Circuit checks should be taken between the shift solenoid control and the PCM itself using a voltmeter. The solenoid itself should be checked out for possible signs of disconnection or fault.

How does a mechanic diagnose the P0976 code?Ī mechanic can first identify the P0976 code by reading it via an OBD-II code reader. A trouble code and illuminated dashboard engine lamp will be present as well in order to help diagnose the issue. The transmission system may otherwise act erratically, depending on how severe the solenoid control circuit malfunction is.
One or more gears may be inaccessible due to the solenoid control circuit malfunction. In the case of a P0976 trouble code, the vehicle may suffer gear slippage or a failure to shift. Although this should only be considered once all other options have been extinguished, it is nonetheless something that may be considered if every other code-related component checks out properly. There is a very small chance that the PCM itself is faulty and reporting a false issue. Technicians report that the code is often the result of a vehicle being stored under poor conditions for too long, or otherwise poorly handled in a previous set of repairs. Issues with a broken electrical circuit between the solenoid control circuit and the PCM are the most likely cause for a P0976 trouble code. In the case of a P0976, there has been a reported lack or shortage of voltage input being fed into the PCM, This may result in a host of issues for the vehicle's transmission system. The shift solenoid control circuit helps to relay voltage and input between the shift system and the PCM. This master solenoid and sensor kit fits the following years: 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, and 2010.The P0976 trouble code indicates that the Powertrain Control Module (PCM) has detected a voltage from one of the shift solenoid control circuits that falls below the set parameters outlined by the vehicle's manufacturer. This transmission is known by the following model names and number: 4T40, 4T40E, MN4, 4T45, 4T45E, MN5.
This electronics overhaul kit fits the following Buick, Chevrolet, Daweoo, Oldsmobile, Pontiac and Saturn applications: Output speed sensor – will fit all but the Pontiac Sunfire.
