P2723 on Buick vehicles indicates pressure control solenoid "e" performance/stuck off. Au7o has documented this code across 1 Buick model — most commonly on Enclave. P2723 is a generic powertrain code set when the transmission control module detects that pressure control solenoid "E" is stuck off or not responding as commanded. In an automatic transmission, electronically controlled pressure solenoids regulate hydraulic fluid pressure to the clutches and bands that engage each gear; this code appears on transmissions with five or more such solenoids (A through E), and the exact clutch the "E" solenoid controls varies by transmission design. When the solenoid sticks off, the computer typically defaults to maximum line pressure or limp mode, so you may feel harsh or delayed shifts, slipping, the transmission holding one gear, or even stalling when coming to a stop. Continuing to drive with this fault puts extra wear on internal transmission components and can turn a solenoid or fluid problem into a full transmission rebuild. Typical repair costs on Buick range from $2,500 to $4,500, depending on the specific model and root cause.

Common Causes of P2723

  • •Failed or mechanically sticking pressure control solenoid E
  • •Low, dirty, or contaminated transmission fluid (often with a clogged filter)
  • •Damaged wiring or corroded connector in the solenoid E circuit (open or short)
  • •Valve body fault or debris-blocked hydraulic passages
  • •Weak or failing transmission pump causing low line pressure
  • •Internal transmission mechanical damage (clutch debris, metal shavings)
  • •Faulty TCM/PCM (rare)

Buick Enclave(1 issue)

  • 6T70/6T75 Transmission Wave Plate Failure2008-2012

    First-generation Enclaves (2008-2017) use the 6T70/6T75 6-speed automatic, whose stamped-steel 35R wave plate can crack at the teeth after enough shift cycles. When it fractures, the transmission abruptly loses 3rd, 5th, and reverse gears, and debris can damage the valve body, drums, and torque converter. Failure typically occurs in higher-mileage 2008-2012 builds.

Frequently Asked Questions

What does P2723 mean on Buick?▼

P2723 stands for "Pressure Control Solenoid "E" Performance/Stuck Off." P2723 is a generic powertrain code set when the transmission control module detects that pressure control solenoid "E" is stuck off or not responding as commanded. In an automatic transmission, electronically controlled pressure solenoids regulate hydraulic fluid pressure to the clutches and bands that engage each gear; this code appears on transmissions with five or more such solenoids (A through E), and the exact clutch the "E" solenoid controls varies by transmission design. When the solenoid sticks off, the computer typically defaults to maximum line pressure or limp mode, so you may feel harsh or delayed shifts, slipping, the transmission holding one gear, or even stalling when coming to a stop. Continuing to drive with this fault puts extra wear on internal transmission components and can turn a solenoid or fluid problem into a full transmission rebuild. On Buick specifically, this code is documented across 1 model.
