    Q:
    What is the process for installing the Transmission Assembly for the 2012 Chevrolet Express? Posted by Romario C.
    A:
    Ensure the torque converter is securely engaged in the pump, applying a small amount of transmission fluid on the rear hub if removed. Install the torque converter onto the front input shaft while rotating it back and forth until fully engaged, checking with a straightedge to confirm the converter lugs are at least 3/4-inch below the mating surface.
