How difficult is it to change the selonoid pack on a Dodge Ram 1500,4.7,2wd .I would like to do it myself

Pretty sure yours is inside tranny, drop pan and remove valve body, there it is. replacing it in and of itself is easy, but valve body has all those springs that tend to pop around when removing valve body, do it carefully and keep a sharp eye out. take pics all along the way if you've never done it before so you can get assembled properly again
