How to transfuse your A4LD transmission.

[don-ohio]

Here's how I did it:
THIS is for Aerostar....but you can modify the deal to fit most trannies.
Okay......unfortunately the Aerostar doesn't have a torque converter drain as you well know so THIS is how I got around it àn did a good flush.WARNING! It's messy! Wear old no-good clothes or an old raincoat.LOL!
(1) Put the van SECURELY up on staads or better yet,blocks high enough that you can slide a 2.5 gallon or bigger bucket under there àn have 4" of clearance above it to the trans pan.Set it aside for later.
(2) You'll need one of those large flat drain pans from Auto-Zone about two feet by 3 feet to center under the tranny pan also.
(3) Okay, now you drain the fluid the regular old way àn get the pan out of the way.
(4) You now have a filter you're looking up at which has a suction hole there àn THAT is what you'll either clamp a hose to or you'll have to hold it in place later(I have a perfect hose that's flexible,about 1"diameter that I think I cut off a washing machine drain hose).
(5)This hose will need to be proper length to reach ALMOST to the bottom of the bucket from the filter attachment.
(6)NOW you're gong to fill that bucket up with nice clean fluid àn slide it into position under that filter hole.
(7) Okay,if you're in a garage,open the door for fumes.
(8) Either clamp your hose or hold it up TIGHTLY to the intake hole of the filter,the bottom of that hose extending into the fluid ALMOST touching the bucket's bottom
(9) Have someone start the van àn prepare to get fluid on you. Tell them in advance to have their window down so they can hear you yell to shut it off when the fluid goes empty in the bucket.
(10) This will suck the fluid up,propel it thru the torque converter àn do a great,quick flush of the system.
(11) Now you only have to install your new filter,install your pan,àn add about 4 qts. or so thru the dipstick hole, àn CLEAN UP! LOL!
This is worth the trouble!You'll necessarily waste several qts. of fluid,but that's what it takes to do it completely,àn get that nice clean red fluid back again. don-ohio ^)

Don-Ohio you could have done it with clean coveralls, remove the pan and replace the filter and refill with clean fluid to the mark. Remove the out hose from transmission cooler and let it drain in a measuring bucket. Start engine for one minute while filing clean fluid through the regular filling tube. Do this as long as clean fluid comes from the out hose of the TMC; then your done. Re connect the TCM hose again and top of the fluid. That way the TC is refreshed too.

Too much mixing of fluid that way in my opinion

The flush I detailed forces the old out and the new in in a matter of thirty seconds or so. But to each his/her own! don-ohio
