P2810 is a collective electrical code for solenoid G: the control unit sees a fault in coil or wiring but does not split it into open, low or high. No manufacturer documents P2810 publicly. The makers that do use valve G report electrical faults more precisely. GM's 2020 table lists the open circuit as P2812 with the ten-speed line pressure valve and the eight-speed converter clutch valve as G, and Ford's 2024 summary books the even clutch cooling valve of its TR9070 dual-clutch box under P2812, P2814 and P2815. CARB 13 CCR 1968.2 requires such output circuits to be monitored. If the code does appear, measure the coil resistance and check the connector and the supply from the module.

Likely causes

Coil of solenoid G open or shorted internally
Damaged internal harness or lead frame
Corroded or loose transmission connector
Faulty output stage in the control module

Symptoms

  • MIL on and harsh shifts
  • Transmission in default pressure or limp mode
