19 mt82 Lost 3rd gear and reverse?

[silverbullet85]

19 mt gt. Specs are prochager stg 2 lund tuned on 91, xpipe standard 4.75 pulley, car has 12,500 miles on it. I drive it fairly normally but I do get on it now and then.

Ok heres what happened, about a week ago I took my friend for a drive and on the highway the car wouldn't go into 3rd gear untill the 4th try, never had that happen before and didn't happen again the next 5 times I drove it,, untill today. Today on the highway i went to downshift to 3rd gear and the car just went into neutral. I tried a few more times the shifter felt fine but 3rd gear was gone. I checked all other forward gears while on my way back home and they were all fine. If I'm at a stop and put it in 3rd and start letting off the clutch then as the clutch is almost all the way out it makes a grinding noise. I went to park it and found out reverse doesn't work either and whats odd is that the backup camera won't activate either. I haven't been able to find any threads where someone lost one forward gear and also reverse.

Man that sure sucks! I thought the 2019 MT-82 had the upgraded steel shift forks? Please keep us posted on the fix and try and get detailed pics of the carnage if possible, so that the rest of us with the 2019+ trans will know what to watch out for.

He probably broke third gear itself, and the pieces that broke off are jammed in the teeth of reverse. Not common, but not unheard of. When you're boosted, it's much more likely that these units will break.

I'm not sure if it is the shift forks, when they go it seems like people loose 2 gears, so if it happens in 3rd they loose 3 and 4. I lost 3rd and never knew it happened untill it was gone, then I found out reverse is gone. I have never seen another post that someone lost reverse as well as a foreword gear.

 

[silverbullet85]

It did this thing where the gear lever refused to go into 3rd so instead of forcing it i just clutched in and out and then it would go in but just pop back out and grind. It did that a week ago one time and never had any hiccup and I drove it a bit since then. I'm definitely harder on 2nd gear and only occasionally go into 3rd at wot. I've hat 2 other mt82 boosted s550s with 30k miles and no trans issues at all, never even wore the stock clutch out on my other cars

That would be worse case scenario
Going to call Ben calimer on Tuesday and see what they say. I wonder why the backup camera isn't working, you'd think if the gear was jammed the camera would still activate. It feels like it goes in reverse but it just goes to first

I didn‘t think Calimer was working on the MT-82 D4 trans, only earlier models. Has that changed?

I just installed a 150 hp shot of micro us on my FBO 2019 Bullitt and this concerns me. To run the fastest 1/4 mile et, one must shift as quickly as possible and spin the motor high. Unfortunately, it doesn’t seem as if this trans will allow that without a high risk of damaging it.

Have you verified your lockout collar isn't broken? On the D4 I think the unit has to physically enter the reverse gate to pull up the backup camera, so if it's jammed with debris that won't happen.

 

[silverbullet85]

Its not broken as far as I can tell. It worked fine an hour before all this, once I lost 3rd gear I lost reverse. It feels like its going in reverse, the collar comes up fine and I go into what I think is reverse, but its first. It definitely is related to losing 3rd just never been able to find a similar situation

I mean people run way more hp for way longer and don't have issues. I think its just my luck where things that shouldn't break this soon do. And I believe lethal performance advertised them selling the mt82 d4. I'm going to send mine in either way so looks like car will be down for a while. Don't even have a place to pull it apart going to have to figure some shit out. Definitely glad I have another car

It does, but the problem is they're only held by 4 tack welds. Full welds would absolutely get rid of any fork issues. And if somebody does that, might as well replace all plastic parts, which would make the transmission much more robust IMO, for those 'abusing' it with higher power.

You'd be asking for trouble indeed. Our tranny is not fragile, but not robust either, so it can't be abused too much, even in stock form. Add 30% (or more) power, and you can't expect not to have issues, especially if you're going to subject it to quick shifts... which it doesn't like. Since you'd have to open it up to beef up the forks, and replace plastic parts, many folks roll the dice, and do that when it eventually craps out. But you can't blame the tranny when it fails with so much more power than stock.

I 100% agree with everything you said. I don’t plan to shift it as quickly as I am capable of. I’ve actually been training myself mentally to make slower shifts whenever I drive the car. As for the power increase, I’m not sure what the limit is for this tranny, but there are reportedly, more than a few people making the kind of power that I’ll be making on nitrous, who have either been very lucky, or simply gotten very good transmissions. I don’t like it when things break, but do understand that racing or even spirited driving can eventually lead to damaged parts. It’s a risk that I’m wilying to take to have the car perform the way that I want it to. If goes, I will upgrade it. I May even upgrade it whenever it’s time for a new clutch since I’ll have to remove it.

It doesn’t seem like it takes a whole lot to damage an MT-82 D4 though. Here’s one example of how easy it was that was caught on video. To cut right to the chase, got to 7.26 min to see the break occur.



This next video has good information on what’s causing high rpm lockout, which can lead to forced shifts and broken shift forks. It also contains info on using the factory launch control vs slipping the clutch.

I have a 22 GT with 6speed and all the extras (shifter, mounts, line, etc)and at low mileage I broke 3-4th shift fork

Did this happen on a high speed shift attempt with lockout? Are you going to have it repaired under warranty or will you be upgrading via aftermarket components?

 

[AZlb5.0]

Why not upgrade to a T56? I mean if you’re going to pull it minus well go with something that will hold more torque and abuse. For about 7K you can get the trans conversion kit and other goodies. That’s the route I’m going to go once I start making real power on the Mustang.
