the sierra came with several transmissions, the 4 speed and two versions of the 6 speed all six speeds have the tcm in the pan and contain all solenoids, the four speed is the 4l60-e and has an external tcm (transmission control module) and the torque converter clutch (tcc) is in the panand is intergal to the solenoid harness
