46RE Governor Pressure Solenoid 1996-99, new and ready to install. Fits the 46RE. Ships fast from the USA.
A 1996-1999 Dodge Ram, Dakota, Durango or Jeep Grand Cherokee with the 46RE that holds first gear far too long, flops into second as you pull away, or will not come back down to first at a stop is usually telling you something about governor pressure. This set is the dealer-boxed answer: a genuine Mopar governor pressure solenoid, the matching governor pressure sensor (transducer) and the governor body gasket, for the early electronic-governor years only. The listing references OE 4617210 for the solenoid and 56041403AA for the sensor.
Up through 1995 the A518 used a spinning mechanical governor on the output shaft. For 1996 Chrysler moved that job into a small aluminum governor body under the valve body. Line pressure feeds the solenoid, and the PCM pulses the solenoid's ground to bleed that oil down to a target. The resulting governor pressure acts on the 1-2 and 2-3 shift valves, so the first three shifts are still hydraulic; the computer only decides how much push they get. The solenoid is inverse-acting per Chrysler's service manual: about 1 amp of average current gives zero governor pressure and no current gives maximum pressure. The transducer reads the result back to the PCM, which keeps correcting the duty cycle. ATRA's GEARS series on the RE family notes the PCM also needs an output speed signal before it will run the solenoid, and that above roughly 40 mph it hands off to full pressure.
Start with a quick electrical check. ATRA's GEARS lists the solenoid at about 3.8 to 4.0 ohms at 70F, and the solenoid's 12-volt feed comes through the transmission control relay, which Transmission Digest points out is only powered with the engine running, so do not condemn a dead-looking feed with the key merely on. Next, drive with a scan tool showing desired versus actual governor pressure and tee a gauge into the governor test port. If the scan tool and gauge disagree, the sensor or its wiring is lying; if they agree but miss the target, the solenoid or the hydraulics are at fault. On a sensor-voltage code, Transmission Digest found 1996-99 trucks setting P1762 from an overcharging alternator dragging the 5-volt reference up, so check charging voltage first. Our 46RE governor solenoid diagnosis guide has the full sequence, and the output speed sensor guide covers the input the governor logic depends on.
Listed for 1996-1999 Chrysler, Dodge and Jeep rear-drive overdrive automatics: the A500/42RE, A518/46RE and A618/47RE. These years use the early transducer with the oval connector. In 2000 the sensor became a rectangular plastic part, and the two styles are not interchangeable, so a 2000-up truck needs a different set. Mid-run updates changed some part numbers, so compare your old sensor and connector with the photo, or send us your year and VIN and we will confirm it. The rest of the parts for this unit are on the 46RE transmission parts page.
This is a pan-down job. Drain the fluid, drop the pan, remove the filter, unplug the solenoid and sensor, pull the retaining screws and slide both parts out of the governor body. Coat the new O-rings in ATF before seating each part so they do not roll or cut. If the governor body is separated from the valve body, clean both faces and use the gasket in the box. Refill with ATF+4 and set the level with the fluid hot.
With the pan already off, check the overdrive and lockup side too: the 1996-99 overdrive and TCC solenoid and the internal wiring harness live in the same space and are cheap to replace now. After the swap, clear codes and make several complete stops with warm fluid so the PCM can relearn the sensor's zero point. If shift timing still drifts with good pressure readings, worn governor plug bores in the valve body are the usual culprit, explained in our valve body testing guide.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing describes it as brand new original Mopar, the same set a dealer parts counter supplies, and it is photographed in the Mopar box with the sensor and gasket.
No. This set is for 1996-1999 units with the early oval-connector sensor. From 2000 on the governor pressure sensor is a rectangular plastic design, so ask us for the 2000-up version.
Unplug it and measure across the terminals. GEARS gives about 3.8 to 4.0 ohms at 70F. An open or shorted coil confirms it, but a solenoid can measure fine and still stick, so compare desired and actual pressure on a road test too.
The two work as a pair and see the same heat and debris, and both are already in this box. Installing only one leaves the PCM correcting against an old part.
ATF+4. Check the level with the engine running in Park after a drive, with the fluid at full operating temperature.
No scan tool procedure is needed. The PCM learns the sensor's zero offset at each stop, so clear codes and make a few full stops with warm fluid before judging the shifts.
