68RFE Tcc Solenoid 2019, new and ready to install. Fits the 68RFE. Ships fast from the USA.
This is the stand-alone torque converter clutch solenoid for the redesigned 2019 68RFE, the six-speed behind the standard-output 6.7L Cummins in the Ram 2500 and 3500 Heavy Duty. If your 2019 truck has a converter shudder at cruise, transmission temperature that keeps climbing on the highway, or a TCC slip code, this single cartridge solenoid is the part that controls lockup. It is a much smaller and less expensive repair than the solenoid pack on earlier trucks, because on the 2019 design the TCC function was moved out of the pack.
For 2019, Ram fitted the high-output Cummins with the Aisin AS69RC and gave the standard-output engine what its press materials call a significantly upgraded 68RFE. Part of that upgrade was in the valve body. On every earlier RFE, the low/reverse solenoid in the pack did double duty and also applied the converter clutch. Transmission Digest describes the 2019 change: a small housing on the lower channel plate now holds a separate TCC solenoid, and the low/reverse solenoid only applies the L/R clutch in Park, Neutral and first. Sonnax adds that this solenoid mounts to the opposite side of the valve body from the pack. With its own solenoid, the controller can modulate converter lockup without sharing a circuit with a shifting clutch, and that is why a lockup complaint on a 2019 truck can now come down to this one part.
Lockup codes on the 68RFE are not always electrical. In a GEARS Magazine case on a 2016 truck, P0740 traced back to a worn solenoid switch valve and a worn converter accumulator piston, with TCC release pressure at 20 psi where it should be 5 psi or less. Log TCC slip, commanded lockup and transmission temperature with a scan tool on a highway drive, and check fluid level hot. A solenoid that is commanded on with slip that never drops points at the solenoid or its hydraulic circuit; contamination or a valve body that will not hold vacuum points elsewhere. Our 68RFE Ram 3500 Cummins shift problems guide and 68RFE valve body testing guide cover the checks.
The listing is for the 2019 68RFE. That means a 2019 Ram 2500 or 3500 with the standard-output 6.7L Cummins and the 68RFE, not the high-output engine, which uses the Aisin. Quick check: on the 2019-on design the pass-through connector on the solenoid pack is blue. A 2007-2018 68RFE with a white or gray connector has no separate TCC solenoid at all, so this part does not apply to those trucks. The 2019 layout continued on later 68RFE units, but if your truck is 2020 or newer, send us the year and VIN so we can confirm the solenoid matches before it ships. Every other part we stock for this transmission is on the 68RFE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Before 2019, the 68RFE had no separate TCC solenoid; the low/reverse solenoid inside the solenoid pack also controlled lockup. On those trucks the pack is the TCC repair.
Look at the solenoid pack pass-through connector. The 2019-on design uses a blue connector and a separate TCC solenoid at the valve body. White or gray connectors are the earlier design.
No. The 2019 high-output Cummins uses the Aisin AS69RC. This solenoid is for the 68RFE behind the standard-output engine.
Yes, on the 2019 design they are separate parts. Only replace the pack as well if testing shows a pack fault or pressure switch codes.
Refill with ATF+4, check the level hot, clear codes, and run the quick learn with a scan tool before road testing lockup.
