Shift solenoid G only exists on transmissions with seven or more solenoids. Ford's 10R80 and 8F35 use solenoids A–F, GM's 9- and 10-speeds report clutch pressure valve codes, the Allison 1000 uses three; the only documented user of the G block is Hyundai/Genesis' 8-speed, which assigns P075A and P075D to its on/off solenoids. P075B means solenoid G is commanded on but valve or clutch do not follow, detected like P0751 by ratio, slip or pressure switch. No manufacturer document available to us uses this code; Ford's 10-speed bulletins end at solenoid F. The description follows the scheme for solenoids A and B.

Likely causes

Shift spool in the valve body sticking (dirt, debris)
Internal leak or clutch fault in the circuit
Solenoid mechanically sluggish or screen clogged
Fluid level or quality wrong

Symptoms

  • Gears missing or skipped
  • Pulling away in the wrong gear, weak acceleration
  • Limp mode or gear lock-out
  • Check engine light
