48RE Clutch Module 2000, remanufactured and ready to install. Fits the 48RE. Ships fast from the USA.
This listing is filed as a 48RE clutch module for 2000, but the part in the photo is a complete remanufactured valve body, assembled with its electrical components and wiring harness, not a set of clutch plates. It is aimed at the owner of a 2000 Dodge Ram whose automatic has started to flare between gears, slip under load, shift late or erratically, or lose converter lockup, and who wants to bolt in a rebuilt valve body rather than tear down and clean every bore of a worn one.
Sonnax states plainly that the 48RE was introduced in 2003. A truck built in 2000 therefore left the factory with one of the earlier RE-family units, the 46RE or 47RE, even though parts for all three are often grouped under the 48RE name. That matters for a valve body more than for almost any other part. Sonnax reports that shops who install a 46/47RE valve body in a 48RE see it work at first and then come back with a failed converter clutch or overdrive clutch, because the 48RE pressure regulator circuit and its converter clutch solenoid feed are different. So treat this as a valve body for a 2000-era transmission. If your truck is a 2003 or newer with a true 48RE, use our 48RE valve body for 2003-08 instead.
The RE units are hydraulically shifted 4-speeds with electronic control layered on top. The valve body holds the manual valve, the pressure regulator, the throttle valve, the 1-2 and 2-3 shift valves and the governor plugs, and from 1996 on it also carries the electronic governor pressure solenoid and sensor that replaced the old mechanical governor. Line pressure, shift timing and shift feel all come out of this one casting. When its bores wear, oil leaks past the valves, pressure drops or wanders, and the clutches and bands start to slip even though the hard parts were fine when they went in.
Sonnax ties the shift-timing set of symptoms to oil leaking past the governor plugs in worn bores, and notes that the solenoid and sensor cannot correct a leak that large.
Scan for transmission codes first and rule out the throttle position input and the governor pressure solenoid, since a bad electrical part can mimic a worn valve body. Check fluid level and condition with the engine idling and the fluid hot. A line pressure test that comes up low in one range but not another points to the valve body or a leaking clutch circuit. Our RE-family failure point guide walks through the valve body wear spots, and our solenoid testing guide covers the electrical checks.
The listing places this unit at the 2000 model year. Within the RE family the valve body changed between gas and diesel calibrations and across the electronic governor years, so compare it to the one you remove: governor solenoid and sensor location, harness connector, throttle and manual lever, and any casting numbers. If you are unsure, send us your year, engine and VIN before ordering. You can browse every RE part we carry on the 48RE collection page, including the 1997-2002 valve body for nearby years.
If the old fluid was burnt, the clutches already took damage and should be inspected. A fresh governor pressure solenoid is worth fitting at the same time if yours is original.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows a complete remanufactured valve body with its electrical parts and harness attached. It does not contain friction or steel plates. If you need clutch plates, look at our other RE clutch pack listings.
We do not recommend it. Sonnax reports that 46/47RE valve bodies installed in 48RE transmissions tend to return with a failed converter clutch or overdrive clutch because the 48RE pressure regulator and converter clutch feed are different. Use a valve body built for the 48RE.
Chrysler specifies ATF+4 for the RE transmissions. Check the level with the engine idling, the fluid hot and the selector in Neutral.
Yes. Set the throttle valve linkage to the service manual procedure, and clear any stored codes. A misadjusted throttle cable causes late or soft shifts and low line pressure even with a good valve body.
Compare the governor solenoid and sensor, harness connector and levers with the valve body you remove, or send us your year, engine and VIN before ordering and we will check it.
