Review on Dorman 599 251 Reman Trnsfr Module by Nolan White

available So happy I tried this thing. 4X4 didn't work. Keys pressed, no gauges, no gauges on the dash, nothing. Replaced this block behind the glove box in about 15 minutes and now everything works! Another version is the Motorcraft TM153 which is also meant to fix 4x4s. TIP: Squeeze the sides of the glove box to lower it for easy access to this module. A screw on the bracket secures it to the fan housing, then simply use the bracket with a new module. Simple solution!
