Sounds like a valve body issue to me. Problem with a "rebuilt" eBay valve body is all you can HOPE is that whoever rebuilt the valve body put all the spool valves, springs, plugs, ect. Back together correctly and the correct way.
What was wrong with your old valve Body?

Solved:
The rebuilt valve body on ebay was bad.
They used a older (pre reverse check-ball) valvebody steel gasket that was missing the second bleed hole. And they had installed a check ball. The attached image shows where both holes should be present, mine only had one.
With the check ball installed in a 1 hole valve body steel plate, it acts like a check valve and prevents any fluid from reaching the low/reverse servo when pressure is applied. The 2 hole design and check ball in the later style design were there to allow for gentle application of the low/reverse servo (small hole, and check valve applied over large hole) and a sudden release (both holes, check ball not applied)
