OK, I have a new BD Tranny, in for about 6 months now. Got on the highway, up to speed 60mph or so went to pass someone. Did stomp it for the tranny to kick down out of OD, but as I was easing up some it felt as though the tranny or driveline almost disconnected, stop pulling then BAM hard thump pulling again. It did it again about 5 minutes later then was fine. When I got to where I was going I checked the Tranny fulid level, it was extra high but with bubblews in it. Not foam but air bubbles. So what gives or does anyone have any sugestions

 

loose front belt, running a little hot, belt adjustment and running pressure increase, also make sure cooling line check /ball isnt partly plugged
