    actually they dont flush out 100% of the liquid... they actually recycle the old one and mixes with the new...

    only way to completely flush the old oil and install the new... is to drain it out the old fashion way...

    Auto tranny fluid change

    I changed my 3 speed transmission fluid and filter about a week ago (it was a pain in the ass-all those little freakin bolts pissed me off) anyway, i also know that there a SEPERATE differential housing with its own fluid...that has a fill plug and a drain plug-the fill plug is impossible to open with an allen wrench-theres no room-anyway, is it just fine to leave it with its old fluid-or should i get it done at a shop...

    Thats probably the only maintance thing I let a shop do because they have a machine that flushes out 100% of the fluid..

    what would you say was the hardest part-no doubt-ive "tried" to do it myself-after taking the left wheel off-and trying to maneuvor the allen wrench where you could remove the fill plug was a pain in the ass-so i just gave up...lol

    well, if the differential is a sepererate compartment-its not gonna be flushed w/ the main transmission--which i drained myself-so basically, like sean said, they have to do it the old school way...

    LOL you went about it the wrong way...

    There are two lines in and out of the trans which run to the bottom of the radiator. You need to disconnect the return line that goes from the radiator to the trans from the transmission itself. I don't recall which one this is and I may look later today if you need me to.

    Anyway, warm up your engine... get the car up to operating temperature then turn it off. Disconnect the line from the trans and put it in a bucket - this is where you're going to drop your fluid. Pull out the dipstick and put a funnel in the hole there. Crank your car (or have someone do it for you). You'll notice all your trans fluid pouring into the bucket... start filling while its draining. You'll see the change in the fluid color dumping. It should go from a dark color to a pink color again. When this happens you're flushed. I'd recommend letting it drain a little longer after you see new fluid showing. Should take you about 7-9 qts to flush it right. Once you're done turn off your car and reconnect the fluid line to the trans. Crank the car again and check your levels. Make sure all is well. If its too full, disconnect and drain some... if its not full enough, well fill it up more... lol
