My trans SUCKS.
Before next summer it will be a lawn ornament.

 

My MT82 will shift 1st to 2nd fine, if I ride the clutch and let the clutch slip. If I am not letting it slip, it will engage very fast (typical of a Ford clutch) and my car will begin to buck from the sudden engine torque jolting the drivetrain.

From 2nd to 3rd, I notice the same thing the OP experiences. I have to jam it into 3rd gear position pretty hard sometimes. Luckily, I have not gotten any grind from doing so, but it seem like it's hard to get into 3rd, as if I am not stepping on the clutch and I am locked out.

Since I have never heard of the MT82 before, it could be a 1st year growing pain. But I am seeing mixed problems all over the net. Some people have some problems, and my problems with mine are not 100% the same as other people with MT82's.

Ford should have just stuck with Tremec and asked them to upgrade the T3650 or put in a T56 into the 2011 GT's.

 

Yep, same here. Started around 4k, and I'm almost to 5k now. 1st to 2nd can be pretty bad. It gets better as it warms up, but isn't always perfect once up to temp. Strangest thing is it is buttery smooth for me if I'm at WOT and doing high RPM shifts.

I've considered a fluid changes as others mentioned, but the thing is brand new. I haven't taken it in yet, as I figure I'd get the same BS response as you did.

 

Update on my 5th gear grinding. Shop was able to replicate the grinding issue and then contacted Ford...they were instructed to remove and repair the transmission. I was hoping they would just replace it with a new one. I'm sure they will eventually get it right.
This is my first major issue with a new car...frustrating!!!

 

I have the bad first to second shift. Told by Ford mechanic that it is because of the skip shift feature. We should try to eliminate it and see what happens. I'm calling Brenspeed tomorrow to finally get that feature eliminated.

 

Question, if it is the clutch, why do the trannies feel notchy when rowing through the gears with the car off. Shouldn't it be buttery smooth. Try going through your gears with the car off. I think you can replicate the feeling a lot of people are getting. Sometimes its smooth, sometimes not. Just seems to be how the sychros line up. If your shifting with the car off and its smooth OR notchie, try rocking the car a little and try again. I bet it feels different. I think its just the way the tranny feels, not the clutch. However, I guess this is a different issue from those with bad pedal assemblies or sheared clutch alignment pins/backed out bolts Its notchie, just like every other performance car I've owned (90 GT 5.0, 95 5.0 GT, 05 SRT4).

 

Seems to be the most recent thread on the issue....so instead of starting my own.

It's been about 30 degrees here in the morning, and the shifts to 2nd, 3rd, and 4th have been unusually "toothy".

2nd will grind, 3rd and 4th are very rough.

Apparently the new Mustangs don't like the cold. Pony need a blanket?

Any updates from the people that have approached dealers yet? I have a dealer that I think will work with me, but sometimes knowing what to say before going in is best.

 

The car's adaptive learning will actually eventually allow you to shift into 2nd gear even under skipshift conditions. At least that is my thought. I now have no resistance whatsoever even in skipshift conditions.

However, I do notice resistance when shifting to 2nd and sometimes even third even when NOT in skipshift conditions.

 

Cold Minnesota winter coming, putting the 5.0 in hibernation for the winter. 1st -> 2nd gear rough shifts are definitely more noticeable when outside temp is in the 20's but seem to improve as things 'warm up'. Let's keep an eye on this as a group and inform the service centers of this concern.

 

The T6060 that was in my Challenger was crazy notchy when cold. This seems to be about half of what the RT was. Although I haven't put a 1000 kms on it yet and will be stored for winter I'm confident that it's due to it being a more robust trany compared to a less HO car like the V6 stang. The T6060 was noted in the owners manual that it would whine some in normal conditions and be stiff/notchy in cold and not to worry as this was do to the high performance aspect of it.
