Description
Transfer Case Speedometer Tone Wheel - 49 Spline | 1998 - 2007 — 25902
This is a replacement rear output speed sensor tone wheel for GM transfer cases with a 49-spline mainshaft; NP261HD, NP263HD, NP261XHD and NP263XHD.
The speedometer in your vehicle receives signals created by the speed sensor’s magnetic pickup interacting with the peaks and valleys of the tone wheel to accurately indicate vehicle speed. If there is an issue in the speed sensing circuit it can cause the transmission to go into “limp” mode in an attempt to prevent additional damage.
