I'm on my second fill of this fluid. First was OE fill. Then I changed it out again at about 13K miles. I'm not real happy with the feel of the trans? Does not feel as good as I would like it to. Have about 14,500 miles now.

Amsoil Does not recommend anything they have. I have a 2016 Focus S with manual 5 speed trans. Anybody use anything else like Redline......gasp? My car is under warranty....... but I might try something else anyway. I have seen some mention of back a few years of using Amsoil European oil. But Amsoil has a few different European oils now.

Forgot to add, maybe the trans is not broken in all the way yet. Don't have any experience of a manual trans break in time/miles frame.

Your transmission is broken in. They really don't need a break in period.
Your transmission and shift linkage play a huge role how things feel.
Could be there is no fluid you'll find that will make much of an impact.
Boutique fluids aren't any better from personal experience.
It's hard to go wrong with Redline 75W80 MTL.
Pennzoil synchromesh fluid is cheap and works very, very good in front wheel drive manual transmissions from what I've read.

I changed the FF in my 2014 Focus 5 speed M/T at approx. 28K using Volvo 75W MTF which met the Ford spec. for their MT fluid (FORD WSS-M2C200-D2)....the tranny shifts great. I believe this fluid is identical to the FF since Volvo used the MTX-75 in some of their models. It's cheaper online than Ford's stuff....

This stuff also claims to meet the spec. I'll use it next time.

Yes I might be chasing the pot of gold at the end of the rainbow. I realize the Ford DCT fluid is supposed to be good. The trans just feels notchy in certain spots. If there is something that might be better, I'm willing to try it.

Any other thoughts on other fluids? I see the Ford/Getrag M2C-936-A on the Redline bottle. This trans is supposed to be the MTX 75 model that has been around for 20+ years or so. They were specing different fluid for it in other applications before. Oddly enough the Redline site does not list their DCT fluid when I plug my Focus into the product search finder?


This is about the only real info on this I have found:

Here is the list of things Terry Haines had recommended for that transmission:
"DO NOT USE ATF OR EP type oils in ANY MTX-75*
*Friction mod is not needed....unless 'you' have an issue with the lube...Stay away from it if you can*

*MY Choice of lubes in decending order:-

1. Motorcraft 'Full Synthetic Manual Transmission Fluid # XT-M5-QS ('honey')

2. Royal Purple 'Syncromax'

3. AMSOIL Synthetic 5W-40 European Motor Oil

4. (General) A Full Synthetic 5W-40 Diesel Engine oil...which includes:-

Mobil Delvac 1, 5w40 (full synthetic, a reformulated version of Mobil 1 which is intended for diesel engines)
Chevron Delo 400, 5w40 (full synthetic version)
Shell Rotella T (full synthetic version, not to be confused with Rotella SB synthetic blend or regular Rotella T non-synthetic)"Bob the oil guy)

Items 3 and 4 have too high a viscosity and does not have the proper additive mix for a DCT.

Item 1 has too high a viscosity for a DCT.

Item 2 does not have the proper additive mix for a DCT.

Apparently this Mr. Haines know little about MTF's.
 
OP has a five-speed manual gearbox, not a DCT. Ford provides XL-18 as an FM to add to QDC for the MT-82 transmission in the Mustang to get it to shift smoothly. XL-18 is straight naphthalene, according to the MSDS.

I suspect that if the OP used QDC and added XL-18 it would solve his shifting problem.
 
MolaKule I was thinking initially that the DCT fluid that Ford has was only for the Dual clutch ford trans. Not the 5 speed manual I have. But they spec it for both transmissions.

I was shifting today, and noticing that when I go from 1st, to 2nd gear it seems like you have to wait for the teeth to mesh before it drops into gear easily. Same thing going from 3rd, to 2nd, to 1st.

I'm thinking maybe I'm trying to shove it into the gear before it is ready. I'm hesitant to add a FM to the fluid. Afraid of the negatives it could have. But interesting about it helping.

OK, but it wasn't clear from his initial post that it was a non-DCT tranny nor an MT-82 transmission.

That doesn't add up.

