Why Doesn’t my Speedometer work after my NV5600 Swap in my 5.9 Cummins?
Guys swapping an NV5600 transmission into their 5.9 Cummins Truck as part of an automatic transmission to manual transmission swap will quickly discover that the NV5600 does not have a speed sensor on it like the 48RE did.
In order to solve the issue of the speedometer not working after this swap (and reprogramming your ECM to a manual calibration); it is recommended you checkout the following resources:
- Dakota Digital Interface: SGI-100BT: Universal Speedometer and Tachometer Interface
- Cumins Forum: Nv5600 swap speedometer help | Cummins Diesel Forum
There are many other pages out there to get info from, but this should get you rolling in the right direction for your swap!
