65RFE Overhaul Kit 2019, new and ready to install. Fits the 65RFE. Ships fast from the USA.
Shopping for a 65RFE overhaul kit for a 2019 truck usually means the transmission is shifting soft, flaring between gears, or burning clutches again after earlier work. Before you order, know exactly what this listing is: it is not a gasket and seal overhaul set. It is a new billet valve body rebuild kit, part number CR-2769-RKM, made for the 5-ball RFE valve body used from 2019 on. The same kit is listed for the 65RFE, 66RFE and 68RFE names because those six-speed RFE units share the valve body design it fits. If what you need is clutches and seals, see the gasket and seal kits linked below instead.
The channel plate and separator plate are designed as a pair and must be installed together. You reuse your own valve body castings, spool valves and solenoid pack.
An RFE transmission has no governor or throttle cable. The transmission computer commands each shift with solenoids, and the valve body turns those signals into apply pressure for each clutch. The solenoid switch valve is a busy part of that system: it moves back and forth on the upshifts, and over time its bore wears and leaks, which starves the clutch it feeds. Sonnax notes the switch valve itself carried over unchanged into 2019, so the same wear pattern applies to the newer units. The stamped steel channel plate and plain separator plate that came from the factory can also flex and leak under high line pressure, which is what the billet plates and blocked separator are meant to stop.
Start with the easy checks: correct ATF+4 fluid level with the fluid hot, a code scan, and any open recalls or software updates for the truck. Then compare commanded and actual line pressure on a scan tool and watch how the clutch volume indexes change. Sonnax recommends a vacuum test on the switch valve and bore plug to prove wear before parts are bought. Our RFE valve body problems and testing guide walks through those tests, and the shift solenoid symptoms guide helps rule out the solenoid pack first.
This kit fits 5-ball RFE valve bodies from 2019 and later. Sonnax documents the 2019 redesign on the 68RFE: a lower valve body section was added to the channel plate to hold a new TCC solenoid and a Reverse accumulator, and the solenoid pack connector changed from gray to blue. If your 65RFE-coded unit does not have that lower section and blue connector, this kit is the wrong part. Check the valve body before ordering, or send us your year and VIN and we will confirm it. Other parts for this family are on our RFE transmission parts page.
Disassemble the valve body on a clean bench, one section at a time, and lay the parts out in order. Install the drop-in switch valve and plugs in the original bore; no reaming is needed. Fit the new accumulator pistons with their seals lubricated in ATF+4, install the separator plate and gaskets with the billet channel plate, and torque the heavy-duty bolts evenly in a cross pattern to the service manual value. If the clutches are already burnt, do the full job with a seal and clutch set such as the 2019-2022 68RFE overhaul kit. If the case or hard parts are too far gone, a complete 2019-24 68RFE replacement transmission may cost less in the end. Refill with ATF+4, set the level hot, and run the quick learn with a scan tool before road testing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Despite the listing title, this is a billet valve body rebuild kit, part number CR-2769-RKM. It contains valve body plates, pistons, a switch valve, plugs and bolts, not transmission clutches or case seals.
Only if the valve body is the 2019-and-later 5-ball design with the lower valve body section on the channel plate and the blue solenoid pack connector. Earlier valve bodies need a different kit. Send us your year and VIN if you are unsure.
No. You reuse your own solenoid pack, castings and spool valves. If a solenoid has failed, replace it separately.
No. The solenoid switch valve and plugs are a drop-in design that installs in the original bore without reaming.
Use ATF+4 only, check the level with the fluid at full operating temperature, and run the quick learn procedure with a scan tool after installation.
