I think it you keep on beating on it though it will get to the point where it has to be disassembled to be repaired. Then it's time for a few gear changes and better synchros.
2012 GT500 2nd Gear Grinding Issues
- Thread starter redirocrt92

The WOTBox is a great feature to have, but you're going to blow your tires off under full acceleration. You have to mat the accelerator to get it to engage the ignition cutoff. I might have read somewhere where you can play with the voltage and get it to engage earlier.
I have found the best use for the WOTBox is 2nd gear and above and to use the 2-step to scare people crossing the street, LOL
I also have the MGW shifter and the fluid change. Of everything, I found the fluid change AND some miles to be the most effective. Oh, and I already had Ford go through it (helped some...). Everything you can do to firm up the shift and reduce friction inside the box is going to help. The car twists and torques too much to get a clean remote shift telecast to it in real-time. Firm motor mounts will help, as will engine limiters (to the subframe)...but those have their own drawbacks on the street, mostly NVH related.

One Gallon/4 quarts
You will have a little left over, as factory fill is 3.6 quarts or so.

Anyone tried these that can report back? I have read that they did eliminate the grinding issue but I cannot find that info now.

You mean you didn't save up for one of these yet? I have one already! :thumbsup:
I know a few guys with the infamous MT-82 Getrag that has used these to assist with fast shifts and eliminate grinding. That was in combination with better shifter parts and superior fluid.

Thanks a lot for the info, My car did that just ONE time from 1 to 2 and I was like '' OMG my brand new car :idea:... I'll change that this summer.
I have heard of this but I have not had a issue as of yet. Funny though, my dealer did say it was a T.S.B or whatever its called on this issue and for the 11's they were changing the oil, and also removing some of the rubber bushing on the stock shifter.
I had a 2011 Shelby with the dreaded 1-2 grind, Ford repaired the transmission ($4000+) and the problem was never solved. I had the same problem in my 08Z which has the same tr6060 transmission. I got frustrated with my Shelby and sold it after only owning it for 2,000 miles.
just my 2cents. spoke with tremec rep and the finger pointing is now back to ford design with some type of restriction in the clutch release hydraulics which slows down the action even though its full pedal up or down. he could not elaborate any further. also admits the camaro has the same problem. sounds like the throw out bearing just isnt moving fast enough to me but supposedly they solved that with a special lube on the splines. grabber on TS does have a good thread on this.
about 10-12 years ago, the 98-02 Camaro and Firebird (Trans Am) were having shifting issues. One of the remedies was to remove the braided hydraulic line, use a 1/8" drill bit, and enlarge a built in restricter plug slowing down the flow of fluid. We called it the drill mod.

My best advice is to visit allfords.....Contact Deysha....And you will see movement on this issue. I can confirm this is a real issue and one that plain shoudn't be in a $50K car:mj:..This is NOT just a case of.... "these fools ain't pressing the pedal all the way to the floor".....or...."these guys don't know how to shift"...... like i was first told when reporting the problem...
In the end I was with out my car for 20+ days but when i finally got it back it was right.

What was the final fix?
I have a 2010 with the same issue. installed the the mgw, wot box, and tried some Royal Purple max atf. still get a grind when trying a 6k+ quick 1-2 shift.... going to switch to amsoil this summer to see if it helps. out of 3, the mgw helped the most.

I've probably posted in all those links above. I had the grind with a brand new 2012. Final fix was having ford rebuild the tranny and replace 1st and 2nd gears and syncros. Read the GT500.com 1-2 shift grind thread. Find "Deysha", she's the Ford corporate customer service rep- PM her your VIN number and local dealership info. She'll escalate your case to a very high priority and talk to your service manager. Watch the dealership JUMP when "corporate" calls and is personally involved.
Tips:
1) Go on the test drive with your dealer's service person- tell 'em to shift from 1-2 at least above 5500rpms like they're trying to spin/chirp/catch second. GRIIIIIND.
2) Keep the car until they get in all the parts and specialized tools. There are four tools required for the tranny overhaul that dealerships don't normally have. My dealer had to get a set shipped in.
3) Once they have all the stuff took 3 days to get it back. Now it's fixed.
I don't recommend going to the MGW shifter unti after warranty work is completed. If you have the grind, then put in an aftermarket shifter- they can completely void your tranny warranty and your SOL.

Sorry....The dealer rebuilt the tranny with all the parts listed in this thread:

I started a thread asking if anybody was running an after market clutch line like JHR I had on my 5.0, but nobody has responded and just wondering if it would help?
