The aux vb
is that alum thing that is at the rear of the trans, right behind the main vb
, the one that has the tube coming from the pump that goes into it. Forward clutch feed.
As Crosley pointed out, swapping vb
and other parts can get you into trouble.
I would put the original stuff back on this trans. Along with the correct harness and switch.
As per your trans not upshifting, sticky TV valves are a huge problem for the 7ooR4.
For about $30.00 you can buy the Trans Go jr shift kit, which comes with a TV valve that will not stick.
Easy to install, has good directions as well.
Every 700R4 we build at my shop has this kit installed.
