How to check your GMC Sierra 1500 transmission?
Clean the air flow sensor also, check the minimum air rate, reset if needed, then reset the ECM and roadtest if the check engine returns with the same code, check the ECM’s sensor voltage to that sensor, if the ECM’s voltage is at 5 volts or just slightly below at the sensor then check the sensor ground if it checks good then replace the sensor.

What kind of transmission does a Silverado 1500 have?
When diagnosing a shudder vibration condition on some 2016-2018 Silverado, Sierra; 2016-2020 Tahoe, Suburban, Yukon; 2019-2020 Silverado 1500 and Sierra 1500 models equipped with 5.3L V8 engine (RPO L82, L83, L84) and 6L80 6-speed transmission (RPO MYC), it’s critical to determine the source of the vibration in order to make the proper repairs.
Why does my Silverado 4L60E have lame shifts?
Apparently on the newer trucks the engineers re-designed (un-desinged?) the 4L60E so that it has incredibly lame shifts. The converter never really locks up like you would think. There’s something called Pulse Wave Modulation (PWM) used to make the converter lock-up almost undetectable.
Can a car shift gears without a downshift solenoid?
Downshift solenoids are an important transmission component, and without them, the vehicle will not be able to shift gears properly, sometimes even to the point of rendering the car undriveable.
What causes lack of pressure in 4th gear shifting valve?
A leaking O-ring will cause a lack of pressure to build up and shift the appropriate valve delivering pressure to the TCC solenoid or the 4th gear-shifting valve. A sticking check ball, corroded, worn out check ball will likewise cause similar problems.
What does it mean when your transmission Cant shift into fourth?

What to do if your Silverado shifting is bad?
Sometimes it might require a re-calibration load by a dealer; that will cost if off warranty. And sometimes, it could be solenoids that the computer controls are bad, or a hard part inside the trans is bad. Really hard to diagnose from a recliner hundreds of miles away.
Why is my shift gauge not working on my Chevy Silverado?
