Mike here is some info

For the 2006 model year there will be two versions of the 42RLE transmission. The new
variant (variable line pressure - VLP) of the 42RLE transmission, has a new case, valve
body and a variable force style solenoid (pressure control solenoid). The solenoid is duty
cycle controlled by the TCM to vent the unnecessary line pressure supplied by the oil
pump back to the sump. The system also contains a line pressure sensor, the line
pressure sensor is a direct input to the TCM. The line pressure solenoid regulates the
transmission line pressure and completes the feedback loop to the TCM. The TCM
determines desired line pressure based on current gear and engine torque to satisfy road
load conditions (similar to the 545RFE transmission).
2006 vehicles could be built with either variant. The new transmission can be identified by
the sales code of DGV or the new variable line pressure harness connect

how many miles are on this vehicle also give me the vin And i can telkl you which unit is in you vehicle

chat at ya later Ryan and Jim
