P0882 means tcm power input signal low. The ECM saw a value or response outside its calibrated window for the transmission system. Real-world fixes usually start with the highest-probability cause below for your year, make, and model - not a parts-cannon guess.

Diagnose It
1Confirm P0882 is current (not history-only) and save freeze-frame RPM, load, and fuel trim.
2Inspect connectors and harness for the listed sensor/actuator before replacing parts.
3Command the actuator or graph the sensor live with a scan tool; compare to known-good values.
4Fix the root cause, clear codes, and verify monitors complete on a mixed drive cycle.
FAQ
Can I drive with a P0882 code?
Park it if power is cut, shifting is violent, or the light is flashing - short trips only if it still drives normally.
How much does it cost to fix P0882?
DIY parts typically land around $80-$450. A shop diagnosis plus repair commonly runs $250-$1800, depending on whether it is a sensor, harness, or major component.
What is the most common cause of P0882?
Shift or pressure control solenoid is the most common starting point (~38%), followed by fluid level, condition, or filter.
