42RLE Transmission Shift Solenoid Block Pack Kit

Remanufactured shift solenoid block for the Chrysler 42RLE four-speed automatic, sold under OE numbers 5143151AA, 04800171AA, 92887A, 49618A, 44956, 61711 and 61936A. The block is the electro-hydraulic pack that bolts to the face of the valve body inside the pan, and this one comes with the input and output speed sensors already fitted, so you are not robbing sensors off the old unit.

Fits the 42RLE application: Jeep Wrangler TJ and JK, Jeep Liberty KJ and KK, Dodge Nitro, Dodge Dakota, and the rear-drive 2.7L Chrysler 300 and Dodge Charger. The 42RLE is the longitudinal four-speed with the electronic governor, so check the number stamped on the old block before you order - the 45RFE and 545RFE that share a lot of these platforms use a completely different solenoid pack.

The failure this fixes is the classic one. The pressure control and governor circuits inside the block go out of calibration or the internal wiring opens up, and the truck drops into limp-in and holds second gear. Along the way you get solenoid and speed sensor codes (P0750 through P0755, P0715, P0720), a 3-4 upshift that never arrives, harsh or delayed engagement into drive, and converter clutch cycling that will not settle. If the fluid is clean and the line pressure checks out at the tap, the block is where the fault lives.

On the bench it is a pan-down job. Drain the ATF, drop the pan, pull the filter, unplug the case connector, then unbolt the block from the valve body and transfer the gasket and any retaining clips to the new unit. Refill with ATF+4 only - this transmission is intolerant of generic fluid - and clear the codes so the TCM relearns its shift adapts. Every unit is stripped, cleaned, calibrated and flow-tested before it ships, so expect normal cosmetic marks on the casting; the solenoids and sensors are what get tested.
