48RE Solenoid Kit 2000, new and ready to install. Fits the 48RE. Ships fast from the USA.
A 2000 Dodge Ram that starts in second, holds a gear too long, will not go into overdrive, or sets a governor pressure or converter clutch code is usually asking for the parts in this kit. It is listed under 48RE, but the 48RE had not been built yet in 2000. On a 2000 Ram the transmission is a 46RE behind the gas V8s or a 47RE behind the Cummins and the V10, and those units share the same electronic governor and solenoid layout the 48RE later carried over. What is in the photo: the dual overdrive/converter clutch solenoid assembly with its harness and round case connector, a boxed BorgWarner governor pressure solenoid, a governor pressure sensor with a rectangular plastic connector, and the governor body gasket. There is no filter or pan gasket in this kit.
These transmissions shift first through third hydraulically. The shift valves move when governor pressure overpowers throttle pressure, and on the RE units the governor pressure is made by a solenoid instead of spinning weights. Chrysler describes it as a duty-cycle solenoid fed with line pressure: about 1 amp gives zero governor pressure and zero amps gives the maximum. The governor pressure sensor reads the result and reports back to the PCM, which closes the loop. The 3-4 shift and converter lockup are separate jobs handled by the two coils in the overdrive/converter solenoid block bolted to the valve body.
Read codes with the engine running, because the transmission control relay that powers these solenoids only switches on once the engine is running. A no-power fault there will look like a dead solenoid. Compare desired and actual governor pressure on a scan tool and, if you can, put a 0-100 psi gauge on the governor port. If actual pressure will not follow desired, the solenoid or its feed is the suspect; if the gauge is right but the PCM reading is wrong, look at the sensor and its wiring. Our governor pressure solenoid guide walks the full test, and the overdrive and TCC solenoid testing guide covers the two coils on the valve body.
This listing is for 2000 model year Ram trucks. The year matters because of the sensor. Sonnax's valve body identification splits the RE family at 2000: 1999 and earlier sensors use an oval connector, while 2000 and later use a rectangular plastic one, which is what this kit shows. If your truck still has the early oval plug, look at our 1994-1999 solenoid kit instead. Before ordering, compare the sensor plug and the round case connector on your harness with the photo, or send us the year and VIN and we will check it. The rest of the RE line is on our 48RE collection page.
Drain the pan and remove the filter, then unplug the governor sensor and solenoid. The governor body comes off the transfer plate with its retainer plate; the sensor slides out once the M-shaped clip is picked free, and the solenoid pulls straight out of its bore. The overdrive/converter solenoid block is held to the valve body by screws, and its case connector is retained by a small shoulder bolt at the 3-4 accumulator housing, so keep that bolt. Use new O-rings, push the new solenoid in until it snaps, lay the new gasket, and torque the governor body screws to 35 in-lb. Chrysler then calls for the line pressure and throttle pressure adjustments before the pan goes back on. Refill with ATF+4. If the old harness is heat-cracked or the valve body itself is worn, an internal solenoid harness or a remanufactured valve body is the better fix.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
That is the point of it. The 48RE came later; a 2000 Ram has a 46RE or 47RE, and both use this electronic governor and dual OD/converter solenoid design. Match the rectangular sensor plug and the harness case connector to your truck, or send the VIN.
Per the photo: the overdrive/converter clutch solenoid assembly with harness and case connector, a governor pressure solenoid, a governor pressure sensor and the governor body gasket. A filter and pan gasket are not part of this kit, so buy them separately if you plan to drop the pan.
GEARS documented brand-new aftermarket governor solenoids that would not let governor pressure rise to line pressure, so the 2-3 only happened when the driver lifted. An OE solenoid fixed it. Check actual governor pressure against line pressure with a gauge.
Mopar ATF+4. It superseded the ATF+3 named in older Ram manuals. Check the level hot, idling, in Neutral.
Chrysler's procedure calls for the line pressure and throttle pressure adjustments after governor service, then clear codes and road test while watching desired versus actual governor pressure.
Yes if testing points only to the sensor, but a sensor code can also come from wiring, a shared ground, or a solenoid that is not making pressure. The kit replaces all three electrical pieces at once.
