So months later I'm finally on a computer so I can post these videos. Most will not find my random post here and there so ill put some details so this thread is the go to

I'm a firm believer that Motul trans fluid cost me my trans and 2k. I have a pretty high milage ST, it being a 17 and i just crossed 78k. I feel most you guys do not have the issues I did because most you guys don't have the miles i do on Motul fluid.

0-11k OEM fluid
11k-50k Motul 300
50k-64k Motul DCTF

I might be off on the miles, I don't feel like looking for papers of when i did the change to DCTF, it was 40 or 50k. Either way you see I had Motul for 50k miles or so. I want to say for the last 10k or so I noticed a whine in all gears/no gears. It was at idle or driving. If the trans was spinning it was making noise. From pervious experience with bad clutches I was sure it was trans noise. But I kept driving the car cause I'm dumb, i should have took it in before 60k because at 64k it was over. The whine went from slight to super loud. It would growl and growl and on freeways it was crazy loud. One day on my way home I took these videos and that was the last time that trans ever made it a mile. While i was at speed i think the bearings finally gave way cause I heard something go blow up and made some horrible nasty sounds, and then I lost 6th gear, then 5th. Limped home and towed it from there on. Ignore the check engine light, it would come on once a week or so from a bad purge valve. Since i changed the PV it has never came back on. Anyway here are some videos and a couple pictures

New OEM flywheel, clutch kit, slave, and finally new seals to get rid of the leaking seals (which as we know they still leak lol just a lot less) and of course new brake fluid to flush the system. And oil and filter because its there anyway. As you see by fluid choices I'm not new to this game. I swore I was using top tear trans fluid

This is what my tech was finding in the trans fluid when he drained it


Here are the videos


This is when I noticed the noise getting louder. Just listen how it was 100% coming from the trans side

Sourced a new (used) trans locally for decent price. Here is what Motul cost me

11k trans - $900
Labor $500
Parts $430
Towing was free with AAA


And because I'm a sucker for pain, 10k later i swapped to Motul DCTF again....the shifts were so great again but 2k later i noticed a whine in second. I'm praying the damage is not already done. But i swapped to BG Syncro Shift II and have not looked back. Shifts are just as good, trans is quite again and I got it for free lol As we speak right now at 78, all is well. I believe Motul cost the trans, there are few cases of our cars going through whining trans. But the threads are far and rare. I blame the fluid, not Ford. Take it how you want. Motul will not be in this trans again.

Honestly can not remember when the nice started. I want to say before the DCTF


But the fact that there is another thread right under mine, with a guy who went through a trans at 10 with DCTF and that's how long I had it in mine. Hummmm I wonder

How much fluid did you put in each time you Changed it? 1.7L OR 2.0L?

I will agree with you Hardboiledegg...2L that shit! [wrenchin]

P.S Love you too Snickerdoodle!

You also need to add some flare to your vehicle by adding the colored Trim ring around that shift boot!

thanks for posting, sorry you went through this. my own anecdotal evidence is that my first fiesta chewed through transmissions - all on stock fluid (link). The car was eventually bought back by Ford under lemon law and i got a new one. 28k miles so far and no issues... but i literally just bought motul 300 last night! I need to do some more research i guess, but what is the difference between motul 300 and DCTF?

In basic terms, Gear 300 is more of a typical gear oil - it is thicker and similar to traditional manual gearbox fluids that you would find/put in older manual cars. The extra viscosity can lend itself to smoother shifting, but I'm on the fence about how effective it is at actually protecting the Getrag B6 in our cars. Being in a colder climate, I doubt I will ever try it.

Multi-DCTF is a transmission fluid developed specifically with dual-clutch transmissions in mind, so it is thinner than Gear 300 and has different film strength and shear resistance properties. Our transmission calls for DCTF-spec fluid and the OEM fluid is a DCTF type. Multi-DCTF supposedly meets the Ford spec for our trans as well.

I've been reading about numerous FiST gearbox failures and the most common variable seems to be a fill of 1.7l or less. OP's failure on Multi-DCTF with a 2.0l fill is concerning, but I do wonder if the 39,000 miles with Gear 300 did not contribute more to the failure than the 14k on Multi-DCTF that followed it.

I'm making no claims on the matter, but I am interested in others' input.

Sorry to hear that dude. I'm not defending Motul in any sense but I think you are getting bad luck with FiST transmissions. You just may be one of the few who've gotten oddball/black sheep transmissions. AFAIK the general public haven't had many problems with the FiST transmissions.

I'm at 18k miles on my 2017 and don't really think the shifts feel bad to where I feel the need to change to a different brand/type of fluid. I already have 2 quarts of OEM fluid ready to put in very soon. Don't see the need to change to something else.

How to make sure i get 2.0L of fluid in my tranny? and why the 1.7? is it hard to fill 2.0L?
Factory fill spec is around 1.6-1.7l, and this is also what the manual states to fill to. It's widely considered to be under-filled at that level, and is suspected to be done for fuel economy reasons. Filling to 2.0l is not hard at all. Simply drain the transmission and give it time to drain fully, then fill it with two 1.0l containers (or two 1.0qt containers to get ~1.89l, which is also fine) and don't worry about it - job's done.

To the above post about being unlikely. I agree against it because on the people who had failure. Far less miles, most are pretty new actually. My problems did not start till way further down the line.

The wording of this post is confusing me. Maybe I'm dumb, but could you please explain what you mean or are referring to?

Sorry I don't quite much


He was saying I'm just one of the unlikely guys who had trans problems. And I say no cause the few people who had issues were low mileage ones when they had issues. Mine did not happen till way down the line with Motul fluid in the trans. Is it possible? Yes


But I feel fluid is the cause, coincidence is too close
