Hello All, First I would like to thank everyone in advance for the help, as well as the administration team of this forum for allowing me to be a member. I would like to apologize in advance for any typos and/or errors, English is not my first language but hopefully between friends and google translate, I should minimize the issue LOL. I am going to give as much information as possible so my post might be lengthy. With that said, I recently bought a 2011 GT500 with 39,000 miles on it and love the car for the most part. The car now has 44,500 miles on it and I am encountering transmission problems and I am looking for a solution. I researched around and within this forum and could not seem to find an article, or thread with the issue I am having, therefore I decided to create a new thread. I apologize if there is a thread on this already, and I failed to find it in my search. I am not a mechanic but I love to learn as much as I can, specially about this matter. I have done oil changes, changed a radiator before and small jobs similar in complexity, so not much compared to some of you guys. My problem unlike most people is with 5th gear, 6th gear and reverse. I have seen most people complaint about the shift from 1st to 2nd gear which I am unsure if its present in my vehicle, as most people experience this issue when shifting at high RPMS and I have not shifted from 1st to 2nd pasted 3 or 4 RPM. The issue is that the car will not go into 5th gear, 6th gear or reverse on certain occasions which I will explain in more depth below: 1st time it happened – drove from work to the airport (about 30 minute drive), did not drive the car like a princess but was not redlining the gears either. Once I get to the airport, I went around 2 times to pick up my passenger, and as I leave the airport when I get on going go thru the gears, when I get to 4th gear and try to go from 4th to 5th it would not let me at all, almost like something blocking it. I went back to 4th and tried it again, same results, so then I tried going from 4th and neutral to 6th with same results. The issue lasted about 10minutes and then it started going in 5th and 6th gear like nothing happened. 2nd time it happened – I drove from my house to cars and coffee meet (about 30 minute drive) drove normal and when I went inside the parking lot, I found a spot and went to park in reverse and it would not go in reverse, same feeling as what happened on my way to the airport. Took my car to a specialized shop on Mustangs, they called me after a couple of days and tell me they are not able to replicate the issue. I told them my two scenarios pointing out that it did not happen in a 5 or 10 minute drive, so they said they will drive the car some more. Got a called a few days after and they said the same thing, they drove it some more and were not able to replicate the problem. I asked them what was their recommendations and they said to change the shifter for an MGW one. Bought the shifter and got it installed and which did not solve the problem. 3rd time it happened – Wake up on a Saturday, go turn on the car and reverse would not go in, however, after a couple of tries it did go in. 4th time it happened – Went on a different Saturday to the gym and then for a drive of maybe 20 minutes or so, and it would not go in 5th gear, tried it 2 times with no success, then tried 6th gear and it went in and after that it was all fine. I checked the transmission fluid and is good and changed the shifter. I hear the Syncros on this transmission are not the greatest, so I hear about Hybrid Syncros (part carbon fiber, part metal/steele/brass) that might solve the problem everybody else is experiencing from 1st to 2nd gear but not sure. Also, with reverse being in the mix, I don’t even know if reverse has a Syncro, as well as I am not a mechanic so can work on it myself, I would have to paying a shop which from what I understand, it would be at least $2,500 to change the Syncros. This brings me to question that is, if is the Syncros and it cost that much money to fix, is it better to get a new transmission? If so, what transmission? Certainly don’t feel like gambling with the TR6060. By the way, to the best of my knowledge the car is stock except for borla exhaust.
