash and U.S. Gear are essentially the same. U.S. Gear bought the design from Doug Nash and made some modifications to the internals and to the shifting motor/electronics, but they're basically the same unit. As to how to get it to shift more smoothly, I'd love to hear more on that myself...
He's in California, there is no speed limit!
I WISH that were true!! Actually, in urban areas, speed limits aren't needed because traffic's never moving anyways
Wow, 75 MPH at 1600 RPM... And I dream of getting back to the 70 MPH at 2000 I'm used to with a ZF5. Can one of these boxes go behind a 4x4 ZF5? What does it take to get power from an IDI to comfortably run at 70 MPH in double overdrive and presumably around 1500 RPM? MPG unloaded?
Unless you start getting creative with mounting a Brownie box (it's been done!), you basically have two choices...Doug Nash/U.S. Gear and GearVendors. Mitchell made a splitter that can be used with any transmission (it replaces the carrier bearing), but they're difficult to find...Advance Adapters also makes a splitter, but it mounts between the bellhousing and the transmission, so it can really only work with a T-19.
For a 4x4 application, a Doug Nash or U.S. Gear unit mounts between the transmission and the transfer case, and the GearVendors unit mounts aft of the transfer case, so you can only use it when you're in 2H. The GearVendors unit shifts much more smoothly, and they're still supported by GV (for that matter, if you have the $$ to burn, you can buy one new); however, I've heard that they don't take well to engine-braking even if they're not engaged...
