    4r70w speedometer off

    You need to pull the speedo gear and see what color it is or how many teeth it has, then find the next higher tooth gear.

    Water pump pulley damaged

    I didn't reuse this plate when switching to the aluminum pulley from Spinning Wheels. Didn't use it with the stock steel pulley either. What purpose does it serve ?
