2nd gear syncro’s I think. I didn’t notice any difference with the Stage 2. Then what makes me think their work is shoddy is when I told them I wanted them to tap a hole for my Transmision sensor. When I put trans in my temp gauge did not register. Pulled sensor and this was what I found. I would not trust their work.View attachment 82124

The sensor has RTV sealant all over it. It screams to me that no care was exercised during installation. That has to have a negative impact on the sensor.

@MajHazard, Amp Distributors sells hardened stronger gears and a 26 spline input shaft for the 15-17 MT82. I believe they also sell billet aluminum shift forks for those years too. That’s who I bought my billet shift forks from for my MT82-D4. Aside from that, SynchroTech sells carbon synchros for the MT82 and The MT82-D4.

Can you elaborate a little more on exactly what the conditions were when your 4th gear went? I’ve read more than a few horror stories about customers with failures, including this guy in the video below. I also talked to Calimer on the phone about buying a set of the billet gears that they use in their Stage 3 builds and they said they wouldn’t sell them unless they were building the tranny for a customer. I then asked if they knew where I could get some OEM gears and was told I’d have to get them from the dealer, but everything was on back order and that’s why they buy used transmissions to get parts for their builds.

My problems with the Calimer stage 2 are well documented in various threads. You can use the search functions and read all about instead of rehashing it here.

Did your Stage 2 have Cryo treated gears? Was it the heat that caused the gear to break apart? I’m just curious and trying to understand what the limits might be for my tranny which has everything Cryo’d (gears and shafts) and an external fluid pump to help keep the gears at the front of the tranny lubricated under heavy acceleration. The spray pattern from the two fittings are directed at 4th gear.

The stage 2 was supposed to be cryo treated and rem polished. I did not disassemble it myself, so I can not be sure it actually was. I do know that from tear down to back on a truck to me was only a couple of days which is awful quick to have sent my gear set out for metal finishing. My guess is they put a gear set in they had instead of sending mine out and reinstalling it which would explain why 4th broke. My trans had no damage when it was sent to them with a little over 92k miles. No drag launches and Redline MTL fluid changed annually starting at 35k miles. It was out for a clutch rebuild and I sent it in due to the mileage as a preventative measure. I wish I would have just reinstalled it and ran it until it broke. I am sure it would have gone more than 1,100 more miles.

I just found and joined this forum, which looks great to me!!! I've been doing trackdays with my 2015 FT PP for 6 years. This summer the 6th gear Syncrho went out. Was going to send to Calimer but have seen a lot of issues and quality concerns posted.

I also looked at updating to the Tremec Magnum XL but I don't like the ratio mix they have and 3160 are hard to find. So I'm working on what to do with my MT-82. I found a remanfacturing business near by that sounds like they has a good quality control process, but only rebuilds to factory specs and parts. I found another shop that said they would rebuild with a Carbon Fiber or any kit & parts. That's how I ended up here, looking for a kit.

So I"m stuck with do I go back to OEM with the reman place that as good quality control or go with another good local shop that will build with a kit I provide? And what kit would that be?
My transmission has lasted me a long time... I usually avoid mid summer trackdays to avoid some of the heat and only do about 4 a year.

This my spreadsheet I used that shows I would be doing 2, 3 shifts most of the time with a Magnum XL:

The gear ratios are definitely different. The XL close ratio gears 1-4 are basically equivalent to gears 2-5 in the MT82. First gear in the MT82 is pretty useless. The 2-3 shift is not as convenient as the 3-4 shift in the MT82. I wasn't entirely happy with the MT82 and my 3.55 rear either. I am going to swap the ring and pinion to a 4.10 when I replace the TracLoc with an Eaton TrueTrack this winter.

This seems like the appropriate place to add all of the information that I’ve learned and/or am still learning about my MT82-D4. While normal,street driving and drag racing occasionally are more my cup of tea, I do think others with the MT82 can still benefit from this info. Let me preface this by saying, I am no expert on this transmission, I’m just a guy trying to improve upon a known weak link. I hope I’m not violating any rules by posting an external link in this thread. With that being said, here’s my rebuild link from M6G with lots of pics. If anyone sees anything that I’m doing wrong or need to do differently or reconsider, please let me know.

I got two bad ones from Calimer.
If you buy from them, good luck!

Its luck of the draw really, I have imported about 5 calimers to Chile and they worked out pretty well.

The sensor has pipe threads and they tapped regular threads or cross threaded it. Notice the washer they used as the sensor was screwed in all the way. That’s not silicone it’s a epoxy or JB weld so they could repair the messed up threads. They said it was to prevent leaks lol. After making a plate and tapping and securing it to Transmision and buying new sensor they sent me 3 quarts of Amsoil lol
I have no idea why they paint the transmission case but by the time I got it home paint was flacking off

This is a great thread! Thanks for sharing!

For something that is billed as the world's strongest MT82's it shouldn't be luck of the draw. There are too many of us that have had bad experiences with Calimer built transmissions. There are obviously some quality issues.

Very much looking forward to having more options!! I was hoping that the XL was the answer, but even then the best bet would be a race version (dog gears and faceplated), which means a approx $8000 conversion.

@S550AZ is the only person I’ve seen that has it. Wondering the same because this may be the way I go depending on feedback.

Having options is one of the reasons that I swapped to the T56 Magnum XL. There are more places that work on them and parts are more readily available. You can also buy a brand new one for about the same $ as a Calimer Stage 3 using your transmission. The Magnum XL is rated for 700lb/ft of torque and 7500 rpm shifts which covers most of us unless you are Fabman..

 

[misterpeanut]

I was thinking it'd be cool to buy parts and rebuild mine, but after reading NG0T8R's thread about his rebuild (which looks to be going very well, but extremely involved), I think I'll just ship mine off to have it rebuilt by guys who do it.

The Magnum is the answer...as long as you don't try to shift it at 8200 rpm.
Stay around 7600-7800 rpm and you will be fine....have I steered you wrong yet?

Happy to stress test all the new parts for everybody....I'm getting pretty good at it. LOL.

No, I am a faithful but broke disciple. My rev limiter is set a 7950 Though, so maybe I can bring it down a bit If my Xmas stocking is stuffed with cash.
