44RE Solenoid Kit 2000, new and ready to install. Fits the 44RE. Ships fast from the USA.
Late-model 42RE and 44RE owners chasing a governor pressure code need parts that match the 2000-and-later electronics, and that is what this kit is built around. It is a heavy-duty solenoid service and upgrade kit for 2000-on A500/A518-family units, the four-speed found in Jeep Wrangler, Cherokee, Grand Cherokee and Liberty and in Dodge Dakota and Durango with six-cylinder and 3.7L engines. If yours starts out in second or third, shifts at random speeds, will not lock the converter on the highway, or keeps setting P1763 after someone already replaced the sensor, this box covers the electrical side and the service parts in one trip under the vehicle. New, and it ships from the USA.
Even in its later years this transmission makes its first three gears hydraulically. Governor pressure, made electronically, is the speed signal the 1-2 and 2-3 shift valves respond to. The computer duty-cycles the governor pressure solenoid to exhaust mainline oil, holding pressure close to zero at a standstill and raising it as the output speed sensor reports more road speed. Turned off, the solenoid sends full line pressure to the governor circuit, which is why an open circuit or a dead relay leaves the transmission stuck in a higher gear. The late transducer reports actual pressure and fluid temperature so the computer can correct its own command. Fourth gear and lockup ride on separate solenoids wired through the internal harness. The boost valve spring and one-piece retainer are hydraulic upgrades that go in while the pan is already down.
Gauge the governor port first. Per ATRA, a healthy system reads near zero psi at a stop and climbs with road speed; if it does, the shift problem is mechanical, not electrical. A solenoid that measures well away from about 3.8-4.0 ohms is suspect. Check the 12-volt transmission relay feed (P1765) and the sensor's 5-volt reference before blaming parts, and know that cheap replacement solenoids are a documented cause of a missing wide-open-throttle 2-3 shift. For lockup complaints, the converter lockup guide explains the circuit, and the governor pressure solenoid symptoms guide walks the same RE governor diagnosis.
Listed for 42RE, 44RE, 46RE, 47RE and 48RE units from 2000 on. The governor pressure sensor is the part that decides it: Sonnax notes that units from 2000 forward use a rectangular plastic sensor, while 1999-and-earlier units use an oval-connector sensor. A valve body swapped from an older unit could carry the early style, so check the connector on the part you remove. Send us your year and VIN if you want us to confirm. For earlier units and other parts, see the 44RE parts page.
With the pan dropped and the old filter out, the governor body is on the valve body. Swap the solenoid and transducer using the new body gasket and tighten the governor body evenly to avoid a cross-leak. The boost valve spring and retainer and the 3-4 accumulator spring go in during the same visit; follow the instructions packed with them. Fit the new filter, use one of the Duraprene pan gaskets, refill with ATF+4 and clear codes. If governor pressure still will not hold steady, the governor bore in the valve body is worn and a 2002-up Sonnax-updated valve body or the 2000-2001 version is the next move. For a full rebuild, add the 44RE 1998-04 master rebuild kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Usually not as packed. This kit uses the late rectangular governor pressure sensor for 2000-on units. Earlier units use the oval-connector sensor. Check the connector on your old sensor before ordering, or send us your VIN.
Because the pan is already down and the valve body is exposed, it costs no extra labor to fit the upgraded boost valve spring and the one-piece retainer, which is listed as an unbreakable replacement for the stock retainer.
Check the sensor's 5-volt reference and ground, the case connector and the internal harness, and the transmission relay. Transmission Digest documents chronic P1763 on these units that returned even after parts were changed. If wiring is good, replace the solenoid and sensor together and gauge governor pressure.
Yes, the overdrive and torque converter clutch solenoid with its harness is part of this kit.
ATF+4. After a pan drop, refill with ATF+4 and set the level on the dipstick with the fluid warm and the engine running in Park.
