48RE Overhaul Kit 1993-97, new and ready to install. Fits the 48RE. Ships fast from the USA.
If you have an older Dodge Ram with the A518 four-speed and it has started leaving stops in second, skipping overdrive, or never locking the converter at highway speed, this kit is aimed at those faults. The listing is titled as an overhaul kit and carries the A518 reference, but what the product photo actually shows is an electrical service package: the overdrive/converter clutch solenoid block on its braided harness and round case connector, a governor pressure solenoid and a companion governor unit, a threaded plastic sensor, a clip, two springs, the governor body gasket, a felt filter and a pan gasket. There are no clutch frictions or piston seals in it. The 48RE title is the family name; the 48RE itself did not appear until 2003, and mid-1990s trucks carry the A518 (later called 46RE) or the heavy-duty A618 (47RE).
The 1993-97 span crosses a design change. The parts in this kit only apply to transmissions with the electronic governor, where a solenoid and pressure sensor mounted under the valve body replace the old mechanical governor weights on the output shaft. Earlier A518 units used that mechanical governor, and on those trucks the only electrical parts are the overdrive and lockup solenoids. Industry kit listings differ on the exact first year of the electronic governor by model, so do not order on the year alone. With the pan down you can see it: an electronic-governor unit has a small governor body with a solenoid and sensor plugged into the harness at the valve body.
On an electronic-governor A518, the PCM controls the 1-2 and 2-3 shifts by setting governor pressure with a pulsed solenoid, while the sensor beside it confirms the pressure that reached the shift valves. The 1998 Ram service manual describes that solenoid as working backward from what most people expect: no current means maximum governor pressure. The other half of the kit, the solenoid block, handles the 3-4 shift and converter clutch apply as two separate switched coils.
Make sure the overdrive switch is on and pull codes before buying anything. Because low pump output can look like a governor fault, read our pump failure symptoms guide and do a line pressure test first. The overdrive and lockup solenoid guide explains how to check those coils at the case connector.
Listed for 1993-97 A518-family transmissions. Per Sonnax, RE units through 1999 use the early oval-connector governor pressure sensor, which is the style that matches these years once the electronic governor is present. Confirm three things before ordering: that your unit has an electronic governor, that the sensor plug is the oval type, and that the filter shape matches the photo. Send your year and VIN if any of that is unclear. Browse related parts on the 48RE family page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only partly. The governor solenoid, sensor and governor gasket are for electronic-governor units. A mechanical-governor A518 can use the OD/TCC solenoid parts, filter and pan gasket but not the governor pieces. Check under the pan or send your VIN.
A518 is Chrysler's older name for the four-speed later called the 46RE. The heavy-duty version was the A618, later 47RE. The 48RE is the 2003-and-later evolution of the same family.
No. The photo shows solenoids, governor parts, the harness, a threaded sensor, springs, a clip, a filter and gaskets. Seals, sealing rings and frictions are not included.
Mopar ATF+4 or a licensed equivalent. It supersedes the ATF+3 used in these trucks when new. Set the level hot, idling, in Neutral.
On electronic-governor trucks, governor pressure sensor codes in the P1762-P1764 range and converter clutch circuit code P0740 point at parts in this kit, along with overdrive solenoid faults.
