Bolt-on plate and double-D lever that replace the electric shift motor on an NP273 transfer case so you can shift 2WD, 4HI and 4LO by hand.
The NP273 is shifted by an electric motor that bolts to the side of the case and turns a double-D shift shaft. When that motor, its encoder or the 4WD control module fails, the truck gets stuck in whatever range it was in, and a new motor plus diagnosis is not cheap. This kit takes the motor out of the picture and lets you turn the shift shaft by hand.
It is a five-piece kit: a machined aluminum cover plate that bolts over the motor mounting face and seals the opening, a steel lever with a double-D bore that slides onto the shift shaft, and three socket-head cap screws to mount the plate. Nothing is cut or drilled.
Installation: unplug and unbolt the shift motor, clean the mounting face, fit the plate with the three screws, then put the lever on the shaft. With the truck stopped and in neutral, rotate the lever to move between ranges. You can operate it at the case or run your own cable or rod linkage to it. The dash 4WD indicator and switch will no longer do anything, so expect a warning light or code on some trucks.
This fits NP273 cases with the double-D shift shaft, the electronic-shift case used in Super Duty and Excursion applications. Check that the tag on your case reads NP273 and that the shaft is double-D before ordering; an NP271 manual-shift case does not need it.
