47RE Governor Pressure Solenoid 2000, new and ready to install. Fits the 47RE. Ships fast from the USA.
A 2000 or later Ram 2500 or 3500 with the 47RE that suddenly starts in second, shifts at random points, or will not drop back to first as it rolls to a stop has a governor pressure problem until proven otherwise. For the 2000 model year Chrysler redesigned the governor pressure sensor, so the parts for these trucks are not the same as the 1996-1999 parts even though the job is identical. This kit is built for the later design. Inside: a heavy-duty governor pressure solenoid (Borg-Warner OE 4617210), the late governor pressure sensor (OE 56028196AD), an output speed sensor (OE 4800879), a filter (OE 52118789), a cork-and-rubber pan gasket (OE 2464324) and a governor solenoid housing block gasket (OE 4886333AA). The kit is new, sold under the USA Industries brand as kit 4015E, made in the United States and ships from New York.
Behind the Cummins or the V10, the 47RE chooses first, second and third with hydraulic shift valves. Governor pressure is the road-speed signal those valves respond to, and on these trucks it is made electronically. The computer grounds the solenoid in rapid pulses to bleed line pressure down to a target, and the late sensor reports what the pressure really is so the computer can adjust. More duty cycle means less pressure. The target is zero at a stop, rises about 1 psi per mph, and the solenoid is switched off above roughly 40 mph so pressure holds the upshifts. The output speed sensor is the other half of the system: without its road-speed signal, the computer will not command governor pressure at all.
Start with a code scan and a drive while watching desired versus actual governor pressure. Both should read zero when stopped. Put a gauge on the governor pressure tap and compare it with the scan data; if the gauge is right and the scan tool is wrong, the sensor is bad; if pressure stays up at a stop, the solenoid or governor body is at fault. Before buying, confirm the transmission relay supply and the sensor ground, and look for a chafed harness near the pan rail. Our 47RE governor pressure solenoid symptoms guide lists the codes and tests, and the Ram 2500 Cummins common problems guide covers faults that feel the same.
The listing covers 2000 and later A518 (46RE) and A618 (47RE) transmissions in Dodge, Chrysler and Jeep vehicles, which for the 47RE means the 2000 and later Ram 2500 and 3500 with the 47RE. The late sensor is rectangular and plastic-bodied; the 1999 and earlier sensor has an oval connector and needs a 1996-1999 kit. A replacement transmission may be a different year from the truck, so drop the pan and look, or send us your year and VIN before you order. The rest of the parts for this unit are on our 47RE parts page.
Drain and drop the pan, remove the filter and unplug the governor connector. The governor body bolts to the transfer plate and comes off without removing the valve body. Install the new solenoid and late sensor with the new housing gasket and lube the O-rings with ATF+4 first. The output speed sensor is changed from outside, at the rear of the case. Install the filter and new pan gasket, refill with ATF+4 and check the level hot. If gauge readings point at worn valve body bores rather than the governor, the 2000-2007 47RE valve body is the next step, and a tired, high-mileage unit is better served by the 47RE master rebuild kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, if it has the 47RE with the original late-style governor sensor. The kit is listed for 2000 and later A618 (47RE) and A518 (46RE) units. Check that your governor pressure sensor is the rectangular plastic type.
Not unless the transmission has the early sensor. Chrysler changed the governor pressure sensor for 2000, and this kit includes the late sensor, OE 56028196AD. The solenoid, output speed sensor, filter and gaskets are the same part numbers as the earlier kits.
Governor pressure that does not drop to zero at a stop. A sticking solenoid, a bad sensor, a leaking governor body or a missing output speed sensor signal can each cause it. A gauge on the governor pressure port shows which one.
ATF+4. After the pan drop, refill to the dipstick and recheck hot in neutral, since the converter and cooler still hold fluid.
No special relearn is needed for the governor parts. Clear the codes, then confirm on a test drive that actual governor pressure follows the desired value and reads zero at a stop.
