P0716 on Buick by model: symptoms, diagnosis and fix
First-generation Enclaves (2008-2017) use the 6T70/6T75 6-speed automatic, whose stamped-steel 35R wave plate can crack at the teeth after enough shift cycles. When it fractures, the transmission abruptly loses 3rd, 5th, and reverse gears, and debris can damage the valve body, drums, and torque converter. Failure typically occurs in higher-mileage 2008-2012 builds.
Common Symptoms
- Sudden loss of 3rd, 5th and reverse gears
- Slipping or no movement
- Harsh or no shifts
- Check engine / transmission warning light
How to Fix
Disassemble and rebuild the transmission with an updated/stronger wave plate, plus replace damaged hard parts and clean out debris; in severe cases a remanufactured unit is installed.

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 Buick it is documented across 1 model: Enclave.
