65RFE Solenoid Kit 1999-2018, new and ready to install. Fits the 65RFE. Ships fast from the USA.
A 65RFE that locks itself in one gear, slips on a single shift, or keeps setting solenoid and pressure switch codes is usually telling you the solenoid pack, or the wiring to it, can no longer do what the transmission computer asks. This is a new 65RFE solenoid kit for the pre-2019 six-speed RFE design used in Ram and other Chrysler-built trucks and SUVs. The product photo shows a light-colored connector pack with its green connector seal, a primary sump filter, a spin-on cooler return filter and a molded pan gasket. That is everything you would normally replace once the pan is down, in one box.
The 65RFE grew out of the four-speed 45RFE and 545RFE and keeps the same basic pack and valve body layout, but it uses the clutches differently to get six forward gears. According to the Sonnax apply chart, first is 3.23, second 1.83, third 1.41, fourth 1.00, fifth 0.81 and sixth 0.62, with reverse at 4.44. Each of those ratios comes from a pair of clutches applied by the pack: underdrive, overdrive, second, fourth and low/reverse, with the multi-select solenoid and the line pressure solenoid working alongside. Because the six-speed calibration asks for different clutch combinations than the four-speed did, a pack problem on a 65RFE often shows up as a fault in fifth or sixth that a four-speed owner never sees.
Not every RFE complaint is the pack. Sonnax points out two common ones that are not even valve body related: a neutral feel just after launch in Drive usually comes from a failed low roller clutch or low sprag, and stalling or converter clutch engagement trouble traces back to the torque converter limit valve in the pump. Before ordering, measure each solenoid from pin 10 at the pack connector (about 1.3 ohms for clutch solenoids, about 4.3 ohms for line pressure), inspect the case connector, and compare commanded and actual line pressure on a scan tool. Our RFE shift solenoid testing guide and the RFE pump failure guide cover both paths and apply to the 65RFE because the hardware is shared.
The listing range of 1999-2018 is the span Sonnax gives for this pack and valve body family, from the first 45RFE through the last pre-2019 six-speed. The 65RFE itself is a later member of that family, so read the range as the pack design, not as a 1999 65RFE. Transmission Digest dates the white connector from 2004, a gray connector from about 2010 when the overdrive solenoid was dropped, and a blue connector from 2019. The pack pictured has the light white-style connector, and Sonnax calls the white connector pack the universal choice for this valve body family. It is not for 2019-up blue-connector units. Compare it with our other 65RFE solenoid kit, see more parts on the six-speed RFE parts page, or send us your year and VIN to confirm.

Sonnax lists one pack and valve body bolt-up for the whole 1999-2018 RFE family. What changes between the four-speed and six-speed units is the calibration and the accumulator springs, plus the connector generation, so match the connector color on your old pack.
No. 2019-up units use a blue-connector pack with a separate converter clutch solenoid and a different gasket.
Usually not. Sonnax ties a neutral condition after launch in Drive to a low roller clutch or low sprag failure, which a solenoid pack will not fix.
Fill with ATF+4, check the level hot, then run the quick learn with a scan tool and drive 10 to 15 upshift and downshift cycles.
