Transmission fluid and filter

[got3fords]

The recommended dose is 1oz per qt, so a 15oz bottle is fine for the first treat. You don't want to go hog wild with it.

After the initial treat, it is just 1oz per quart whenever you change fluid again.

It also says on their website you can use it as an OEM ATF alternative.

What us 303 and 404?

303 makes auto/home products which have been proven for years. Best stuff out there for detailing your vehicles!

404 is just another wanna be cheap imitation!?

Duke, stick to making mayonnaise!?‍

Measure how much is drained and put back exactly the same amount...I hear the trans has 12 qt capacity but you can't get all of it out...my first drain I got 7 qt out...my second I was only able to get 5.5 qt...

.....torque converters hold a lot of fluid and don't give it up with a simple draining. With my old '99 Durango I'd fire up the engine after the initial trans drain. .....maybe wrung out a couple more quarts.

Is that safe to do with 10R?

I don't know, but I also didn't know if it was safe on the Durango and it didn't cause damage.
My rationale was the trans was assembled into the vehicle dry, and in the old days, gravity filled and started up. The internal pump in the tranny filled the converter.
In neutral with nearly no load on the TC which had plenty of residual lube for the bearings for the minute it took to spin out more fluid.
But there is always old fluid remaining. I did a quick search on the topic and found the following method that seems credible, although it requires extra fluid for the flush, and involves removing the cooler line at the radiator/trans cooler:

The DIY method is:

1.Drain you tranny pan (hopefully you have a drain plug, otherwise drop the pan and the whole nine yards that goes with that - might as well change your filter and gasket then).

2. Re-install pan (or drain plug), fill tranny to correct level of fluid without starting your vehicle.

3. Disconnect your tranny out line (usually the uppermost tranny line that goes to the rad). I disconnect it right at the radiator.

4. Attach a 5/16 inside diameter clear hose (about 6ft or so long) to the line you disconnected from the rad.

5. Run free end of the hose to a jug to catch any outgoing ATF.

6. Start your vehicle, put tranny in gear. You will start to see trany fluid flow through the clear hose into the jug now. Let a few quarts go in. Stop engine. Top up your trans.

7. Start engine, put tranny in gear, watch fluid in hose come out. When fluid comes out bright red, you are now pumped out most of your old fluid out of the torque convertor. Shut off and refill trans to correct fluid level.

This is the backyard tranny flush method and should get most of the old ATF out of your trans. I've done it several times, no problems. I usually pick up a 30 big pail of trans fluid at Walmart for $35 CN. Valvoline currently makes the Walmart Tech2000 auto fluids.
Hope this helps.

Found it, this is the filter that was on the truck when I bought it new, so straight off the line.

No flapper and I can't tell if the magnet was pinned on there or not. It can't really go anywhere and I think that's a plastic pin semi holding it in place. It can probably wiggle on there, probably what you're hearing.

This is what Ford/GM originally planned to do, but it was dropped early on.

Thank you, was curious as I had a 202 and could hear it and ordered one from Raybestos and you do not hear it with that one.

Couple things here.

Our trans fluid doesn't go to the rad, it goes to a small heat exchanger near the trans.

I'm not a huge advocate of breaking open factory hose seals and reinstalling. That's asking for a leak.

Please don't do this with a Walmart Fluid. Not that there's anything wrong with the Supertech fluids, its just that they don't make a suitable fluid for this transmission. If they had a ULV fluid, then sure, run that through the trans, otherwise no.

Drain and fills/vacuum and fills are still better than waiting till 150K to change the fluid.
