I have a built aod built by lentech and it acted fine on the dyno. But after running up the highway a bit and throwing my car a beating the trans feels like the lower gears are binding or reverse is kicking in when it shouldn't. If I put it in third it is fine. 1rst and 2nd gear act like reverse is fighting them and if I put it in reverse it will stall the car. Only does this after I go up the road and beat on it. After it cools its fine again.
