Just an FYI to all interested. I just got off the phone with Quigley and they are working with Nissan to allow the newer model to have a useable two speed transfer case. Quigley says they want to use the newer Titan transmission, transfer case and front drive system to allow use of the hi-lo ranges and as of now it's not heavy duty enough to handle the NV. Currently the Quigley conversion uses a front drive system that is heavier duty than the Titan. He said "We have the new 7 speed transmission and two speed transfer case sitting in our shop and we are working on it. Call back in 6 month and see where we are at".
Also just an FYI, my van does have a two speed transfer case but Quigley/Nissan chose to install a removable bracket blocking the lever travel. Why?
Quigley said it's because of two reasons:
1. While in low range, wheel slip causes the van to go into "limp" mode.
2. Nissan was concerned a low range would "promote" vehicle use that the NV was not designed for which may cause vehicle damage that the warranty would have to cover.
