I have not found a specification for the Motorcraft fluid, other than the Ford specific spec which searching lead me to nothing.ok, so here is my question now from all this reading I've done in the last few hours...if AW 1 spec is NOT the same as JS3309, then is the motorcraft fluid that you used AW1 spec ot JS3309?
it seems that the motorcraft is the same as Toyota from what I have read (so much conflicting info out there), which is the same as the mobil 1 3309. if so, we can use it. I will do some more digging tomorrow. you have some people saying that they have used full syn and it's great, some people saying that they used the mobil non-syn 3309 and it great, and then other swearing that you need to ONLY use the GM fluid. this is crazyI have not found a specification for the Motorcraft fluid, other than the Ford specific spec which searching lead me to nothing.
I honestly dont trust anything that isnt made specfically for these transmissions. Im not quite sure about the Motorcraft being the same as T-IV. Theres quite a difference in the fluids. The Motorcraft is a very slippery fluid, almost slippery like soap yet it clings to parts. When I took off the cap I was surprised to find that there was fluid stuck to the bottom of the cap. T-IV is not like that, thats more like engine oil.it seems that the motorcraft is the same as Toyota from what I have read (so much conflicting info out there), which is the same as the mobil 1 3309. if so, we can use it.

Certainly! Good questions. When I drained my trans from the drain plug on the bottom (i.e, taking out the big plug on the bottom) I got a hare over 2.5 quarts out. And I put in a hare over 2.5 quarts back in.Great original post, thank you! I think there are some details to work though though...
First, I don't understand how to reconcile the fluid level differences in the two fill approaches. I used the "pump it in from the bottom" approach... which took some fussing, with the right pump and tubing bits it really wasn't that bad.
When you do it that way, you get (from memory) about 1.5 quarts out when you pull the drain tube, and you pump about that much back in.
Here, you are still pulling the drain tube to drain, but you are pumping a lot more fluid than that back in (if I was reading your description correctly). So either the pump from the bottom approach is leaving the trans too low, or the fill from the top is putting too much fluid back in. Or maybe you didn't have the car level when you drained it all out thus not getting all of it out.
Then the fluid question is next. I got the GM juice, but if there is an $8 per quart Ford alternative, that's great. Even if it is a less "durable" fluid, I'd be OK with that as well, as I am changing the fluid to get junk out as much as I am to get fresh fluid in. More changing = more flushing. I'm thinking about doing a 1.5 quart swap each time I change the oil.
So great and clear post to ask the right questions to move this topic forward... thank you!
Thanks for that!Great thread, here is another nice little tidbit...
From this page:
• Fluid discoloration
• TCC clutch failure
• Improper fluid will not control TCC clutch slip rate and dissipate heat.
Correction: Suggested fluids
• T-IV or 1161540 for Volvo
• Mobile 1, ESSO or Castrol full synthetic are aftermarket alternatives
Which backs up your Ford fluid recommendation!
That tube may not have been put there to check the level, for all we know they couldve put it there to make our lives easier when pumping fluid back in from the bottomSo what is the correct fluid level then?
I assumed it was the top of the inner (taller) drain tube. That when you were at the top of that, the tranny was full.
Your documented process indicates about 1 quart more than that. Which matches what you observed from the last dealer fill. And it also matches what I observed when I first cracked mine open (bought used at 46k miles and immediately changed fluid because I suspect it was original).
So "1 quart above the top of that tube" seems to be how full it is from the dealer and factory, but then why on earth do they have that tube in there made too short in the first place?
exactly! the Volvo people ask for t-iv which is the same thing as the mobil 3309!!! this is redic. all I know is this...i',m not spending 25-28 bucks a litre on the gm/saab stuff.Certainly! Good questions. When I drained my trans from the drain plug on the bottom (i.e, taking out the big plug on the bottom) I got a hare over 2.5 quarts out. And I put in a hare over 2.5 quarts back in.
When you pump the fluid back in, you cant pump any more in than about a quart because the fluid will eventually spill over the drain plug/tube thing in the bottom of the trans. Unless all you did was take out the small drain plug inside of the bigger one and only got a quart and a half, that sounds like your transmission may have been over filled, because I maybe only got a quart out. I know that my transmission fluid was at the right level because it was changed at the dealer and I have a receipt showing that it only took 3 quarts. for a drain and refill.
And I can say the Ford equivalent fluid is works just as well as the GM stuff. After one flush, my transmission has been shifting great. It use to clunk a little on the downshifts because of the sticking valve body but the new fluid really helped get rid of that. ;ol;
Im going to do one more drain and refill this weekend for good measure.
And for further reading, if you anyone has the patience to read all of this:
It appears Volvo People use T-IV. I don't know what to think about the fluid any more
Also, it looks like Volvo has changed their specs in 2012 to say only use AW1 fluid and that the T-IV fluid is no longer approved. From that same thread:
Just be carefull, it seems that in 2012 or so Volvo said in the owners manual to only use "AW-1" fluid... So I have no idea.exactly! the Volvo people ask for t-iv which is the same thing as the mobil 3309!!! this is redic. all I know is this...i',m not spending 25-28 bucks a litre on the gm/saab stuff.
The AW 6 speeds were used in alot of cars. The Ford 500, which had a 3L V6 with 230Ft LBS of torqe or so I think, they also had an AWD version which (surprise surprise) is based on the same Haldex AWD system used in the Saabs... Same deal with the Cross over type cars, like the Mazda CX9, used the same trans, same fluid, and same AWD system.That PDF I linked also talked quite a bit about a lot of "software patching" to get the tranny to work right.
So the difference between Volvo / Ford / Saab may be how smart they made the ECM to "work around" wonky situations. Maybe Volvo made the software smart, and Saab just picked a more expensive but less fussy fluid.
How does the power of the Ford V6 motor compare to the Aero motor? That could be a factor as well. Perhaps the Ford fluid doesn't transfer heat as well, but it doesn't matter, because the transmission has a ton of margin. The Saab V6, with a turbo, is on the edge of the transmission spec and they put in better fluid to gain a little more margin.
All pure speculation of course....
I agree just did wife's trans just now. Both my and her car drained about 3 qts out first time changing. I refilled with 3 qts and all is good .So, just to tidy up the thread....
1) Drain transmission as much as possible by removing the entire two part drain plug assembly from the bottom of the transmission (torx bolt in a hex head tube that threads into the tranny).
2) Replace drain plug and put a total of about 2.75 quarts (2.6 Liters) back into the tranny (using either fill plug or vent).
3) Repeat 3 or 4 times, driving for a while between each, to effectively "replace" all the captive fluid and flush the tranny.
Nice and easy...
