Anyone have experience with a SoCal Ford Dealer that is experienced with SVTs and in this repair?  With 1700 miles, I have grinded from 1 to 2 something like 5-6 times.

The car is newly in SoCal and I want to get the ball started on the fix.  Any update on a TSB?  Extremely protective of this car so want top service and treatment but don't want to grind the gears from 1 to 2 anymore.

Hi all,  Has anyone heard if Ford is doing anything on correcting the 1-2 shift problems on the 2012 Shelby GT500?  Everytime I try to speed shift from 1 to 2 I get a grinding of gears. All the other gears speed shift just fine I have been back to my dealer several times they tell me they can't find a problem.

Just get a MGW shifter and that should solve it. I've drag raced my car and found that if I just concentrate on shifting smoothly (not power/speed shifting) I don't have a problem with the 1 - 2 shift.

Sorry but changing out the shifter is not an option for me.  I just prefer to find a dealer that specializes or has plenty of experience servicing Shelby's and this fix.  It's a fix that Ford needs to correct in my opinion.

My 2012 has done it from day 1.. Went to Amsoil and it shifts a lot smoother but will still grind from 1st to 2nd! The fix will be a new Viper this winter !!!! No luck at the dealer---Ford knows about this but will never do anything about it because of the $$$$ issues..

Mine has ground on a couple occasions. Today with the weather nice.. reading about the new zl1 camaro's mediocre 1/4 mile times I felt like practicing some launches. Drove the car for awhile, everything was warmed up. Didnt grind once, did 4-5 launches even bumped the rev limiter most of them and went right into 2nd. In the past it was much colder out and clearly that made a difference. I will say reading about the shift issue before I bought the car i spent a lot of time putting around 1-2 shifting through the neighborhood. I dunno, maybe that helped.?
I did enjoy seeing those 1st 2nd and 3rd chirp posi patches on the pavement. I know when I see some nice strips from others I always wonder what in the world could melt'em off like that.!

All, I too have had the issue from when my car was new.  I had the dealer replace the tranny.  At the same time they instaled a MGW shifter (which does feel much more solid than the stock shifter), synthetic fluid, and a one-piece aluminum driveshaft.  It all seemed to make a poistive difference.  Recently I installed a WOT BOX just to help protect the trans even more and all I can say is WOW!  I wish I would have done this from the start.  (The two step is pretty cool too )  The shifts are so much better and smooth, not to mention the car is easier to drive.  It is only $200 and any shade-tree person can install it.  You do have to do some cutting and soldering and it will take the better part of a day but when all said and done it is a totally different shifting experience!  I know some people want FORD to solve the problem but it is so much more difficult than that.  Having FORD replace/repair the trans wont fix the inherant problem which is the remote shifter setup.  We will still be bitching about this for years to come.  Do yourself a favor and buy a WOT BOX.  You will then be amused at all the posts about this issue when you realize how better it can be!

WOT box the launch control the car should have came with. Also has the benefit of postive shifting.
WINNING!

Some other people on different forums are now saying its the clutch and shifter assembly. Ford is switching out the 10-12 model clutch with the 2013 clutch. And also replacing the shifter assembly. From what I have read this has seem to have fixed the problem. NOT covering up the problem with a WOT box or a MGW shifter. I am like ShelbyLee in the sense that I paid a pretty penny for this car and I want the issue fixed correctly. FYI the parts #'s CR3Z-7B546(CLUTCH) & AR3Z-7400(SHIFTER)

I read that one guys post on the ford GT500 site. The Part number you posted is the parts that just went into my wifes 2009 GT500 per the TSB for the 2007 - 2009 clutch drag problem.

Have a link?

I just decided to hell with it---this shifting thing is a pain with the grind. Getting a Z06---drop in a Mast cam and then it will be ugly--AND no heat soak here in Texas!! I tried a Ford--have had it for 14 months..

+1 , my buddy just got turned away with his 2012 from a dealership.

Luckily (I guess) mine only does it when its cold. Took a couple grinds to figure that out, but once its warm no issue. I am going to try the amsol fluid change. Hopefully some day Ford will step up and fix the problem. Fluid and or a WOT box is a band-aid not a permanent  solution.

It's a shame a nice car has this glaring issue. Pretty much over shadows all the good things about it.

I brought my 2011 by the dealer twice. He could not get it to grind, so I rapped it up to 6000 rpm and it did NOT grind...both days I was there. He said that he does not see anything wrong with it. I have to say, I"m getting better at driving it. Just a slight hesitation and a hard deliberate shift works. I don't know what it is but I have grinded 2nd gear by shifting very slowly in town, especially around corners. Not sure if it was a lack of concentration on my part or what, but from what I can tell, the clutch is all the way down. Now that I have driven the car for a year, it grinds much less. I think we are SOL unless we get a 2013.

I have a similar problem with my 2010. Grinds more on corners and are sporadic. I have ground it at various RPM's and shifting style (fast/slow). Mine started the grind at about 3K and now I have 8K on it. Seems to be progressively getting worse. Was out the other day with my daughter and out of 20 1-2 shifts, it ground once. My dealer says that when I bring it in and if it does not grind, then there is nothing they can do. He has offered his transmission guy to go for a ride but again if it won't do it on that drive, then I am back to square one. Has FORD or TREMEC ever come out and stated what the root cause is? Was it a material, design, or manufacturing issue or all 3? I have seen a several posts with parts generally replaced. Are these new and improved parts or just new parts of the same design, material etc.

What other forums are you referrging to. I am interested in that I am getting ready to do battle with my dealer if need be and would like more info on replacement of the clutch and shifter assembly with the 2013 model along with fixing my transmission.

I thought the newer GT500 clutches were multi-disc???

Yeah I'd love to have a link too!  I've been waiting patiently to see this get a routine and easy fix process because I'm worried about one-off approaches.  But I'm running out of warranty soon.

[Ecrissman]

I found this video on the net, Sounds like he can get 1-2 shifts without grinding. Probably has to get the tranny warm first

[Boss Hoss 540]

My tranny gets warmer than most folks unless they live further west lol and heat has nothing to do with it. Can have 30 miles on the car in 100 degree temps and it still does it.

Interestingly once my tranny is warm it shift just like the video. You can catch the boost gauge in the corner of the screen. He is into boost at the shift. I guess am lucky I guess. I know one thing if I have been sitting a a cruise in for awhile and someone talks smack. I wont hit the street and run'em.. once cold grrrrrrrind and refuses to go into 2nd. I am doing the Amsoil fluid change.. cant hurt anything maybe a "better" fluid will help when cold.
