Well this job wasn’t too bad from the bottom, was pretty awkward though. Pin fell out but was able to put into the new part and install it. New hose too.
I was contemplating doing this job from the top, but removing all the seats and installing new carpet at the same time.
But kinda glad I did it this way.
Had to use a small inspection mirror to find the nut to remove the heat shield and the nut that holds the bracket to keep the valve in place. It’s tight in there. Also have a small drain pain because atf will come out when you remove the valve, at least it did on mine.
But between the vacuum leak and burning the trans fluid in the engine, the truck runs much better now. Engine runs smoother and exhaust no longer smells terrible like it did before, especially in reverse. Trans is not as sluggish and shifts better, so glad I did this and it was cheap too.
Thanks to the OP for the pics and description, it totally helped me!
