Circuit Description

WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The transmission internal mode switch (IMS) is a sliding contact switch attached to the selector detent inside the transmission. The IMS is used by the transmission control module (TCM) to detect the angular position of the shift selector shaft. There are 5 internal switches in the IMS, A, B, C, P, and NS. The TCM uses 4 of these switch inputs to determine the proper gear range that is selected. The fifth switch, NS, located in the IMS, is used as confirmation that the transmission is in NEUTRAL before the engine starter is engaged.

DTC P0706 is a type A DTC.
