After a hard launch at the track this evening the car won't move with the shifter in OD. I can pull it down into 1st and it moves like normal. Reverse also works just fine. I haven't tried any other gears besides 1st and reverse. I didn't want to try anything else because it appears that I blew the posi also. Kind of a rough day!

Anyone have any idea what could be wrong? Could this be a pump issue? The trans is a stock 4L60E with a TCI 4000 stall and vacuum modulation installed. What should I check first?

You probably broke eitherthe low roller or the input sprag which either can easily happen when theres a rear end failure involved . You will need to replace or rebuild the trans

Do you think that I could have contaminated the converter as well? Looks like I will be calling you soon about a new trans.

That would depend on the failure i would go by what i see in pan on that
