About this product

Despite the sun shell name in our store title, this listing is a remanufactured heavy-duty valve body, part number CR-2762BHD, for the 66RFE and 68RFE built 2010-2018. We wrote this page for the gas side of that family: the Ram 2500, Power Wagon and 3500 chassis cab with the 5.7L HEMI, and the 6.4L HEMI 2500. Those owners show up with shifts that bang or slide, a converter that will not stay locked on the highway, or a code that returns after a new solenoid pack. If you came for a sun shell, this is not it, but on these trucks the valve body causes far more of those complaints than the gearset does.

How the valve body runs a 66RFE

The 66RFE is Chrysler's gas-truck hybrid, built from 68RFE internals and gearset in a 545RFE case, so it shares the diesel unit's ratios and its valve body family. Nothing about the shift is mechanical. The controller pulses the solenoid pack, and the valve body routes and meters that oil to each clutch, with pressure switches reporting back. Accumulators cushion each apply so the shift lands firm but not harsh. In the 2010-2018 design, the low/reverse solenoid also feeds the converter clutch through the solenoid switch valve, so a worn bore there can show up as a lockup problem or a cross-leak into another clutch.

What this heavy-duty build changes

Gas HEMI trucks see the same towing loads as the Cummins trucks with a lot more rpm and heat in the lower gears, which is where a leaky accumulator or switch valve shows up first.

How to confirm before you buy

Check the fluid level hot and read the codes with freeze-frame data. Then test the solenoid pack, since it moves to this unit and must be good. If the pack checks out and the faults persist, the valve body is next. Our RFE valve body testing guide covers the pressure switch and air checks, and the shift solenoid guide shows how to clear the pack first. Both apply to the 66RFE because the controls are shared.

Fitment

The unit is listed for 2010-2018 66RFE and 68RFE transmissions with the 5 check ball layout. On the gas side, the 66RFE arrived for 2012, so for a HEMI truck that means 2012-2018 Ram 2500, Power Wagon and 3500 chassis cab, plus the 6.4L 2500 from 2014. Transmission Digest identifies this era by its gray solenoid connector; white-connector earlier units and blue-connector 2019-up units take different valve bodies. Count the check balls in your old unit or send us your year and VIN. For lighter duty, compare the standard-duty 5-ball valve body, and see the 66RFE collection for related parts.

66RFE Sun Shell 2010-2018: common questions

Is this a sun shell?

No. The store title is wrong. The part is a remanufactured heavy-duty valve body, part number CR-2762BHD, for 2010-2018 66RFE and 68RFE transmissions.

Does it fit my 2011 Ram 2500 with the 5.7L HEMI?

Gas heavy-duty trucks got the 66RFE starting in 2012. A 2011 gas truck has a different transmission, so send us your VIN before you order.

Is the solenoid block included?

No. You move your solenoid pack over after testing it, or buy a new gray-connector pack for 2010-2018 units.

Will it work on a 2019 or newer truck?

No. 2019-up units use a blue connector and added separate solenoids, so they take a different valve body.

Do I need a scan tool after installing it?

Yes. Run the TCM quick learn after the swap, then drive through complete shift cycles so the controller relearns the clutch fill volumes.
