What do I do now? MT-82 Woes

[1TUFF_S550]

maybe, maybe not but i did “break in” my stock clutch about 1k miles before any hard shifting. Still stock clutch no issues at all.

I don’t think it’s *all* in clutch break in… I had a grinding issue with my stock clutch, and had the same issue with the McLeod RST.

The only risk with buying a used transmission from unknown sources when it is already out of a vehicle is, you don't know if the internals in it are any good or not... sucks to buy a used trans, spend $$$, the R&R time, and only to then find out it too was a junk trans...

A lot of people are stock without issues. But there’s a lot of people (myself included) that can’t seem to rid their MT82 of grind or lockout.

I could understand the clutch break-in argument *if* the first clutch was improperly broken in, it was replaced and properly broken in, and the issue disappeared.

I could also understand if there was no issue, the clutch was replaced, and the owner started getting grinding.

In my case, I had a grinding issue, replaced the clutch, and still had a grinding issue. Same RPMs, same feel. No different.

I really don’t think poor clutch break-in is causing people’s lockout or grinding issues.

I wasn’t specific, the MT82-D4 is a fresh rebuild from Ford from a reputable forum member. I’m with you on used transmissions though… I wouldn’t want To swap in a trans with an unknown history.

Yes. Some worse than others.

That's not the gearbox then. My money is on the clutch not disengaging completely.

My 2019 would grind/lock out going into third from day one. I suspect someone messed it up on a test drive before I bought it. I replaced the shifter with a Barton Hybrid, and it made no difference on the third gear shifts. I've owned two Mustangs with the MT82 and I hope the next generation comes with a DCT option, but I am afraid the A10 is going to be the only option.

The MT82 is used in many other vehicles as well. You never hear problems with them. Seems to to be only with mustangs. Doubt the car has anything to do with it. Theres a reason why clutches aren't warrantied from any manufacturer unless its grenades or something.

Hmm… interesting point. I’m curious if other vehicles would have the same problems if they were driven hard, or if it’s limited to mustangs. Aside from my BMW or mustang, I’ve never shifted any of my other cars at 6-7k. Might not be a factor… but I’d be curious to know.

It’s not every gear evenly… I do grind a little bit (like synchro nibble) but I only routinely lock out of 3rd. I’ve only locked out of 2nd and 4th once each, never out of 5th or 6th… but I don’t often shift into those at high RPMs. But I get nibble/slight grind on every 1-2 and most 3-4 shifts at high rpm.

A clutch that doesn't disengage completely will affect all gear changes, though not necessarily to the same degree.
The effect is proportional to the engine speed, because at high revs enough unwanted movement can be transferred through the clutch to the input shaft to overcome the synchronizer's ability to slow it down. At lower revs the synchronizer is strong enough to do its job and slow down the input shaft despite the (little) torque that may be transferred to it through the partially disconnected clutch.

If you can upshift normally at lower revs, and most importantly, if you can downshift normally every time, then the synchros are fine.

What other cars use the Getrag MT-82?

What other cars use the Getrag MT-82?

IIRC, certain Land Rovers do. Not sure what others.

My recollection is that the Land Rover Defender used the German-made MT-82 while the MT-82 in the Mustang is made in China. I am not sure I would compare the two.

What manual transmission is Ford putting into the new Ford Bronco?

Nevermind, I see it's the Getrag MTI550 or MT88. I wonder if that's going in the S650 Mustang.

" Getrag promises shift improvements on the new gearbox, partially because it has flipped the design of the MT88 from the typical approach, moving the driven gears to the input shaft rather than the output shaft on the MT82, which reduces the mass that has to be synchronized during shifts."

Transits.. BMW.. Couple more as well.

To the other guy: The QR code on my trans was not made in CHINA. It was made in a Factory in France. Forget the plant name. And, even if some were made in CHINA. They still have to follow strict manufacturing quality control. Just cause there workers are making a 1/4 of American workers wages doesn't mean shit.

Yeah, I wasn't implying that the country of origin was the cause of the MT-82 failures in Mustangs. It's definitely design flaws that are to blame, and they basically admitted that by trying to band-aid the issue on the 2019+ cars by making the shift forks out of cast aluminum. (At least they don't bend any more. They break!) It will be a glorious day when the MT-82 is no longer an option on the Mustang.
