Attention MT-82 victoms!!!
- Thread starter POSFTW
- Start date
No offense guys but a stiff muddy lever in cold weather is one thing. Grinding gears and unable to shift into a gear in a warmed up car... In sunny San Jose CA... is another. If your car has either symptom, just changing the fluid is a temporary band aid. Your clutch may not be fully disengaging (pp bolts backing out, hydraulics, etc). They're replacing my flywheel, clutch assembly, and entire transmission next week for these issues.
After reading all of this it makes me feel good to have an A6!
They are saying xt-m5-qs is like 10w40 motor oil not 75w90. they dont mention the tranny at all.
I dont believe xt-m5-qs is the correct fluid anyway. It was just what motorcraft has that they thought would work.
Since i switched to pennzoil synchromesh i have driven in 29-72 degree weather. Yes Florida winters are crazy like that. In all that fluctuation it hasn't ground once and has been sooooooo much easier to get in gear. The tranny isnt getting any hotter then normal (yes i was climbing under the car and feeling it) and no burning fluid smell.
Id try synchromesh first and see what you think, Ive had better luck with it. I took out the RP 75w90 due to having friction modifiers in it but i never had a grind with it just stiff but DEF better then stock.
We've been 10.39@133mph with the MT-82 and no problems so far. The car is on slicks and gets powershifted all the time. The car goes to the track tomorrow night again making a little more power..
so we'll see if can hold a 9 sec pass..
Here's a vid of our 10.39 for those that haven't seen it.

ilovestangsalot,
I am happy that you are trying the Syncromesh because I want to see what happens without trying it myself. I live in FL too.
If you look at their product sheet you will see that it is recommended in the trans that use atf like the tremec tr6060.
The GT500 uses that trans and Ford recommends their atf so they do have a similar product to Syncromesh.
I am not saying that it is wrong, but I would be concerned about long term wear at high ambient temps here in FL.

Advice to all, DO NOT use motor oil in your transmission regardless of what the lubricant manufacture has said. It contains detergents that standard gear oil doesn't and will cause adverse effects.
That said, 75w90 gear oil is roughly the same viscosity as 10w40 motor oil. Weight system between gear and motor oil are different.
Hope that helps.
I recommend 75w90 gear oil for those looking to replace the stock transmission fluid.
Just because they recommend it doesnt mean it is the best option available.
You telling me motorcraft 5w20 is the best oil you can put in your motor cause ford said so? I bet most people will say no. Same idea of thought there.
If the synchromesh fluid will work in a T56/TR6060, it shouldn't have any problems in the MT82. this tranny isnt some revolutionary design, its a tranny just made by a different company.
Grinding the hell out of the synchros everyday will wear out that tranny faster then a fluid that is a little lighter weight then recommended. People put lighter weight oil in there motor and still get 200,000+ miles out of the motor.
Honestly, I would try ATF before i put the stock stuff back in there. I dont think that is the right fluid either tho. It is just what they have. Alot of people around here with Tremecs swap there fluid to something else besides ATF. But that is what ford recommends OMG!!! lol and if ford recommends it, it has to be the best option available... HAHA yeah right.
If ford is looking into the fluid problem like alot of people are saying, then there has to be an issue or why would ford waste there time and money?!
I think I am going to send my car in to them, just to get it looked at at a minimum.
Everyone needs to STFU! Ilovestangsalot is the only that has listened so far, guess what, problem solved. I have 1 Barton shifter, 2 feet of ****ing snow in my driveway and 3 qts. of Amsoil Synchromesh under my christmas tree. I soon too will cure my tranny woes.
Take it for what its worth, don't be a pussy just fix your car. Seriously guys, I served this one to you on a silver platter, eat up.
Guess what black03! I too powershift the **** out of my MT82 at the track and it also shifts fine when powershifting, thats not the problem, thats just your shameless plug. You outright know there is a problem don't spin this like your MT82 is magically exempt because of vendor voodoo bullshit.
It is almost 2011 lets really start to enjoy our cars, just change the fluid!

Really?
Piss poor attitude, little to no credibility, and you expect everyone to take your word?
How old are you?
Run whatever you want in your transmission. Who cares. The correct fluid is 75w90 gear oil.
There is plenty of bad advise in this thread which is one of the reasons I joined this forum. It needed to be corrected. :nonono:
Well i have tried 75w90 and synchromesh. I told you my experience with both of them. There is plenty of useful knowledge on this thread, you just cant seem to find it cause of all the BS.
If it isnt related to a fix, fluid, or experience please stop posting crap as will I. This could have been a nice TECH thread.

As info:
I changed the transmission fluid today on my Mustang GT (4800 miles-7/29/10 build date). The fluid was a very dark reddish-brown. I replaced it with MotorcrafT XT-M5-QS (due to possible warranty issues in the future). The "new stuff" was very clear.
I do not understand how the fluid can turn this dark with so few miles! As a comparison, I had changed the fluid in my 2004 M3 at 45000 miles and the old fluid was only moderately brown--nowhere near as dark as the Mustang. It appears something is wearing in the transmission to cause this???
I am not having the shifting issues or grinding as of now. I did install the Barton shifter about 1500 miles ago which improved the shifting over stock.
As a side note-- I also changed the rear diff. fluid and installed a Drake differential cover. The old fluid was a very dark charcoal/black as compared to the new Motorcraft XY75W140-QL (clear) and XL-Friction Modifier (blue). Again, the M3 rear diff. fluid was a honey brown--not dark????

POSFTW,
I posted my experience with our car which has been very positive. If you don't like it maybe you should take your own advice. Our transmission shifts perfect on the street and at the track and doesn't make any grinding noises. What do I have to gain from telling you that? Nothing......
Happy New Year!
interesting....
Lets start to document who fixed their MT82 problems.
1.) Myself - Amsoil Synchromesh
2.) Ilovestangsalot - Pennzoil Synchromesh

3) jmatero - warranty :-D
As an outside observer and someone who doesn't have a horse in this race yet, it seems to me that the only thing you might have cured is a cold shifting issue. I would be interested to know if you still believe you have fixed anything after, oh, say 30k miles. What will the condition of the synchros, bearings, etc. be at that time?
All transmissions are not created equal meaning that different brands and models are built to different standards, clearances and tolerances and with different materials. Manufacturers recommend certain lubricants for a reason. As has been suggested by others, if you do have problems down the road and the manufacturer can prove that you did not use the recommended lubricant they might not honor your warranty.
Sorry but if you have grinding gears, can't get it into a gear, or have trouble modulating the clutch... Take it in. They're replacing my tranny, clutch assembly, and flywheel next Wednesday. POS (the name alone should scream WARNING) replaced his fluid and thinks he found the Holy Grail. Who knows. Ford sent their regional tech to drive my car. He said they're focusssed on the synchronizers and perhaps the fluid. If you've been grinding gears, you've damaged (to some extent) the synchronizers. The solution (at the moment) is to replace the transmission.
Ford used my car as a test... They added friction modifier after discussions with my service manager. He's been putting friction modifier in his own GT500s with great results. It definitely helped... For a while... Then right back to square one.
If you have a new car and you are not happy with the transmission and/or clutch... Notify Ford Customer Care, get a case number, and bring it in to be evaluated. Personally, the idea of buying ramps, crawling around on my back, unplugging solenoids, and replacing gear oil on a brand new car I just paid close to $40k for is NOT an option. Just my 2cents.
