P2715 on Chevrolet by model: symptoms, diagnosis and fix
Silverados with the Hydra-Matic 8L90 (and 8L45) 8-speed automatic are widely reported to hesitate, then shudder, jerk, clunk or 'hard shift' when changing gears — some owners describe a shift so violent it feels like being rear-ended, plus a torque-converter-clutch shudder that feels like driving over rumble strips. The root cause is internal friction/hydraulic issues and torque-converter-clutch micro-slip, often worsened by the original transmission fluid breaking down, sending metal shavings through the unit. GM issued 13+ TSBs and a fluid change (to Mobil 1 Synthetic LV ATF HP / DEXRON-ULV) as the primary remedy, and the defect was the subject of a class action (Speerly v. GM) covering 2015-2019 Silverado and other GM models, though the Sixth Circuit en banc vacated its class certification in June 2025. Very high search and complaint volume.
Common Symptoms
- Shudder / vibration like driving over rumble strips
- Harsh or violent hard shifts (clunk/bang)
- Hesitation then surge on acceleration
- Slipping or flaring between gears
- Jerking at low speed / when slowing
How to Fix
First-line fix per GM TSB is a full transmission fluid flush/exchange to the updated low-viscosity fluid (Mobil 1 Synthetic LV ATF HP), which resolves many shudder cases. Persistent shudder or hard shifts may require torque-converter replacement, valve-body service, or transmission overhaul. Adding an auxiliary transmission cooler helps prevent recurrence. Document repairs — they support warranty or lemon-law claims.

Frequently asked questions
What does P2715 mean on a Chevrolet?
P2715 stands for "Pressure Control Solenoid "D" Stuck On." A generic OBD-II powertrain code (part of the P2714/P2715/P2716 set covering solenoid "D" performance, stuck-on, and electrical faults). The PCM/TCM commanded pressure control solenoid "D" off, but the resulting line pressure stayed high — the solenoid is behaving as if stuck applied. Pressure control solenoids regulate the hydraulic pressure that applies the clutch packs, so a stuck one causes harsh, delayed, or wrong-gear shifting. The transmission often drops into limp mode to protect itself. On Chevrolet it is documented across 1 model: Silverado.
What are the most common causes of P2715?
The most common causes of P2715 are: Failed or mechanically stuck pressure control solenoid "D" (solenoid body/pack), Contaminated or degraded transmission fluid, or an incorrect fluid level, Debris or varnish in the valve body bore preventing the valve from returning, Damaged wiring, connector, or internal transmission harness to the solenoid, Internal transmission damage (worn clutches, failed pump) producing abnormal pressure, Failed TCM/PCM solenoid driver circuit (rare — verify everything else first). The specific cause varies by vehicle.
How much does it cost to fix P2715 on a Chevrolet?
Published repair estimates on Chevrolet range from $200 to $4,000 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.
