Do not use rp in a tranny. It is meant as a race fluid only and there is alot of info online about how it eats thru gaskets. The oil is the same. What makes it lubricate so well is also what eats at your seals. It is a racing fluids. I have read many threads and independent testing about this stuff. Just because you haven't had an issue doesn't mean you won't. Especially suseptible is anywhere rtv gasket a has been used. Royal purple even warns against using it where rtv has been used as a gasket. Same thing with amsoil syncromesh. Now that I am an amsoil dealer it explains it in the dealers manual. Cork gasket takes longer but will also fall victim to failure. Do what you want but don't say you weren't warned.

Well thats promising! LOL. I have some warranty from the dealer I bought it from,
I just want to be informed before I go down, don't want to get BS'd by the dealer
into thinking its something less then it really is. Not sure what there going to be willing to do.
I'll keep you all posted. Does anyone think this Friction modifier will work?
All the searches i've done have people using it in there diff's, and not in the tranny.
Should I replace the fluid with some Royal Purple synthetic?

When I asked the service advisor about the stuff, he pointed it's use directly to the Quafi LSD,so it clearly was needed in those SRT4's.
Automotive engineers,specifically ones that specialize in drive train design/seem to have vast data at their finger tips as to what best works in specific transmissions... this by no means suggests they get it right EVERY time, but most of the time they do.Im wondering if this is one of those times/transmissions they have not yet got spot on.
My 2011 GT CS 6 speed manual has the same issue with grinding on 2nd 3rd,this happens pretty much every morning during the winter months,and lasts maybe 10 minutes... I usually fire it up at least 8/10 minutes before I drive away,yet it still happens,so I am doubting it's just a fluid issue.
Not sure yet how it is in warmer weather,I bought the car right on my B'day (9 October) and has done this right from new.
There is a very extended thread on another FORD forum with a ton of identical complaints,as a matter of fact there is a FORD rep that is actually (supposedly) helping a lot of owners with this particular transmission issue by the name of Dysha.
A lot of owners are quite disappointed with this happening on their new 2011 Mustangs,you could just read their frustration,post after post after post.
According to Dysha FORD still has no resolution on hand,bummer!

I had a Dodge SRT4,now sold, but dealer used to add friction modifier because of the Quafi limited slip,I remember this one time a rookie mechanic forgot to add it in and within 1 day I was getting definite grinding 2nd and 3rd... again as soon as it was added within another day the tranny was shifting like butter.

First time posting here. Please forgive me for by-passing the introduction thread for now.
With regards to your shifting difficulties, mine does the same thing when cold and less when warm.
Ford does have a TSB (tsb11-03-18, sorry could not attach) on the issue outlining that if any customers with 2011/2012 Mustangs with MT's that are complaining about cold weather shifting, the fix is swapping out the fluid and replacing it with Ford's QDC trans fluid (as far as we know, it comes with the QS version of fluid). It's used in the Fiesta's dual-clutch tranny. Some have reported better shifting with the fluid but also noticed an increase tranny whine. Others report no change.
Yes, Deysha, the Ford CS Rep, does monitor the site and she has been very helpful.
The best advice I can any of you that are having rough shifting issues is to go through Ford and complain. Maybe the fluid swap will help you. Maybe it won't. One thing for sure, don't mess around with any friction modifiers as Ford has tried this and have determined that it will pose a wear issue down the road.
Many other owners are suffering more acute issues such as, not going into gear, popping out of gears, severe grinding, poor clutch engagement etc. There's a lot of speculation as to the cause or causes of these problems but at this point, we'll have to wait and see what Ford offers up. There seems to be another TSB in the works in the near future. What it will address and when it come out are unknown.
Work with your dealer.

Have you changed the tranny fluid? The manual calls for 3.8L but Tremec says 3.0L is the new refill level and only to use non synthetic ATF fluid. This should eliminate the 1-2 grind

Just curious if anyone else has a 2012 manual car with a build date of March 2011 or later. From what I've read, most of the MT82 transmission problems were caused by improper installation of the pressure plate bolts at the Chinese factory where the transmission is built. Apparently too much loc-tite was applied to the bolts, so they tightened up before they were properly seated and later started backing out after around 1500 - 200 km of driving. I guess this affected a large number of 2011 and some of the early 2012 units, but not the more recent cars. I heard that the more recent units have an updated clutch assembly also, but I don't know if that is actually true.
My car was built on March 28, 2011 and it has no problems at all after 1100 km. I have missed a couple of 2-3 upshifts at high rpm, but that is probably because I wasn't used to the shifter yet. Anyway, many sports cars with high-revving engines produce enough vibration at high rpm to bonk you out of 3rd if you don't hit the gate just right. The list of cars known for balky 2-3 upshifts includes the Mazdaspeed3, Subaru WRX/STI, Corvette Z06, Porsche 996/997 and many more. My old Mazdaspeed3 was hard to shift in cold weather, and my friend who races Porsches tells me that they are a nightmare to shift at anything under -10 C. I think there's a lot of hype over a relatively small number of cars on the US Mustang forums, but I'm still curious to see how my manny tran performs over the rest of the summer. So far, so good and I hope it stays that way.
