Transfer Case Shifter Kit - 4L80 / 6L90 to NP261
This is a simple bolt-up solution for a 4x4 transfer case shifter assembly that works with either the 4L80 or 6L90 transmissions found in most 2003-2021 model Express and Savana 2500 + 3500 series vans.
The shifter linkage is intended to tuck tightly against the driver's seat for easy access and to keep the "aisle" clear between the two front seats. (Some models may require shaving or trimming the seat tilt lever for clearance) We have also used the same linkage on cab/chassis variants like school buses and it works fine for most of them as well.
This is a basic design that was put together for usage with our transmission adapters and the NP 261 case, however, it can be modified to work with other designs by modifying the length of your connecting rod.
We have made a handful of updates to this product since photography (additional gussets, modified pivot), so the actual product may look just slightly different.
We have (2) shifter boot options available for this product. The premium version is significantly easier to install, particularly on late-model vans.

This product may work with other model vehicles.
During install: There are often wires in between the two front seats, under the carpet!!!
No cut-template is provided, the best solution is to pull the interior trim back first and make sure the area clear of wires, then mock up the unit and lever under the van, make a small hole to push the lever through, connect the shifter rod to the transfer case, then work the lever back and forth as you increase the hole size in the floor to accommodate the travel.
Once the hole in the floor is fully clear, you may trace the under-side of the interior trim and cut accordingly. This ensures the smallest hole possible and the least noise-feedback in the cabin....and the least likelihood that you will cut into a vehicle harness.
