48RE Solenoid Kit 1998, new and ready to install. Fits the 48RE. Ships fast from the USA.
This kit is listed for 1998, and it is the complete pan-off service for the electronic side of a 1998 Dodge Ram automatic. The product photo shows a governor pressure solenoid, a governor pressure sensor, the overdrive/TCC solenoid assembly on its internal harness with the case connector, a threaded sensor, two springs, a retaining bracket, a governor body gasket, a transmission filter and a pan gasket. If your 1998 Ram is shifting at the wrong speeds, starting off in second, refusing fourth, or never locking the converter, this covers every electrical part that usually causes it in one order. The listing uses the 48RE name, but a 1998 truck has a 46RE (gas V8, 1500 series) or a 47RE (5.9L Cummins and 8.0L V10); the 48RE came later, in 2003.
Chrysler's 1998 Ram service manual lists the governor control parts as the governor body, the valve body transfer plate, a duty-cycle governor pressure solenoid, a governor pressure sensor with the fluid temperature thermistor built in, plus the throttle position sensor, the output speed sensor and the PCM. The solenoid turns line pressure into governor pressure for the 1-2 and 2-3 shifts, and the sensor tells the PCM what it got. The overdrive and converter clutch solenoids are a separate pair on one bracket. ATSG gives the case connector layout: pin 1 feeds 12 volts to all three valve body solenoids through the transmission control relay, pin 6 grounds the overdrive solenoid and pin 7 grounds the TCC solenoid. That shared feed is why one fault can kill overdrive, lockup and the governor together.
Check the overdrive switch and lamp before anything else; a truck left in OD-off mode looks like a failed overdrive solenoid. Then measure at the case connector: GEARS lists the governor solenoid at about 3.8-4.0 ohms and the sensor at about 0.60 volts at zero pressure. With a 0-100 psi gauge on the governor port, the 1998 manual calls anything above 3 psi with the wheels stopped a fault. Our overdrive and TCC solenoid guide covers the 3-4 and lockup tests, and the governor pressure solenoid guide covers the governor loop step by step.
This listing is for 1998 Ram trucks. In that year the RE units used the early governor pressure sensor; Sonnax notes 1999-and-earlier units have an oval sensor connector, while 2000-later units changed to a rectangular plastic sensor. That makes this kit a poor match for a 2000-up truck or a true 2003-2007 48RE. Your build date also matters, since a unit built late in a calendar year can belong to the next model year. Look at the sensor plug and filter shape when the pan is down and compare them with the product photo, or send us your year and VIN. Browse everything for this family on the 48RE parts page; for 1996-1999 coverage in one listing see the 1996-1999 solenoid kit.
Rebuilding while the pan is down? The ATSG RE-family manual covers every valve body check ball and band setting.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
1500-series and gas V8 trucks used the 46RE. Ram 2500 and 3500 trucks with the 5.9L Cummins or 8.0L V10 used the 47RE. Both share the governor and OD/TCC solenoid design this kit replaces.
Yes. Along with the solenoids, the sensor and the OD/TCC harness assembly, the product photo shows a filter, pan gasket and governor body gasket, so you can do the full service with one pan drop.
It is listed for 1998. Trucks from 2000 on use a rectangular plastic governor pressure sensor instead of the early oval-connector style, so a later truck needs the later parts. Send your year and VIN to confirm.
Check the overdrive switch and lamp first, then confirm 12 volts at case connector pin 1 and a ground command on pin 6. If the circuit is good and the solenoid tests bad, the OD/TCC assembly in this kit replaces it.
No. Clear the codes and road test. The PCM recalibrates the governor pressure sensor zero point automatically whenever the truck slows to a stop.
