Ahhh - you funny man Joe_Black!! ;Db;


If the above is true, then a peecee could not be a bus- but rather a very long subway, sanded & primed, left in a bad part of town with several cases of spray paint & stencils left neatly arranged ready to go....



;pg; sorry- couldn't let it go.....;pg;

Now off to do work (& not to fix things...)

I'd have to side with the professional flushers on this one. Aamco http://www.aamco.com/ (not Amoco!) will flush the trans for about $115. The thing is, they backflush it, so that debris can flow backword through the trans and out into the machine. If you drain and fill, you won't get most of the fluid. If you "idle and suck" new fluid in, you are still flowing forward, and a lot of debris can get jammed up in the valve body and other places. You also run the risk of running dry if you are not careful.

The filter is a screen. Leave the pan gasket in place, it will save you the trouble.

Power Backflushing is the best way to change the fluid. Unlike a radiator flush, which doesn't do a lot compared to draining and filling twice, the trans is different.

Don't forget to change the transfer case and the diffs as well. And don't forget the LSD additive for the rear (I think most VX's had Limited Slip Differential).

Happy motoring.

Finally got around to starting the "how-to" this evening. The only issue I've hit is that I can't find the TC plug. Anyway, got a bunch of pics and will hit it again tomorrow after work. Got some gasket scrapin' to do on the adapter pan!;Do;

The IronMan has been sitting with most of the tranny exposed for two weeks now and the most I've managed to extract is a little over 5 quarts. I'm convinced the remainder of what's reasonable to get out is tied up in the torque converter, but the 4L30E converter doesn't have a drain plug. I've rotated completely many times and one still hasn't appeared, even magically. Even the Mity-vac was unable to pull more than a few ounces of additional fluid.

So I most humbly offer my apologies for not being able to deliver on this one folks.:sighg:

I'll put up what I did accomplish and photograph on my website and will provide a link, which will hopefully help somewhat. Although I'm not giving up and will pursue more info on the 4L30E and DIY maintenance. I just wanted to update any waiting for this info as to my lack of success thus far.

Again, my apologies.

Joe, sorry man, but your quest is futile. The only way to get ALL of the trans fluid out is to pump it... and the only way to do it at home is to put extra lines on the cooler, one going to a bucket, the other going to a fresh supply, then idle the engine until the stuff flowing into the bucket runs clean.

There is another way; keep changing the few quarts from the drain plug over and over until the stuff starts to look clean... this could take hundreds of quarts, though...

Seriously, Aamco, the transmission folks, will get this done in a hurry, and for not too much money. It's like trying to service A/C at home, you just can't get it done right.

Sorry.

someone .......... mentioned to me that the torque convertor could be 'drilled' ........ a hole drilled into it - the fluid purged ..... and then plugged ..........
.
???
.
I would not try that in a million years .......
.
I like the idea of the Aamco flush ........ that appears to be an effective way to change all the fluid ......... and that is an easy way for Aamco to bring in some money with a small amount of labor involved .......... they don't need to drop the pan ..... and the crossmember and/or exhaust system, etc. if it is required ......
.
less comebacks due to pan leaks ........ etc etc. .........
.
regardless ......... I feel the filter should still be changed .......
.
I will probably get the fluid flushed - and then drop the pan, change the filter, and add new fluid to top it off.
.
btw: beware of Aamco ....... that organization has been in trouble more than a few times ..... the ones in my area had a rotten reputation ........ Two examples: told someone they needed a new/rebuilt trans when a simple vacuum leak was the problem. Another time told someone they needed a new/rebuilt
trans when a $10 vacuum modulator was the problem.

t2p, changing the filter just isn't that critical since I hear it's a strainer, not a disposable element. (I don't know for certain).

You don't have to go to Aamco. You can have it done anywhere they have a machine. You may wish to avoid Ford dealerships to reduce your risk of a Type F fluid mixup. (I suppose aamco could screw this up as well).

Nate

The filter is more than a strainer and isuzu recommends changing it at intervals.

How can you backflush a trans, without dropping the pan, and get fluid out without dislodging gunk from the trans filter?

I'd almost think it would be best to change the filter before AND AFTER a backflush. I doubt that backflushing can remove the larger heavier particles, including metal, that a pan drop allows.

The pump in the service machine will backflush (push the fluid the other way) through the trans. If the filter is more than a strainer, then change it. You can change it as often as you like, but I'm just so happy to get clean fluid into the trans that I don't know if changing it twice is really necessary. Like anything else, more often is better, less often is worse, somewhere in the middle is likely okay.
