P2807 is the umbrella code for pressure control solenoid G; the fault type follows in the extra byte. Which hydraulic function G controls is set by each maker. Toyota uses it on its eight-speed automatics: bulletin T-SB-0160-18 lists P28077F (actuator stuck off) on 2017-2018 Highlander and Sienna together with other solenoid codes, whine, harsh shifts and reduced power, and supplies a remanufactured transaxle. T-SB-0076-24 for the 2024 Tacoma names P280771 (actuator stuck) and replaces gearbox and converter. GM's 2016 eight-speed table assigns G to the converter clutch. Specific sibling codes are P2808 to P2815. Debris in the valve body is the usual root cause, so fluid analysis comes first.

Likely causes

Debris or wear particles jamming the valve

Internal transmission damage producing particles

Solenoid G worn or electrically weak

Symptoms

MIL on with harsh or delayed shifts
Whine noise from the transmission
Reduced power or limp mode
