48RE Overhaul Kit 2000, new and ready to install. Fits the 48RE. Ships fast from the USA.
This kit is for a 2000 Dodge Ram with the four-speed RE automatic that has started misbehaving electrically: it leaves a stop in second, holds gears too long or shifts too soon, loses overdrive, or will not lock the converter on the highway. It carries the overhaul kit name, but the product photo shows the electrical and service parts, not seals and frictions: a filter, a pan gasket, a governor body gasket, the overdrive/converter clutch solenoid block with its labeled bracket and harness, governor solenoid and sensor parts, and springs. The 48RE on the listing is the family name. In 2000 the 48RE did not exist yet; a 2000 Ram has a 46RE with the gas V8s or a 47RE with the 5.9L Cummins or 8.0L V10.
First through third gears are still chosen by hydraulic shift valves, balanced between throttle pressure and governor pressure. Instead of a spinning governor on the output shaft, the PCM pulses a governor pressure solenoid to bleed line pressure down to the governor pressure it wants for the current road speed and throttle. A pressure sensor reports what actually reached the valves, so the system runs closed loop. Fourth gear and converter lockup are handled separately: the PCM grounds one coil in the solenoid block for overdrive and the other for the converter clutch. For the 2000 model year the governor pressure sensor changed. Sonnax lists 2000-and-later 46RE/47RE valve bodies with a late-style sensor that is plastic and rectangular, replacing the oval-plug sensor used through 1999.
Read the codes, then check the overdrive switch before anything else. A truck with a weak pump or worn clutches can mimic a governor problem, so a line pressure check is worth doing; the Sonnax pressure gauge guide lays out the minimum and maximum line tests, and our pump failure guide explains what low readings mean for this family. For the overdrive and lockup side, follow our overdrive and TCC solenoid testing guide. If everything checks out except one part, the single 2000 TCC solenoid may be all you need.
This listing is for the 2000 model year, which falls on the late-sensor side of the change. That also means a 1999-and-earlier truck should not use it, and neither should a 2003-up 48RE with its own updates. Model years do not always match the calendar build date, so the honest check is to look at the governor pressure sensor on your valve body. A rectangular plastic body means late style. If you are unsure, send your year and VIN before ordering. See every part for this family on the 48RE collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 2000 model year uses the late-style rectangular governor pressure sensor, while 1999-and-earlier trucks use the oval-plug sensor. Order the kit for your year, or send your VIN.
No. The photo shows a filter, pan gasket, governor body gasket, the OD/TCC solenoid block and harness, governor solenoid and sensor parts and springs. It is an electrical service kit, not a hard-parts rebuild set.
A 46RE behind the 5.2L and 5.9L gas V8s, or a 47RE in heavy-duty trucks with the 5.9L Cummins or 8.0L V10.
ATF+4. Check the level hot with the engine running and the selector in Neutral, and top up in small amounts to avoid overfilling.
There is no scan tool relearn. Clear the codes and drive; the PCM rezeroes the governor pressure sensor automatically every time the truck stops.
