4r100 no go

I just installed a Tony Wildman chip in my 99.5 7.3 AUTO. I let the truck idle until it was around operating temperature then left it in economy mode took off a little hard truck was running pretty good I let off and got on it again and heard a POP. Feels like it's in neutral now when I stopped and put it in park then in reverse or drive I would see the RPMs drop like it was going into gear it just revs though. Would this be the Torque Convertor?

I would remove the TW chip first to see if the problem goes away.
