66RFE Tcc Solenoid 2010-2018, remanufactured and ready to install. Fits the 66RFE. Ships fast from the USA.
The title on this listing says TCC solenoid, but what you get is a complete remanufactured valve body. It is a heavy-duty 5 check ball unit, part number CR-2762BHD, for 2010-2018 66RFE and 68RFE transmissions. It is the right part for a Ram 2500 or 3500 with the 6.7L Cummins and 68RFE, or a gas HEMI 3/4-ton or 1-ton with the 66RFE, that has converter lockup complaints, burned overdrive clutches, P0871 pressure switch codes or harsh shifts traced to worn valve body bores. The solenoid block is not included; you move your own over, or fit a new one.
On these years there is no stand-alone TCC solenoid. The low/reverse solenoid in the pack does double duty. A spool called the solenoid switch valve, which sits in the valve body, sends that solenoid's oil to the low/reverse clutch in first and reverse. In the higher gears it sends the oil to the converter clutch. GEARS Magazine traced a 68RFE P0740 converter code to exactly this shared circuit. Sonnax names the switch valve as one of the three control parts in this family, with the solenoid pack and the pressure switches. When its bore wears, the valve and its plugs stick. The result can be lockup trouble, cross-leaks that burn the overdrive clutch and set P0871, or bind-up. That is why a lockup problem on a 2010-2018 truck often ends at the valve body, not a solenoid.
Read the codes and freeze-frame data, and check that the fluid is full and not burnt. Then test the solenoid pack coils. If they read in spec and the faults keep coming back, the valve body bores are the next suspect. Our 68RFE valve body testing guide covers pressure switch checks and vacuum testing the switch valve bore. The P0871 guide explains how a switch valve cross-leak sets that code.
This unit is listed for 2010-2018 66RFE and 68RFE transmissions with the 5 check ball layout. Earlier units in our catalog are listed as 7-ball, and a 7-ball body does not swap onto a 5-ball case. Transmission Digest also notes that pack connectors changed from white to gray around 2010 and to blue in 2019. The 2019 and later units add separate TCC and reverse solenoids, so this valve body is not for 2019-up trucks. Count the check balls in your old valve body and note the connector color, or send us your year and VIN and we will confirm it. Browse the 68RFE parts collection or the 66RFE collection for matching parts.
Transfer your solenoid pack, or use a new gray-connector 2010-2018 solenoid block if yours tests weak. Torque the pack-to-valve-body bolts to the 53 in-lb in the Transend sheet. Put in a new filter and fill with ATF+4; the 68RFE service kit includes fluid and filters. Then run the quick learn with a scan tool and drive through 10-15 complete shift cycles so the controller can re-learn clutch volumes. Check the level with the fluid hot. If the old valve body burned the overdrive clutch, a valve body alone will not fix the slip.

No. It is a complete remanufactured 5-ball heavy-duty valve body for 2010-2018 66RFE and 68RFE units. On these years converter lockup runs through the low/reverse solenoid and the solenoid switch valve in the valve body, which is why lockup faults often lead to this part.
No. The solenoid block is not included. Transfer your known-good pack or install a new 2010-2018 gray-connector pack, torqued to 53 in-lb.
No. The 2019 and later 68RFE uses a blue connector pack with separate TCC and reverse solenoids and a different valve body. This unit is for 2010-2018 only.
Yes, the listing covers both for 2010-2018 with the 5 check ball layout. Confirm the check ball count and connector on your old unit, or send us your VIN.
Yes. Run the quick learn with a scan tool, then drive through 10-15 full shift cycles. Use ATF+4 and set the level with the fluid hot.
