P0716 P0717 Transmission Code GM Vehicles

GM has issued a TSB # 00-06-04-037 for P0716 P0717 Transmission Codes to cover the vehicles listed below. The condition could be caused by an intermittent connection in the Input Speed Sensor circuit. The condition is most often found at the 20-pin connector to the wiring harness interface. The input speed sensor produces a signal to the powertrain control module (PCM). If the PCM detects a large change of the input speed signal in an extremely short period of time (less than 0.8 second), it will set a P0716 code and the PCM will direct maximum line pressure. This can result in firm shifts.

If the vehicle is moving at speeds greater than 5MPH and the input speed signal is low or at zero, the PCM will set P0717 and command maximum line pressure.

Do not automatically assume that the input speed sensor is faulty. Instead, thoroughly inspect the wiring harness between the transmission and the PCM. Pay particular attention to the 20-pin connector to make sure it is not stretched tightly. Also make sure that other components are not pressing on the connector body or forcing it open. Check for proper clearance between the connector and other components. Make sure the terminals are fully seated in the connector. Check for bent male terminals or loose female terminals. Also check the crimp on the terminals.

You need a professional shop manual to work on a late model vehicle. And you need access to the latest technical service bulletins so you don’t waste time and money replacing parts that may misbehave due to a manufacturer’s software glitch. Forget about those cheap manuals you find at the auto parts store. They will just lead you astray. Here are the two best online shop manuals around.

Eautorepair.net is really Mitchell On Demand with a consumer style interface.
Get a 1-Month subscription (31 Days) for $16.99, 1-Year (Best Value!) for $25.99, or a    4-Year (Best Value!) for $39.99. I like the wiring diagrams in Eautorepair.net better than the hard-to-read factory diagrams on Alldatadiy. However, Eautorepair.net doesn’t show how to remove trim or door panels. Alldata does.

AlldataDIY.com is simply Alldata with a consumer style interface. They have a different pricing model. But a 1-year subscription for $26.95. Add additional vehicles for $16.95 for a year. Or, buy their 5-year subscription for $44.95. Add additional vehicles for $29.95 for five years.
