Torque Converter

[FastPro22]

I've read from my search here that if you only drain your Transmission oil from the plug you don't really get all of it out, unless you completely remove the oil pan. There was a post I read somewhere here from a guy who actually removed the Transmission Oil pan to drain out his oil. He only got 3 quarts out from doing that. Now our P5's takes about 7 to 8 quarts, right? (With every inch of oil completely flushed out from the Transmission). My question is that Torque Converter, how do you flush the oil from there? So you can get all 7 to 8 quarts out. I'm not very familiar with transmission so I do apologize if this is a stupid question.

I bought AMSOIL 2 1/2 gallon jug & took it to the lube place. They have a machine that will take in your oil (make sure they empty it 1st so not to comingle with other new oil) then after that they disconnect 1 of your lines, hook it up to the machine & hook 1 from the machine to trans, start your car & the machine sucks the old oil out seperate from the new as it pushes the new oil in. This will get all of the torque converter pan etc. - about 90-95% swap without comingling. There is a how-to on here somewhere about doing this at home 1-2 quarts at a time but I didn't like the old/new comingling thing & the possiblity of a mess at your house. They charged me 35.00 or 40.00 to do this. But AMSOIL synthetic atf is good for twice as long as regular. Plus I have an oil cooler so it should be good for at least 60k or so.

How to: Auto Tranny Flush

I used that how to.. worked perfectly.

Yeah that's the how to I was talkin about. Drain 1 qt which leaves 7, pour 1 new one in & it mixes with the 7 old ones then drain another etc. What percentage of new vs. old do you end up with after doing this 8 times? That's what question I had about this method........

Percentage?? All I can say is, by the time you add the last quart, if you can't tell the difference in the color of fluid coming out, then you probably didn't need to change it. I understand the old and new fluids mix, but you should just keep repeating the cycle until you get nice clean fluid coming out. It's plenty safe and much cheaper in the long run.

yeah.. just buy two gallons.. like.. $14 dollars to flush your own coolant compared to $80(Thats what they wanted to charge me here)

Just keep cycling fluid till it comes out clean..

Are you talking about the transmission, or the radiator??

... wtf is the thread about? transmission.. focus.

Well, the how-to was my second choice due to not having to work around other people's schedules to get help & the disposal of the old oil & the potential for a mess removing old oil then packaging oil for disposal. I just paid the 35.00 mostly to not deal with those things, took less time & because I could I suppose. Not saying I wouldn't or couldn't do the other or that is necessarily any less effective. Not paying anyone to do anything about coolant, that's a different simple non-mess.

your torque converter will hold a crapton of fluid... I wasn't aware how much until I had changed my own. the gradual flush is okay but after the 3rd or 4th time run it for a day or so to get all that fluid in the converter to mix up and disburse so that it gets changed too...

That's the reason I did it at the lube place. It pushes the new in & sucks out old while car is running in one shot torque converter pan & all no smell no mess all done & over.

Would you guys recommend this procedure? It's very similiar to the DIY Tranny flush as it was mentioned here. See attachment.

that's the standard procedure for a radiator flush if you have flushing equipment... its what Mazda recommends (as I understand it, though I never intentionally looked into it)

Guess I forgot to mention that it flushed the factory cooler line going through the radiator as well as the hayden transaver 20,000 lb extra oil cooler that I added. I have the cd manual too, been all through it. Didn't say any how-tos were complicated either. It was just more convenient & time saving for me to do what I did & yes time is money & I paid the 35.00 for the convenience, no possibility of a mess in my garage & not having to work around other people's schedules.
