    1995 to 2007 Dodge, Ram and Jeep vehicles with the 40RE, 42RE, 44RE, 46RE, 47RE and 48RE automatic transmission often come in with contaminated governor pressure solenoids. This results in complaints of wrong gear starts as well as governor solenoid and sensor performance codes.

    The computer uses the governor pressure solenoid to generate governor pressure relative to road speed, emulating what the hydraulic governor did in older ‘RH’ series transmissions. The computer varies the duty cycle to the PWM governor pressure solenoid to achieve the desired output pressure. Simultaneously, it monitors the feedback from the governor pressure sensor to confirm that the governor pressure is doing what it is commanded to do. When the solenoid sticks or is restricted, the computer notices that the pressure reading from the sensor does not match the desired governor pressure and sets a code which puts the unit in limp-in mode resulting in 3rd gear start and no shift.

    Features and benefits:

    This TransGo governor pressure solenoid repair kit contains everything you need to take apart the original equipment solenoids, restore the valve bore, then replace the spool valve, spring and cap with new ones. The repair kit contains enough parts to rebuild six solenoids. This kit will only work on OE solenoids with the proper resistance value of 2.5-5.0 ohms.
