    I have the trans cover off as I was seeing if there was an issue there so tomorrow will check the play.

    My concern is piston slap. Crossing my fingers.

    I checked the play on crank by prying the torque converter back and forth. Did not find any play at all. I would get a slight bang sound when the flexplate flexed toward the trans and torque converter moved back a tad.

    Find included the video of the engine. Did in drive and out.
