    Transmission Temperature Question:

    I've noticed that my transmission temperature runs quite a bit higher (25 degrees) in 5th gear than it does in 4th gear (for the same driving conditions). Any suggestions as to why this may be?

    Servicing the transmission valve body

    I have a 2006 2500 sprinter and I'm replacing my torque converter. There was a bunch of sludge at the bottom of the pan. No chunks just sludge. Do I need to service the valve body or will new fluids flush out the valve body? Bryan
