I took it apart to see if something could be bouncing around in there causing all the noise I'm getting...there wasn't and now I'm lost, #@&*+ again. I did mark position on flex plate before separating them in case that is what is balanced but need to know if I need to put transmission fluid in there during or after assembly...also where, how and what amount? I really feel stupid asking all these questions about engine (I do have Shop Manual for this car) but it tells nothing about this stuff. I would like to have engine back in car sometime this next week banging noise or not, just to see if it will once again run. Thanks again for help and patience.
