47RE Shift Kit 1999, new and ready to install. Fits the 47RE. Ships fast from the USA.
A 1999 Ram 2500 or 3500 with the 47RE that drags a trailer for a living usually tells you its valve body is tired before anything breaks: Reverse takes a second to bite, the 1-2 feels long and soft with a load behind it, and the front band needs adjusting again not long after the last rebuild. This listing is a new Superior K500-618-L Shift Correction Package, the version Superior builds for 1999-and-later 42RE, 44RE, 46RE and 47RE units. The photo is the actual kit: valves, color-coded springs, drill bits, gaskets and seals in the Superior box.
The 47RE is the heavy-duty member of the RE family, built for the torque of the 5.9L Cummins and the 8.0L V10. Its valve body is mostly hydraulic. First through third are scheduled by governor pressure, which the PCM produces with an electronic governor solenoid and reads back through a pressure sensor, while separate solenoids handle the overdrive shift and converter clutch. Line pressure, and how fast it fills each clutch and servo, is set by the regulator and the valve body circuits. Under towing loads, every millisecond of slip during an apply becomes heat in the front band and the clutch packs.
The K500-618-L recalibrates those circuits. Its published problem list is premature band failure, inadequate line rise, slow engagements, premature clutch failure and a low 2-3 shift speed, and it adds a rapid-fill manual valve circuit so Drive and Reverse apply sooner. What separates it from the earlier K500-618 is a new governor pressure control valve. On these electronic-governor trucks, raising operating pressure can drag governor pressure out of the window the PCM expects; the new valve is meant to let pressure be raised for heavy-duty use without setting code 1763.
A shift kit fixes hydraulic calibration, not electrical faults or worn parts. Scan for codes first, then check fluid level and condition hot, throttle valve cable adjustment, and the governor solenoid and sensor. Put a gauge on the line pressure tap on the passenger side of the case, between the accumulators: idle in Drive should be in the low 60s psi, and pressure should climb with throttle. Low pressure that will not rise points at the regulator side of the valve body, which is what this kit corrects. Our 47RE harsh or delayed shifts walkthrough covers the pressure checks in order, and the Ram 2500 Cummins shift problems guide covers the governor readings that separate a calibration problem from a sensor or solenoid fault. If the truck simply will not take fourth, go to 47RE won't shift into overdrive instead.
This page is for the 1999 47RE, and the K500-618-L is made for all 1999-and-later 42RE, 44RE, 46RE and 47RE units, gas or diesel. A 1998-and-earlier transmission needs the earlier K500-618 package, which has no governor pressure control valve. Note that 1999 is the last year of the early 47RE valve body: Sonnax splits these at 1999-and-earlier versus 2000-and-later, and you can tell them apart by the governor pressure sensor connector, oval on the early body and a rectangular plastic plug on the late one. Check the kit instructions against the valve body on your bench, or send us the year and VIN and we will confirm it before it ships. Every part we stock for this unit is on the 47RE parts page.

No. It is built for 1999-and-later RE units. Trucks from 1998 and earlier use the earlier K500-618 package, which does not include the governor pressure control valve. Send us the year and VIN if you are unsure which unit you have.
Yes. The kit is listed for all 1999-and-later 42RE, 44RE, 46RE and 47RE units, gas or diesel, which covers the 47RE in the Ram 2500 and 3500 with the 5.9L Cummins or the 8.0L V10.
Preventing that is the job of the kit's new governor pressure control valve, which lets operating pressure be raised for heavy-duty use without setting code 1763. A P1763 caused by a failed sensor or wiring still needs to be diagnosed and repaired separately.
No. The valve body comes out from under the truck with the pan off. Many people still install the kit during a rebuild, because it will not fix clutches or a band that are already worn.
ATF+4. Refill, check the level hot in Neutral, and readjust the kickdown band and throttle valve cable before the road test.
The filter and pan gasket at minimum, plus the overdrive/converter clutch solenoid if it is original. If the clutches or band are burnt, pair the kit with an overhaul kit.
