P0868 on RAM
Transmission Fluid Pressure Low
P0868 on RAM vehicles indicates transmission fluid pressure low. Au7o has documented this code across 1 RAM model — most commonly on 1500. This code indicates the transmission's internal fluid pressure is reading lower than the computer expects for current operating conditions. The transmission control module uses a pressure sensor to monitor line pressure, which is what applies the clutches and bands that engage gears. When that pressure stays below the target threshold, P0868 sets. Low line pressure can cause slipping, harsh or delayed shifts, and in severe cases internal clutch damage, so it should be addressed promptly. Typical repair costs on RAM range from $300 to $3,500, depending on the specific model and root cause.
Common Causes of P0868
- •Low transmission fluid level
- •Worn or stuck-open pressure control solenoid
- •Internal leak (worn seals, gaskets, or valve body)
- •Faulty transmission fluid pressure sensor
- •Clogged transmission filter
- •Failing transmission (oil) pump
- •Worn or leaking valve body
- •Wiring or connector fault to the pressure sensor/solenoid
P0868 on RAM by Model
RAM 1500(1 issue)
- ZF 8-speed (8HP70/845RE/850RE) torque-converter shudder and harsh shifting2013-2023
RAM 1500s with the ZF-based 8-speed automatic (TorqueFlite 845RE / 850RE, 8HP70/8HP75) commonly develop torque-converter clutch shudder. It feels like a slight-to-heavy vibration or 'driving over rumble strips' at part throttle and light acceleration, typically 15-50 mph as the converter approaches lock-up. Owners frequently report it around the 70,000-80,000 mile range, often tied to degraded fluid friction-modifier and/or worn/glazed torque-converter clutch material. Severe cases drop into limp mode (locked in 3rd gear with a CEL). Harsh 1-2/2-3 upshifts are also reported and are often resolved by a TCM software reflash.

What does P0868 mean on RAM?▼
P0868 stands for "Transmission Fluid Pressure Low." This code indicates the transmission's internal fluid pressure is reading lower than the computer expects for current operating conditions. The transmission control module uses a pressure sensor to monitor line pressure, which is what applies the clutches and bands that engage gears. When that pressure stays below the target threshold, P0868 sets. Low line pressure can cause slipping, harsh or delayed shifts, and in severe cases internal clutch damage, so it should be addressed promptly. On RAM specifically, this code is documented across 1 model.
What causes P0868 on RAM vehicles?▼
Common causes on RAM: Low transmission fluid level, Worn or stuck-open pressure control solenoid, Internal leak (worn seals, gaskets, or valve body), Faulty transmission fluid pressure sensor, Clogged transmission filter. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0868 on a RAM?▼
Repair costs on RAM range from $300 to $3,500, depending on the specific model and root cause.
