changing trans fluid/ will this work?

[flair1111]

alright since it takes 24 quarts and the regular way of dropping the pan wont get it all out, how about blowing some compressed air (slowly) through one of the external transmission lines? would this get most of it out?

just a thought.

i wouldn't try it. compressed air can blow moisture in the trans causing bad things to happen. not to mention when the vehicle is off there is no flow in the trans, causing a lot of check valves to be closed. you could damage alot of things! mike

I agree that blowing compressed air through the ****** could harm things and destroy the ******. Haha, its cracking me up how many people are thinking of different things to try and flush their ******.

If you REALLY want to flush the ******, buy up around 15 quarts of ATF+4 and pour it into a 5 gallon bucket. Run a line from that bucket to the intake side of the ****** cooler line and have another bucket to catch the oil coming from the ******. Start it and let-er-rip. MAKE sure you dont run it dry. Have someone inside to shut it off when the clean oil starts to get low.

And idk how much pressure will be on that output side. May want a bucket with a lid and a hole for the hose. Make sure it doesnt blow out of the bucket.

or just do the basic drain and refill a few times over, each time it is mixing new with old, before long your mix will be mostly fresh.

Or just change it every 30k with a filter change and be done with it.

Never had problems doing it that way. Got a 42re in a grand that was said to be a 'bad' ******. Running strong at 170k and we still tow boats, jet skis, and campers with it.

A buddy of mine actually did that with manual ******. Don't know about an automatic though.

That's two completely different things,anyways there are no lines anywhere on the manual ******'s so he could not have have done that anyway.

I bought mine with 59,000 on it. It now has 65,000 on it. Is it safe to do a 60,000 mile ****** service? Line flush or just pan and filter?

I was looking to take the cheap way out and do something similar. After thinking about it, I decided it was much smarter to pay a garage/dealer to do a transmission flush, than mess something up in the transmission and have to pay to have it rebuilt.

I hate paying a garage to do stuff, but sometimes it's just a matter of having the right equipment.

I like this ideal the best aside from the more frequent changes which aint bad either.

what do you mechanics think about this if done with a careful eye? this seems to be the way to get close to a 100% clean fluid change if enough new fluid is in the bucket.

I never said he stuck it in a line. He put the air hose in the filler hole and blew it out of the drain to get as much out as he could to put synthetic in.

I did it that way once and I have a larger aftermarket external cooler that I thought made it a little easier. It was a bit of a PITA and had the potential to get real messy. Bottom line is I won't bother doing it that way again.
Drop the pan, let it drain for a few hours, seal it all up and refill. Good enough. Do that twice w/ a full syn ATF and you should Never have any fluid related problems. I honestly don't believe it is worth the trouble or effort to replace All the fluid during the change if you are running good quality fluid to begin with.
