transmission Bleeder valve idea
hey guys what up, quick idea i wanted to throw out. so i want to drain my automatic fluid but for the future i want to have a bleeder valve or screw instead of just the plug. stumbled upon a website that has that screw. apparently the drain plug dimensions are m18 x 1.5 10mm (found in another forum) so what if (i know this might be overkill) every oil change i also drain precisely with the bleeder screw 2 quarts of tranny fluid and refill with new? that way its just part of maintenance, you never worry about draining 4-5 quarts (even though theres still old fluid in torque converter) , and you always have clean fluid in your transmission. in theory you would always have new fluid coming in instead of waiting for 30,000 miles. maybe im crazy for the overkill but just seemed like a good concept.if you guys have any opinions i would love to hear them! heres the link to the product i spent hours searching for https://www.stahlbus-us.com/stahlbus...steel-set.html

This is one of the most original/unique suggestions I have read on here in years. Makes sense to do it when the car's already jacked up and it wouldn't add more than a couple of minutes to the process. It might be overkill as you mentioned but given the transmission holds over 10 qts. you'll be replacing ~20% ever 5K miles if that's your oil change interval. The only downside I see is Matic S/J usually hovers around $10/qt. but that seems like a small price to pay for the peace of mind to constantly refresh the fluid.
If you end up doing this please let us know how it turns out.

thanks for the feedback!!! read everyones suggestions, i think maybe every oil change you drain out a quart of tranny fluid from that bleeder valve i was talking about to keep it fresh. if its overkill for you then every other oil change would be perfect aswell. (helps keep costs down) i beat the crap out of my g so i dont necessarily want to drain 5qt but just every once in a while introduce new fluid. i change my oil every 3k (overkill for some) but yeah that bleeder screw instead of drain plug would make changing 1qt of fluid so simple why not do it you know? would it be bad if you had a bleeder screw on the trans where drain plug would be? can you use the same pneumatic vaccum pump that you use for brake bleeder screws to suck out MORE trans fluid or is that basically a flush? i cant say the same for this idea as a oil bleeder screw because we only do changes not one quart lol but yeah i figured since brakes have bleeder screws why dont other places where its changed more often or more complicated/ messier. maybe we on to something boys! Lets brainstorm!!

The volume of oil you want to move (1-2 qrts) and inability to build pressure (see brake pedal) makes a plug as opposed to a bleeder necessary. It's not hard to strip the plug in the trans pan. Dropping the pan and valve body allows for the replacement of approx 7. One could draw out fluid via a pump through the dipstick tunel.
I'd just stick to traditional methods and timelines. You'll be fine.

If you're willing, drop the pan & pull the valve body. The pan might contain another 1 qrt + and the vb 1/2 +. It's a lot of work and pulling the vb is a pita. I pulled the vb to install a shift kit and in all, 7+ quarts was replaced.
I'd drop the pan, clean the inside of the pan & magnets, then pull the plug a month or 2 later and replace what comes out. IIRC, the FSM reads something along these lines. Great time to ditch the oem oil and go synthetic if the trans is good and not too many miles and a good time to install a shift kit.
