The pan was never dropped! I didn't do anything internal to the trans. I've been calling around and was told to check crank play and make sure the flywheel is straight. I'll be doing that later today or tomorrow. I didn't do anything in the trans so everything should have been stock. I have a brand new transgo shift kit in the box sitting here on the bench but I'm not putting that in until I can at least get the thing running. The plan was to put a few weeks on the motor and trans before I start doing big mods. Good thing I made that plan! I'm all stock motor and trans other than headers (needed to fit the truck) and pulleys and I'm having all kinds of issues! 2 bad trans and now maybe bad crank play causing the trans to go....
