Rear seal, shifter seal, lines to cooler, vacuum modulator, pan gasket.......front seal. Did you over fill it?

I think they take 9 qts. when dry. Run it and see where it is on the dipstick.

will jack up car tmrw and check trans lines etc and also convertor drain plug and bellhousing for signs of leaks
 
ok trans update got the car jacked up and on stands and there is a pretty bad leak at the bellhousing checked the convertor drain plug that is tight i now have dumped almost all the fluid i put in on the floor and can the seal leak so much or do i have bigger issues?
 
Some converters have two drain plugs.....sounds like bigger problems though.... Maybe a cracked case. I would pull the tranny and start looking.
 
guys is it possible ?

guys is it possible when the previous owner fitted the trans he might no have got the convertor seated properly into the pump if so can that cause major damage to pump as i had the motor running .
 
Yes, the pump housing, seal or converter could have been damaged if not installed correctly.
My guess is the converter was not fully engaged and the bell bolts were tightened to draw it up tight.
This will do damage to the trans causing a real big leak.
 
when I rebuilt my C6 the trans builder suggested I add 5 qts. then start the motor for 10-15 sec. shut off add another 5 qts. start motor for another 10 sec.shut off and top off the trans. He said the trans could not take the full 12 qts. in a dry trans all at once and if I added the full 12 qts. at first it would pump a few qts. onto the ground. not sure why but the procedure worked for me.
