The Ultimate 68RFE Valve Body Upgrade: Billet Precision & Rigidity
The factory 68RFE channel plate is prone to flexing under load, which causes cross-leaks and blows out gaskets, leading to transmission failure. The Solution: Billet Precision & Rigidity. Our Billet Channel Plate is the permanent fix for channel plate flexing. CNC-machined from a solid slab of 6061 Billet Aluminum, it is nearly 3x thicker than stock and machined to .0003" flatness. This rigidity forces the accumulator pistons and valves to seal correctly, allowing you to run higher line pressure without blowing out gaskets or seals from the casting distorting. This is the ultimate valve body for high-horsepower builds, heavy towing, and aggressive tuning.
Fixes Common Failures: Bonded Separator Plate, Steel Switch Valve & Billet Pistons
In addition to the massive upgrade of the Billet Channel Plate, this valve body addresses every other weak point in the 68RFE hydraulic system. We replace the weak factory plastic pistons with Billet 3-Ring Accumulator Pistons that won't crack and cause clutch burn-up. We install an upgraded steel switch valve to fix the common bore wear issues found on OEM valve bodies that trigger P0871 codes and catastrophic Overdrive clutch failure. Finally, a bonded separator plate is installed to further eliminate cross-leaks and ensure fluid pressure is routed exactly where it needs to go.
Recommended Add-Ons: Protect Your Investment
You are upgrading your valve body to handle higher pressure and prevent failure, but two major weak points remain in the 68RFE system: Heat and Case Flex. We recommend adding these components to ensure your new valve body performs at its peak.
1. PPE Cast Aluminum Deep Transmission Pan (Raw Finish)
The factory stamped-steel pan is flimsy. Under high torque and line pressure, the 68RFE case can actually distort and flex, causing internal cross-leaks that undermine even the best valve body. The PPE Cast Aluminum Pan is thick and rigid, acting as a girdle that strengthens the transmission case to prevent this flex. Additionally, it holds extra fluid and uses deep external cooling fins to keep your transmission running significantly cooler. The cast pan also includes a drain plug making future oil changes a breeze.

2. PPE Thermal Bypass Valve (Fits 2013-2018 Models)
The stock cooling system uses a thermostatic valve that restricts fluid flow to the cooler until the transmission gets hot. In performance or towing scenarios, this delay can spike temperatures and damage clutches. This PPE Bypass Valve removes that restriction, forcing 100% of the fluid through the cooler from the moment you start the truck.
(Note: Fits 2013-2018 only. Not compatible with 2007.5-2012).

68RFE Valve Body Specifications:
- Vehicle Fitment: 2007.5-2018 Ram 2500 & 3500 with 68RFE Transmission
- Channel Plate: Tier One Billet 6061 Aluminum
- Accumulator Pistons: Billet 3 Ring
- Accumulator Plate: Extra thick with more bolts
- Separator Plate: Bonded Separator Plate
- Switch Valve: Upgraded steel valve assembly
- Solenoids: OEM
- Flat Sanding: Yes
- Dyno Tested: Yes
Tuning Notes:
- Max line pressure during road test: High pressure VB needs to be at 225psi at 25-30% throttle angle (Stock VBs are 160psi).
- Line pressure in reverse should reach 250psi.
- Use of factory lock strategy must be used or transmission damage will occur.
- UD Pulse: 2019 and up should have UD pulse turned off (Please verify on 2017 and 2018 Rams as some are equipped with this option).
- Every 68RFE must have a relearn completed or failure will result.
For 2007.5-2018 Ram 2500 or 3500 with 68RFE only: this valve body will only fit 2007.5-2018 Ram 2500 or 3500 with a 68RFE transmission only. A
2019-2024 Ram 2500 & 3500 Billet High-Pressure 68RFE Valve Body is also available. Neither of these valve bodies will fit Ram 3500s with AS69RC transmissions.
Relearn required: installation of this valve body will require a transmission relearn for proper operation.
Requires core charge: this valve body requires an additional $500 core charge, which will be refunded in whole or in part once Tier One receives your stock valve body, inspects it and finds it in acceptable condition. The core charge can be waived if you send in or drop-off your stock valve body ahead of time.
