P2723 on Buick
Pressure Control Solenoid "E" Performance/Stuck Off
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.
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)
P2723 on Buick by Model
Buick Enclave(1 issue)
- 3-5-Reverse Clutch Wave Plate Can Fracture (Special Coverage 14404)2008-2009
GM identifies some 2008-2009 Buick Enclave vehicles equipped with a 6T70/6T75 six-speed automatic transmission in which the 3-5-reverse clutch wave plate can crack or fracture. The documented result is loss of reverse, 3rd and 5th gears; drivers may also notice slip, flare or harsh shifts and a check-engine light.

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.
What causes P2723 on Buick vehicles?▼
Common causes on Buick: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2723 on a Buick?▼
Repair costs vary widely depending on the root cause and specific Buick model.
