Can you verify the correct pump castings were used? On the front of the pump there should be a casting number. It will end in 149, 082, or 690.
The stator should have a casting number on the inside as well. It will be 150 or 088.
If they are mixed up, weird things could possibly happen. It is worth cking out.
Hope this helps
You got a good one. I would also ck to see the stator shaft is installed correctly. Make sure bleed hole in guide pin is open. These are just some things that come to mind.
If you wish to confir more on this, call me and we will try to figure this out.
one other thought was the TCC valve is in backwards.
Just thoughts
