P0796 on Chevrolet
Pressure Control Solenoid 'C' Performance or Stuck Off
P0796 on Chevrolet vehicles indicates pressure control solenoid 'c' performance or stuck off. Au7o has documented this code across 1 Chevrolet model — most commonly on Traverse. This generic transmission code means the TCM/PCM detected that pressure control solenoid 'C' is not regulating hydraulic pressure as expected, or appears stuck in the off position. These solenoids control the line pressure that applies the transmission's clutch packs to achieve the correct gear ratios, so a performance fault here disrupts shift quality. Symptoms can include harsh or delayed shifts, slipping, or limp mode, and continued driving can accelerate transmission wear. Typical repair costs on Chevrolet range from $150 to $2,500, depending on the specific model and root cause.
Common Causes of P0796
- •Faulty pressure control solenoid C
- •Low, dirty, or degraded transmission fluid
- •Blocked or restricted valve body fluid passages
- •Damaged wiring or connector to the solenoid
- •Worn valve body or stuck valve
- •Internal transmission mechanical wear
- •Faulty TCM/PCM (rare)
P0796 on Chevrolet by Model
Chevrolet Traverse(1 issue)
- 9-Speed Automatic Transmission Shudder (9T65)2018-2025
The second-generation Traverse (2018+) uses the GM 9T65 9-speed automatic transmission that suffers from a shudder during light acceleration in the 25-50 mph range. The torque converter clutch chatters during lockup, producing a vibration that feels like driving on a rumble strip. The 9-speed also exhibits harsh downshifts, hunting between gears on hills, and delayed engagement from Park. GM has released multiple TCM software updates to address the shifting behavior, but the underlying torque converter weakness remains.

What does P0796 mean on Chevrolet?▼
P0796 stands for "Pressure Control Solenoid 'C' Performance or Stuck Off." This generic transmission code means the TCM/PCM detected that pressure control solenoid 'C' is not regulating hydraulic pressure as expected, or appears stuck in the off position. These solenoids control the line pressure that applies the transmission's clutch packs to achieve the correct gear ratios, so a performance fault here disrupts shift quality. Symptoms can include harsh or delayed shifts, slipping, or limp mode, and continued driving can accelerate transmission wear. On Chevrolet specifically, this code is documented across 1 model.