Quite possibly or he simply needs to change fluid, and wait and see if it smooths up with a few more hours of operation. OEM MTF fluids do shear during operation.

A DCT fluid is simply an MTF fluid with an approx. 8 cst viscosity.

He wrote "I have a 2016 Focus S with manual 5 speed trans" but it was in the second paragraph.

QDC is a 6.1 cSt fluid, so it's pretty much an LV ATF viscosity with a DCT add pack. It works great in MT's but early MT-82's and now newly rebuilt MT-82's get XL-18 to make them shift better. That's a friction mod issue, and it's added at 1:100 to the base fluid (a 27ml bottle goes into 2.7 litres in an MT82). That naphthalene makes no sense doesn't surprise me, but that's what they MSDS says. $20 for 27ml is a heck of a price for mothballs, let's just say.
 
The owners manual for my 5 speed MT 2014 Focus (which I don't have in front of me) is a bit confusing when it recommends "DCT fluid" for the manual transmission. I'm nearly certain that the fluid used in the (terrible) DCT is different than the fluid used in the MT (despite the verbiage in the owners manual which seems to suggest they are the same).

What you need is a 75W, GL4 MTF.....a 75w-80 GL-4 MTF would probably also work....a dedicated DCT fluid would probably cause issues (as you seem to have).

Ford should have been more specific in the OM.

PS: Terry Haines wrote that years ago....I don't know if the MTX-75 in the 2014 Focus is identical to the MTX-75 in a 1996 Contour....

I still own a 1996 Contour with the 5 speed manual MTX transmission. Originally it called for Mercon ATF then I believe in 2000 they back spec'd the fluid in these older manual transmissions to the new Ford synthetic 75W-90 transmission fluid.

Here is list of MT fluids with Viscosities@100C from 6.X to 9.5 cSt:

NOTE: This list is only a “suggested” list of MTFs. It is not an endorsement of any one fluid, nor is it implied that any one fluid will cure problems in MTs that have design problems or those that have excessive wear.

A.

2. Redline DCTF Dual Clutch Transmission Fluid (8.1 cSt)
3. The next higher viscosity would be BG Synchroshift II (8.2 cSt)

Digging up an old post - I am changing the gear oil in my the MX-75 in my (now) son's 2013 Focus w/5-spd. Ordered 3 qts of the Motorcraft XT-M5-QS manual gear oil before doing the typical online homework or checking my manual - was interesting that Ford shows the DCT fluid for both transmissions. I've changed the fluid in my VW DSG including UOA/VOA with Liquimoly's offering and it seems to be quite a bit thinner than what I am accustomed to for a manual trans oil - not sure what I should do?

XT-M5-QS is Ford's 75w90 GL4

The DCT fluid is a 6.5cst GL4 75w (BOT 350)

Pretty drastic change by going to a ~15cst from a ~
I would return the 75w90... unless you're commuting thru DeathValley and have built a 500hp engine. Use the correct or similar fluid.

Or, did Ford try to solve a poor quality shifty transmission with the 75w after everyone complained about 75w90.... If so, you can more than likely get away with ANY GL4 from 6-15cst!

Use the GL4 75w.... Redline MT-LV or Toyota GL4 75w if you don't want the OE Ford fluid.

I might step up to a mildly thicker MTF/MTL GL4 in the 7-10cst to see how well it works in your transmission. Valvoline's ~9cst MT synchromesh fluid is a GL4... Redline MTL, Amsoil MTF, BG Syncroshift II, Triax GL4 75w80, RoyalPurple Synchromax are some others...

If shift quality is an issue.... might need to adjust/upgrade shifters, bushings, linkages, cables, mounts, fluid bleeding, accumulator removal if equipped, whatever available for you MTX75/vehicle....... yes... soft wornout drivetrain mounts could cause shifting issues. And, most OE shifters are NVH tuned rubbery nightmares... not much you can do.

I am goign to go with the correct DCT fluid and return the other, easy to do and I prefer to use what the manufacturer recommends.
 
Just went to the Ford dealer and picked up the DCT fluid that is listed. Returned the old-school gear oil to Amazon.
