The Water Wetter [IMO] is one thing on the auto parts store shelf that really works.

OK; here`s how I did it in my `87. First changed the filter, & pan gasket. then I disconnected the top tranny cooler line at the radiator, & hooked up a piece of vinyl tubing to that line.I then SECURED the tubing to a empty gallon container ( Its better if you can have another person to hold the tubing in the container-ask me how I know
) After you do that, pour a gallon of new fluid into the trans, & start the engine. Let it idle. The old trans fluid will come out the tubing into your container. When the container fills up, shut the car off, dump the container, pour another gallon of new fluid into the trans, & do it again, until clean fluid comes out of the tubing into the container.Since you have the cooler line disconnected, the dirty fluid cannot go back into the trans. It can only go into your container. Easy HUH?

My wife has a 2004 honda pilot. According to the owners manual, the proper way to change the fluid is buy 12 qts. , drain 3 and refill, do this 3 times to flush the transmission. Now the total fill is 8 with the converter and we all know you can only drain the pan, which is 3. Do the math and doing this 3 times pretty much gets all the old fluid out.
IMO what you are doing is fine. Also, this is basicially the same way alot of us change the power steering fluid.

I have done that on my '88 but I don't have a '95. Press the other tab up top, then goto tech tips. There is a tech tip of it that explains a lot. On my car the fitting is right on top of the radiator by the coolant cap.

my concern with the top cooler line is you are still running the tranny low on fluid i understand not under a load but still i would start my car with out a oil filter to drain the oil pan

even though you are not running the trans dry you are running it low on fluid and if think a engine does not like low oil pressure or a lack of oil i can promise you that a auomatic transmission is a lot more touchy. not trying to start a fight i am just saying that using the trans line method does not sound like a very good idea to me

I'm sure there's a math major out there that can tell you how many quarts of new fluid it will take to make old fluid clean even tho you are mixing good with bad. I'm no math major but my guess is alot. Why not just take it somewhere and have it flushed and filled along with a new filter? Good luck.

I did this too only I started out disconnecting the top cooler line and pumped out a gallon. That way the pan was already pretty empty when I went to remove it. IMO there is no harm that can be done from low fluid doing it this way. The tranny is a lot more empty than that when it's assembled or overhauled and first filled.

yes you are correct about the transmission being empty when it is rebuilt but you also do not start the car untill you install transfluid so it just pumps the fluid up to where it needs to be and the last time i installed a tranny we filled the converter with fluid before we started the car

Why not take it to a transmission shop and have it powerflushed? They have a machine that sucks out all the old fluid and replaces it with new fluid. You should have the filter replaced, too.

Yes, your method will work just fine. Other members are just trying to inform you of a much easier and efficient method which has been performed flawlessly numerous times by others including myself for years.
Professional power flushing of your transmission will do more harm than good if your transmission has a lot of miles on it and is not recommended by many experienced transmission shops.
Also, according to my 1991 owners manual, automatic transmission drain and refill capacity is 10 pints or 5 quarts, a complete transmission overhaul is 22.4 pints or 11.2 quarts. Yours should be similar.

thanks guys i do not like the idea of a power flush. and i do not like the idea of the transmission being run low on fluid even not under a load but you know what your way does sound pretty simple just not for me. not trying to start any thing just telling my opinion
