Attention MT-82 victoms!!!

Although a manal tranmission is pretty much the same to another manual transmission mechanically, I wouldn't generalize your thoughts like you have stated with fluid. The type of materials used in the transmission, mainly speaking with the syncros, will dictate what kind of lubricant will allow the transmission to work properly (this is the reason the T5 "world class" transmissions and newer T5's use ATF and the older, regular T5's used gear oil). It's good that you are testing out different lubricants to see the reaults, but don't think what works for another design transmission will work for any other. Also, if your going to go through the trouble of this testing, I would go for a long useage interval to make sure the problem is still resolved as the specific lubricant you are postulating that works right is used.
Ford may not look into a problem just because it really is one that would yield destructive results. Ford will look into a problem because it's consumers are not happy.
For those of you commenting on used fluid colors, a lubricant will get dirty/darker after use, say close to around 1000 miles. It will. Also, another thing I want to mention, there are three ATF's that will turn brown or even black under normal use (I know we are talking MT's but Im throwing this in for another point of view). Im talking less than 1000 miles. These fluids are Mercon LV, Mazda Specific and Ford's Premium ATF. These fluids are used in the 4R70/75, the 6R Transmission (6R80, 6R140..etc), the FNR5, 6F Transmissions (6F35) and the Aisin.
When you add friction modifier to a rear axle the fluid may change color as well.

wow what a cluster ****.... i just wanna say what ever ford figures out they better fix mine if it does get all stupid and not wanna shift. for you who talk about credit YOUR ONLINE YOU ****ING RETARD!!!! like the number of posts is how much credit you have? how old you are makes you have more credit? NO!!!
auto trans fluid will look darker after use due to the clutch material breaking down and turning the fluid darker in color inside of a auto trans. I dont believe a manual fluid will turn that dark in 3000 miles because there is alot less broke down materials being diluted in it.
I agree synchro material will play a huge roll in the fluid choice. That is why i removed the RP gear oil because it has friction modifiers and ford obviously thinks FM will damage the synchros from what they have stated to the shops using it.
All in all i have alittle over 300 miles on the synchromesh and havent had a single grind, hard shifter, or refusing to down shift. which happened on a daily basis with the OEM fluid in there. But the true test will come when i have thousands of miles on it, I will gladly unbiasedly update along the way. I have had one friend switch his fluid in a 11 GT/CS and it fixed his as well be we both dont have tons of miles though. Is it a band aid or true fix? who knows but it works for now and better on the trans then grinding gears all the time.
Great.
Thanks for the testing you are doing and for the results you are posting. Seriosly.
When I first heard of this problem, I thought to myself that when I get my car, I am going to at least change the fluid to Ford's Synthetic MT lube if I find any shifting issues unrealted to the clutch; see what happens from there with what Ford says should indeed be in there. I was actually considering Red Line GL-4 70W80 over that.
As for the fluid color with auto transmission - I know. What I am saying is that those 3 fluids WILL turn BLACK after very limited use. I mean BLACK, not dirty. Anyway, this was just aimed at saying it is unknown what chemicals are all used in Ford's Synthetic MT lube. I've never heard of ATF tunring BLACK unless it was really old or the trans had internal problems (overheating problems, badly slipping cltuches, etc). Yet LV, Mazda Spec, and Premium ATF does. Someone said their diff fluid was dark... OK. If you have over a thousands miles on the diff fluid and had FM added, the lube can normally be dark.

You directing this to someone specific?
No problem being the geniuea pig LOL Redline getting great reviews. I threw in cheap synchromesh just to test and not waste alot of money if it failed. i will prolly drain it at 10k and inspect for more then usual shavings and coloration. As long as i dont run into any problem on my way 10k, then replace it with a name brand synthetic equaliant.
Thank you for complying ideas and brainstorm, that is exactly what we need. So hopefully we can fix this problem. :dancenana:
FYI:
Brought the car in for the flywheel/clutch assembly/transmission replacement this morning. Just got a call saying Ford Engineering intervened and asked that the dealer pause the repair. They said in order for the problem to be solved for good "6 newly designed bolts" (I assume for the pressure plate) need to be ordered (limited supply.. on backorder) and XT-11-QDC fluid should go into the new transmission. Ford engineering is confirming that XT-M5-QS should NOT be used... XT-11-QDC (as listed in the owner's manual) is, indeed, the correct fluid.

Thank you for the update. Great info, the ford tranny quick reference is wrong then and manual is right. Interesting.
very interesting. if this is indeed true, then a recall must be forthcoming...
so we need ot change our fluid asap? awesome i need a drain and refill anyways
Hold tight until I get my car back or Ford issues some kind of bulletin to dealers. As of right now, there is no fix. My car may be the guinea pig again... but I have my fingers crossed this is the solution. I think in my case, the synchros are damaged enough that a fluid change alone won't do a thing to help. (hence, the new tranny). It's interesting to note the label on the DCT fluid they're installing specifically states:
Motorcraft® Dual Clutch Transmission Fluid is specifically formulated to protect gears, synchronizers and bearings. It is manufactured with synthetic base oils and performance additives providing improved shifting at all ambient temperatures. Protects against wear and corrosion, while low viscosity improves fuel economy
Sounds perfect to me! Stay tuned!

That is really weird considering the XT-M5-QS is not just in the owners manual, but in the Ford workshop manual. Even the online workshop manual version, which gets updated.
One thing I am very curious is to which engineer said this. There are Engineers for Ford and than there are Field Service Engineers from the Hotline. I know many times the FSE get confused for the actual engineers. I would hold tight on the fluid guys. FSE's can be wrong as I've seen several times.
I want to add, if this is for sure what Ford's drivetrain engineers, not an FSE, has come to in conclusion, there will be a TSB or SSM out very very shortly. Suprised this action is getting taken without a TSB or SSM.

Actually, page 309 of the owners manual states the MT82 transmission takes XT-11-QDC. In my case, the Field Service Engineer who has been assisting my Service Manager heard back from Ford's Drivetrain Engineers who said "STOP".
No way of telling what shipped from the factory but if you had work done and the dealer replaced the fluid we can only assume they followed the manual an added the non-DCT. If the issue was fluid, they will issue that as a fix for the shifting issues.
Dont our cars have 8 bolts?
Nope. All 2011 Mustangs use 6 bolts.
According to the service manual:
▪ Fluid should appear reddish in color for the TR6060.
▪ Fluid should appear amber to dark amber in color for the MT82.
▪ Fluid should appear reddish in color for the TR6060.
▪ Fluid should appear amber to dark amber in color for the MT82.
I, too, have grinding issues when warmed up. It grinds going into reverse, and I sometimes get a grind from 1st to 2nd and 2nd to 3rd. Also, I have a whining noise coming from the gearbox in 1st through 4th gear. 5th and 6th don't whine at all. It literally sounds like I have a twin screw or roots blower on the car.. that's how loud it is.
If you don't mind, can you please PM me the name and number of the dealership that you're working with. Also, can you PM me what's going on with your car? I'd like to have some "ammo" to take the dealer, so they don't try to just shrug this off.
Thanks,
Travis
