ATS Diesel 1996-2007 Dodge GM Governor Pressure Solenoid Block Conversion Kit
The ATS Diesel 303-100-2188 is for the 1996-2007 Dodge Ram owner whose 46RE, 47RE or 48RE keeps eating factory governor pressure solenoids. The usual complaint is a truck that takes off in second, shifts late and hard one day and early the next, or refuses to drop back to first at a light, often with a governor pressure code on the scan tool. ATS replaces the factory solenoid and its cast housing (Mopar 4617210) with a precision cast aluminum manifold carrying a heavy-duty GM-style solenoid. ATS rates that solenoid at six times the force of the stock part, which is the reason diesel owners who tow choose it over another factory replacement.
These RE units still make the 1-2 and 2-3 shifts with hydraulic shift valves. Governor pressure is the road-speed signal that pushes those valves toward the upshift, and since 1996 it has been produced electronically instead of by spinning weights. The computer pulses the solenoid to bleed line pressure down to a target, the pressure sensor reports what actually came out, and the computer corrects. Pressure should be near zero at a stop and rise with road speed. If the metering valve sticks or the coil is too weak to control it, the shift valves get the wrong signal and shift timing goes wherever the pressure goes. ATS points to exactly this weak factory solenoid as the reason for the swap.
P1762 and P1763 point at the pressure sensor circuit as often as the solenoid, and this kit moves your existing sensor into the new block rather than replacing it. Watch desired against actual governor pressure on a scan tool, then confirm with a gauge on the governor test port. If actual pressure sits above zero at a stop while the sensor reading agrees with the gauge, the solenoid is not bleeding off and this block is the fix. If the gauge and scan data disagree, replace the sensor first. Our 48RE governor pressure solenoid symptoms guide covers the codes in detail, and the 48RE valve body testing guide explains worn governor plug bores that can feel just like a bad solenoid.
ATS lists this kit for 1996-2007 Dodge and Chrysler 46RE, 47RE and 48RE transmissions, gas and diesel. Most buyers are running the 5.9L Cummins: the 47RE through 2002 and the 48RE from 2003 to 2007. It bolts to the valve body in place of the factory governor body, so the truck must already have the electronic governor solenoid and pressure sensor under the pan. If your transmission was swapped or rebuilt and you are not sure what is in it, drop the pan and look, or send us your year and VIN before ordering. Every other part for these units is on our 48RE parts page and the 47RE parts page.

Yes. ATS lists it for 1996-2007 Dodge 46RE, 47RE and 48RE transmissions, which covers the 2003-2007 48RE behind the 5.9L Cummins. It replaces the factory governor body, so confirm yours has the electronic governor solenoid and sensor under the pan.
No. The ATS block comes with the GM-style solenoid and gasket, and you move your existing pressure sensor into it. If the sensor has set P1762 or P1763 or reads differently from a gauge, replace it at the same time.
It will if governor pressure is staying up at a stop because the factory solenoid is not bleeding off. Confirm with a gauge on the governor port first, since a bad sensor, a harness fault or a missing output speed sensor signal can cause the same launch.
No. The truck's computer still drives the solenoid the same way. Clear the codes after installing and check on a drive that actual governor pressure follows the desired value.
ATF+4. Refill after the pan goes back on, then check the level hot in neutral and top off as needed.
It is a pan-off job that does not require removing the valve body: four bolts and two Torx screws hold the governor body. Most of the time goes into draining, letting the valve body drip and cleaning the pan.
