Any way this brings me to think I overfilled the trans when I changed the trans a few months ago forgetting to drain the fluid it already had in it before putting fresh fluid in. I'm assuming the engine is sucking trans fluid threw the line that goes to the modulator down the intake?? So just curious as to what actually happens when a person over fills a trans.. thanks.
I dont know the answer to that ?, but what I like to do on a good tranny service is to rig a 2.5 gal gas can full of atf under and connected to pickup with hose(with pan removed) and suck the can dry.
This can make a big mess so put the gas contaner inside a larger(kitty litter) plastic tub.....
This will flush clean atf thruout trans/convertor....
Drilling and tapping a drain hole"aka MB" in convertor also a idea...
