P0716 on Chevrolet by model: symptoms, diagnosis and fix
Equinox models with the GM 6T70/6T75 six-speed automatic suffer shudder, harsh or delayed shifts, slipping, and loss of reverse. A common root cause is failure of the 3-5-reverse wave plate, which can crack and cause extreme shudder when reverse is engaged and eventual loss of drive. Overheated/degraded fluid that loses viscosity accelerates internal wear. Failures typically appear between roughly 60,000 and 150,000 miles. Owners report bucking when engaging gear, failure to shift out of 2nd, and inability to engage reverse.
Common Symptoms
- Shudder, especially engaging reverse
- Hard or delayed upshifts
- Slipping or failure to move from a stop
- Stuck in gear / won't shift out of 2nd
- No reverse engagement
How to Fix
Service the fluid on a strict interval (and after any overheating). For wave-plate failure, the transmission must be removed and rebuilt with the updated/stronger wave plate; a fluid-and-filter service alone will not fix a cracked wave plate. Verify a current 6T70 software/calibration update is installed to address shudder/shift quality.

Frequently asked questions
What does P0716 mean on a Chevrolet?
P0716 stands for "Input/Turbine Speed Sensor "A" Circuit Range/Performance." This code means the input/turbine speed sensor is producing a reading that is out of the expected range or is inconsistent with other data. This sensor tells the transmission control module how fast the transmission input shaft (turbine) is turning, which is used to calculate gear ratios and time shifts. An erratic or out-of-range signal can cause harsh shifting, incorrect shift timing, or the transmission entering limp mode. It is often caused by sensor, wiring, or fluid issues. On Chevrolet it is documented across 1 model: Equinox.
