Well I am not well up on automatic tranny's, well that's a lie, cause I ain't up in the slightest on automatic tranny's. So when getting some ecumacation on line about fluid level in my B&M 727, I keep reading about the qt. quantity in the torque converter and how it effects qt. quantity in the trans over all. I'm assuming that the tq. fills at a slower rate and is filled from within the case which seems obvious enough, or fills when the trans is put in gear. Ok so far??? So now the idiot question: When I drop the plug from the pan and drain it, will that also drain the tq as fast as it does the case? I'd prefer not to drain the tq if possible. And I'm assuming that if that is at all possible (possibly because the tq drains so much slower) and the pan can be plugged off when say three or four qts. measured out, or will the draining slow way down. The real crux of this problem is I'm having a hell of a time with knowing when the damned thing is full or over full. I installed a Lokar tranny fill and stick. I could hardly read where it was on the stick so I painted it flat black on the end and that helped some and now I think it is over full so I'm going to drain the pan and start all over. I know this sounds like a damned fool question and sounds even worse for someone who is supposed to know what the hell your doing, even in rereading it, but what can I say?? Thanks for your help, next I ask about adjusting hydraulic lifters and the best way that is accomplished in my 331. I have of course have done this, but have been told it can be done on two cylinders at a time.
