P282C is intended for an intermittent problem at solenoid K. No manufacturer publishes a description; CARB 13 CCR 1968.2 requires monitoring of transmission actuators without prescribing a separate code for sporadic faults. The only documented K application, GM's selector pilot valve in the 2023 Corvette dual-clutch box, confirms its circuit faults after a 100 ms debounce, so a contact breaking for a shorter time can escape the memory while still upsetting the choice of shift rod. On any car with this code, heat and vibration are the prime suspects: check connector locking, pin tension and the internal leads of the mechatronic unit while watching live data, and save the freeze frame before clearing anything.

Likely causes

Weak pin tension or unlatched connector
Heat-related dropout of the coil or internal lead
Harness chafing under vibration

Symptoms

  • Occasional failed gear preselection
  • Warning that disappears after restart

Repair estimate
