P2723 on Buick by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Sudden loss of 3rd, 5th and reverse gears
- Slipping or no movement
- Harsh or no shifts
- Check engine / transmission warning light
How to Fix
Disassemble and rebuild the transmission with an updated/stronger wave plate, plus replace damaged hard parts and clean out debris; in severe cases a remanufactured unit is installed.

Frequently asked questions
What does P2723 mean on a 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 it is documented across 1 model: Enclave.
What are the most common causes of P2723?
The most common causes of P2723 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P2723 on a Buick?
Published repair estimates on Buick range from $2,500 to $4,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
