Manual Trans Concerns

So a few days ago I upgraded from 227AT for a 302MT. Now I know how to operate a MT and I've driven plenty of manual cars in my time but only other people's so the sounds and noises they made, I didn't even bother paying attention to, you know? Not my car, not my problem, right? Well this is my first manual car I've ever owned so now its my car, my potential problems. Its a used 2014 base GT with 27k mikes. Bone stock.

Concern #1. When shifting from 1st to 2nd at about 12-15mph, as I press the clutch, I hear a "clunk". Doesn't happen every time and I thought it was from me not letting off the throttle enough but it just randomly does it.

Concern #2. While normal driving around in either 4th, 5th or 6th gear, when I let off the throttle, the car jerks a little, like it trips over itself. But when I roll back on throttle, a noise from the back is present, as if something is engaging. Its a "clunk" as well. Never had this happen in my V6 auto.

Concern #3. Just running through the gears, why is it so resistant? I've driven cars where it takes barely any effort to shift, but this is like you have to force it over a lip!

Now should I be concerned or is it just normal and harmless, or do I just need more practice to get used to my car?

Thanks!

First problem could be the driveline clunk. And the mt82 is known for concern 3. Not sure what the best solution is now as there seems to be a better one every 6 months

People have swapped out the bracket and shifter itself with good results. Google around and read a bit and try to figure out if you are fine with the way it is or if you want it to be better.

Yeah, the clunk is the two piece drive shaft. Mine does it all the time. MGW Race spec shifter is a common mod to help with #3.

Not quite sure about #2...

my guess is drive shaft for 1 & 2.....and I wonder if you ended up with a short throw shifter. My MGW takes effort compared to stock. Do you have someone local to try theirs? I see several folks from TX on this forum...put out a request offer to buy lunch.

Change the transmission fluids, get Barton shifter with 2 post bracket or MGW. Those 2 really help on the shifts.

As long as you understand it's never going to be perfect, you can swap some things and make the MT82 work well. Biggest difference for me was made by the fluid swap to Amsoil MTF. That combined with the MGW Race Spec cleaned things up a lot. The braided clutch line and Whiteline trans insert helped too. Still, have to skip 2nd when cold and the occasional tough shift when getting on it.

Agreed on the clunk, sounds like the drive shaft. Mine does it too, but rarley.

Thanks for all the advice, I had a feeling it was all nothing to be too worried about but this is the car I've been wanting since it debuted in 2010 and now that I finally have one I want to make it last.

Everyone has pretty much covered your issues so I'll just add my own observations.
My car is lowered with after market LCA's/UCA and have replaced the carrier bushing with Urethane.....from the stock OE rubber, and used the Whiteline tranmission mount spacer along with the CE Urethane bushing for the shifter.
When I bought the car with 2700 miles and it was bone stock it did clunk like #1 and #2...........once I changed all of the suspension it did it worse. I took the two piece drive line out and put a one piece drive line and I very rarely have any clunking.............basically gone.
Just recently I changed to the Iso-Clutch Reservoir which splits the hydraulic clutch from the brake master cylinder..................I have noticed a real difference in the feel of the clutch and I don't have a braided clutch line. Before I changed it the clutch at times would have almost no feel and when I was carving corners it got worse...............as I used more brakes.
When I installed the transmission mount spacer and CE bushing the stock shifter really had a totally different feel.............200% better than it did stock.
Personally I think Ford should have used a one piece drive line and separated the clutch/brake fluid................IMHO

it is a fussy transmission....always pay attention to shifts don't be lazy with it. For my V6 the biggest help were motor mounts. enjoy the ride

I've found that you really need to invest some work into the MT82 to make it not terrible. I did a blowfish bracket, whiteline trans mount, fluid swap, braided clutch line, and an MGW shifter. Mine swaps gears with little to no hesitation at this point. I do hear some noise occasionally (mostly a bit of whine?) but it's hard to discern over the exhaust and other driveline noises.

+1 for some of your issue sounding like normal noise coming from the driveshaft. A one piece might solve that, might not. Either way, you reduce weight and free up some wheel horsepower.

It just amazes me that Ford built such a fantastic car in the Mustang and put such a poor manual trans. in it. On the other hand their 6R80 automatic is one of the toughest and best trannys out there no matter what car company you're talking about.

I have never had a better manual transmission than the mt-82. Some people want to hate on it but once you give the shifter some love (which I would do to ANY manual trans) it's great.

I will say that the gearing the MT82 has is perfect with the 3.73's and having 5th gear as 1:1 couldn't be any better.

I drove many different manuals throughout my life also, and I too was concerned with how much noise my car makes. I got a great deal from a private party on my car and was starting to think the transmission was messed up, and that's why the guy was selling it.

I was relieved to find out that everyone hears the same type of noises and that the manual is just noisy. The "clunk" when pushing the clutch in at low speed is annoying, and the 2 - 3 shift is a pain sometimes. I'm thinking of trying a Barton two-post bracket to clean it up.

28" tire with 8,000 red line. I can still use it. With a good drag radial. Best ones I have used yet are the ones from M&H.(they are built like a slick vs normal radial ) 780 ft/lbs tq = stick like glue. Tires only last about 200 miles though if that

1st gear is great on my 3.31 gears and I love the 5th 1:1 and 6th .6 overdrive.
I also get all the same issues as the OP and know that is the way it is for the reasons the others posted. I don't every drive it in snow and its garaged so I don't get the sticky when cold issues.

I found the best solution was to first pay attention and it gets better. I do plan to get a bracket for the shifter, I don't want a short toss shifter as I dont drag race, just street drive it.

Edit: I also went from a 227AT to the 302MT82

All of you with 3.73's...................I love my first gear and although the 285/35/20's do spin they do hook and when I shift into 2nd even with the car lowered it will bring the nose up....................and I can putt around town in 4th at 35mph.................I had a Tremec T56 in my 97 with 3.73's and it wasn't as easy to drive as the MT82...................with 4.10's the T56 feels more like the MT82 with 3.73's.

There is a TB on loose fly wheel bolts. That could be the issue.

There's no way this is the 2011 TSB situation. That was solved for the '12 MY.

The clunk noise in the clutch can also be the throw out bearing or a little too much end play in the shafts internally. It isn't necessarily the DS. My car makes some of these occasionally and generally, I can drive around the noises with smooth, positive use of the shifter.

My experience was that a bearing failed internally very early in the life of this trans, Ford fixed it and I have some of these new noises now. However, I have fired the car down the track over 100 times on slicks, with drop clutch launches and nothing's broken and no noises have altered or got worse.

I have the stock shifter with a Modern Billet knob, whiteline trans bushing, the Steeda shifter bracket and the MGW torque arm bushing. All these things made a difference. The most significant were the Steeda shifter bracket and the Modern Billet knob.
