65RFE Governor Pressure Solenoid 2009-2018, remanufactured and ready to install. Fits the 65RFE. Ships fast from the USA.
A lot of Ram 1500, Durango and Grand Cherokee owners search for a 65RFE governor pressure solenoid when the truck drops into second gear limp mode or starts throwing solenoid codes. The name comes from the old four-speed Dodge units, which really did use a governor pressure solenoid. The 65RFE never had one. Everything that used to be done by the governor and the throttle valve is handled electronically by the solenoid block on top of the valve body. That is what this listing is: a Sonnax remanufactured RFE solenoid block, part number 44836B, with the gray pass-through connector used on the 2010-and-later pack generation.
The 65RFE is the six-speed version of Chrysler's RFE family, and like the 545RFE it shares a case and a valve body layout with, it has no hydraulic governor at all. The transmission controller decides which clutches to apply and energizes the matching solenoids on this block. The same housing carries the line pressure variable force solenoid that sets overall pressure, plus the pressure switches that report back when each clutch circuit actually filled. Sonnax notes that when Chrysler moved to the gray pack it dropped one of the six solenoids and two checkballs, and let the multi-select solenoid cover the overdrive job. So the gray block is a five-solenoid part, and it only works with a valve body built for it.
A remanufactured block from Sonnax is disassembled, cleaned, rebuilt with new seals and springs, and bench tested, according to the listing. It is listed as a direct replacement that does not need a separate selector plate purchased with it.
Do the cheap checks first. Confirm the fluid level hot and look at its condition, then check battery voltage and the transmission control relay feed, because every solenoid on the block shares one supply. With a scan tool, compare desired and actual line pressure. Sonnax documents that an open pressure control circuit drives actual pressure to maximum while the duty cycle stops responding, which is a block or wiring fault rather than a pump problem. Pressure switch codes are trickier: worn valve body bores can mimic a failed block. Our RFE shift solenoid testing guide covers resistance and scan checks that apply to the whole family, and the 545RFE pressure testing guide shows how to put a gauge on this case design.
The block is listed for 2009-2018 65RFE, 66RFE, 545RFE and 68RFE transmissions with the gray connector. GEARS Magazine places the 65RFE in the Ram 1500, Durango and Grand Cherokee with the 4.7L and 5.7L engines. The year range needs care: Sonnax gives both 2009 and 2010 for the gray-pack changeover, so a 2009 vehicle can have either pack. Drop the pan and look at the connector on your current block. Gray means this part fits. White means you have the earlier six-solenoid design, and Sonnax is clear that a gray block cannot back-service it. A 2019-up blue-connector pack is also a different part. If you are not sure, send us your year and VIN. More parts for this family are on our 545RFE and 65RFE parts page and the 68RFE parts page.
If your scan data pointed at low pressure rather than the block, the 65RFE pump belongs in the same job. A truck that tows or runs hot should also get an auxiliary transmission cooler, since heat is what cooks the solenoid coils and seals in the first place.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The governor pressure solenoid was used on the older four-speed RE transmissions. The 65RFE controls shifts and line pressure through the solenoid block on the valve body, which is what this listing is.
Only if your current block has the gray connector. 2009 sits on the changeover between the white and gray packs, and a gray block cannot replace a white one. Pull the pan and check, or send us your year and VIN.
It is listed as a Sonnax remanufactured solenoid block, part number 44836B, disassembled, cleaned, rebuilt with new seals and springs, and tested.
ATF+4 only. Set the final level with the fluid hot and the engine running.
Yes. Clear the codes and run the quick learn so the controller relearns clutch fill times with the new solenoids, then expect shifts to refine over a few drives.
