connector on bottom of valve body
2001 4r70w whats the trick to getting the connector loose ,got 3 out of 4. but the one by the round solnoid wont turn loose.

 

If you're referring to #3 below, IIRC, it's just a snap fit. I didn't remove the rail when I pulled my valve body. I just disconnected the main harness connector. If you do this, though, just remember to push on all the connectors when you re-assemble it. (DAMHIK!)
