48RE Tcc Solenoid 2000, new and ready to install. Fits the 48RE. Ships fast from the USA.
Searching for a TCC solenoid because your Ram will not lock the converter at cruise, the tach sits a couple hundred RPM high on the highway, or the scan tool shows P0740 or P0743? This is a new overdrive/TCC solenoid assembly for the Chrysler RE-series four-speed, listed for 2000. As the photo shows, it is the complete pack: the two solenoids on their bracket, the internal wiring harness, the round case connector and the pigtail that runs to the governor pressure sensor. That is how the part is serviced, because ATSG treats the overdrive/TCC solenoid as an integral part of the internal harness and case connector assembly.
The RE units shift 1-2 and 2-3 hydraulically on governor pressure. The only two on/off solenoids are the overdrive solenoid, which makes the 3-4 shift, and the TCC solenoid, which applies the converter clutch. Per ATSG, case connector pin 1 feeds 12 volts to all three valve body solenoids through the transmission control relay, and the computer grounds pin 7 to turn the TCC solenoid on. On the 48RE specifically, Wayne Colonna of ATSG explains in Transmission Digest that the TCC solenoid is fed forward clutch pressure instead of second-gear oil, which allows lockup in manual 2nd and 1st and changes how a stuck solenoid behaves.
Scan first and separate circuit codes from performance codes. Make sure the truck is not sitting in tow/haul overdrive-off mode. Then unplug the case connector and ohm the transmission side: ATSG gives 25 to 40 ohms from pin 1 to pin 6 (overdrive) and from pin 1 to pin 7 (TCC), with no continuity from any pin to the case. If pin 1 has no power key-on, recheck with the engine running before you blame the solenoids, since the relay feed on these controllers is engine-run only. The full procedure is in our 48RE overdrive and TCC solenoid testing guide. Shudder with good readings is often fluid or converter wear rather than the solenoid.
Be careful with the year on this one. Sonnax dates the start of 48RE production to 2003, so a truck built in 2000 left the factory with a 46RE or 47RE, not a 48RE. The RE family shares this style of solenoid pack, but ATSG warns the harness is model sensitive because the governor pressure and temperature sensor went through four design levels with different connectors. Match the sensor pigtail connector and case connector on your old assembly to the photo, or send us your year and VIN and we will confirm it. If your truck is a 2003-later 48RE, compare against our 2003-2008 listing, and the full lineup is on the 48RE parts page.
Since the pan is already down, a 48RE solenoid and filter service kit covers the filter and gasket. If shifts 1-2 and 2-3 are also off, test the governor pressure solenoid on the same circuit; it should read about 3 to 5 ohms, not 25 to 40.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is the whole overdrive/TCC solenoid pack with its internal harness, case connector and governor sensor pigtail. The two solenoids are not serviced separately on RE-series units.
No. 48RE production started in 2003, so a 2000 Ram has a 46RE or 47RE. This style of solenoid pack is shared across the RE family, but the harness connectors changed over the years, so match your old part or send us your VIN.
P0740 and P0743 on the TCC side, P0753 and P0783 on the overdrive side, and P1740 for TCC or overdrive solenoid performance. Test the circuit before replacing, since a dropped transmission control relay causes several of these.
ATSG gives 25 to 40 ohms for both the overdrive and TCC solenoids, measured from case connector pin 1 to pins 6 and 7. The governor pressure solenoid reads about 3 to 5 ohms.
Mopar ATF+4. A non-specified fluid can cause poor shift quality and converter shudder on these transmissions.
