LML trans tuning here!

[Harbin_22]

Man you would think people would be excited about this instead of what I see as more bashing. 250 psi is going to help a ton people. For a couple hundred bucks, some guys will be set instead of a full build. I'm sure this will be helpful with a built trans as well. Keep up the hard work Kory! People like you pushing everyday is what the sport needs! Don't let the ignorat drag you down ha-ha

Also- I will happily lower the expected hp amount if enough folks here have the experience of saying "My stock Lml trans broke at 5xxhp, mine broke at 6xxhp" etc.

All I have to go off of for these numbers is the feedback we hear from customers, what I see on my dyno, and what we have tested.

If quite a few LML owners pop in here and say "mine broke at X hp", then I will for sure reconsider what I think this will support for a extended amount of time.

-My Denali went 700hp for a long time with just pressure mods.

-Anthony Piaseki has gone 60+ passes in the mid 12s with pressure mods.

-Burt Reed has gone mid 12s with no trans mods and has been since 2013.

-Brayden laid down 700 back in the day with just pressure mods

-Many customers locally have compound/cp3 conversions on stock trannies still kickin at 600-650.

-John conchado ran his very hard for a long time, I think maybe even 12s on stock trans (could be wrong there)

-John Hevia with his s468/dual pump Lml went s long time.. No pressure mods. He just built his trans, but it was still clickin

And many others I'm sure I could muster up. I'm not saying the transmissions won't break, we know they will.... But all I can go off of for HP estimates is what we have seen and tested. I do know when Many of my trans building friends have told me about building the LML trannies, they state it was obvious the clutches got hot, but most of them were running just fine and had much life left. Now maybe with having the great asset of MikeL here- he can shed some light on what he generally sees of LML transmissions coming in. Maybe he sees more that look like burnt toast than the feedback I have gotten?

I like this forum, very informal forum with lots of combined knowledge. If you guys think and with real experience feel like we should state power numbers lower, then we will. Perhaps more of you with your own personal LMLs can state what failed.

We are not diesel gods, prediction Jesus, or know-it-alls.... We simply go from our testing of many trucks and customer feedback. If we get enough feedback here that varies from our experience, I will happily change the expected support numbers.

Thanks to those of you for the support and positivity of forward movement in the tuning industry.

What Kory is offering is a great upgrade. Like already stated the overall design of the LML trans has a lot to do with why some can survive much better then the earlier Allisons. We all know that it's not a replacement for a built transmission. The factory pressure of the LML was setup with optimum mileage in my mind not what we do with them so keeping the pressure constant instead of dropping out of sight WOT helps big time. Kory has a lot of time into this and just because his data doesn't match up with others doesn't mean it's not what he and the people he was testing with witnessed. I told Kory right off the bat I didn't agree with putting a actual HP rating on the tune for the simple fact of while quite a few have lived for good amount of time making a lot of power results will vary and people will hold him to that number. It's great that we have someone like Kory in the industry who is isn't satisfied with what's available in the tuning world and is pushing everyday to come up with new things that most all of us couldn't even dream of being able to figure out.

I have mercifully beat on my LML on the race tune and its trans is still holding up at 550 rwhp. I'm super impressed with it, I'll get up with you next week Kory and get a trans tune from you. Thanks for the innovation, keep it up...:hug:

Thank you Evan, and thanks for your input as we were coming into release!

Kory do you get both tunes for the $300 or do I have to pick what one I want and if so can you describe both please.

Yes sir just pick one... I actually recommend the race one... If enough people actually report mileage to not change much with the race tcm tune.. I will likely end up dropping the street one.

The street one brings line psi in very fast, but runs low during cruise... but i would really like to see it consistently high. Once i get feedback after mass release, then i will make a decision.

So this is the transgo Jr digital for the LML's?

Ha, something like that! LMAO:hug:

I think probably people will see a greater difference in trans temperatures than fuel economy (on the street vs race TCM tune).

Fuel economy difference IMO is so impossibly hard to measure; I mean hell you would probably subconsciously drive the thing differently (and thus nullify any real data readings/measurements) just based on what mood you're in.

But trans temps, I think you'll see a noticeable difference between the two tunes.

Whether that difference is enough to make the guys who tow heavy in hot/high conditions specifically want to run the street tune and not the race tune is too early to tell....it being winter and all.

I agree with ya! FWIW- When I had your pressure box, it was flipped on while i towed heavy stuff all the time and never had a problem.. It was around 10-20* higher... Never really seen above 210 though.

 

[Mike L.]

Stop and go driving is where I saw the highest temps with main mod disconnected. There is no air flow to the cooler below 35 mph.

I had a bet with someone once that we couldn't put our rental car (A charger) into limp mode. I did stop and go for 20 mins.. Literally on and off throttle. She limped and threw a trans light

Anyone tried Kory's LML trans tuning yet and have any feedback?

 

[THEFERMANATOR]

Just curious, but does the pressure control for the lml's work as an on off, or can it be varied like other gm transmissions? Would be nice to use a variable pressure control where it only goes to kill at say half throttle and up, then vary it at say 150-200 from 1/4-1/2, and run stock below 1/4. This to me would seem to be best for the trans ascwell as maintain the best cooler circuit flow.

Yes sir, that's how my "street" file works... It increases line to basically double of what is stock, except for idle/cruise. Those are stock.

So cruise and it has stock line, tip in 30% throttle and it'll have near double of stock... Go 60%+ and its 3x+ more than stock.

Most people just ordered the race trans setting and it just call for max line all the time. On DF, quite a few are giving feedback or 10-30* increase in trans temps, former shifts (that get mostly smooth), relearning necessary... But driving smooths it out to.

So far so good! We had one in house recently that had a little shutter as it has been running at 600+ for a while... With the line psi it quit shuttering, however, I'm sure it's on borrowed time!

Just the feedback we have so far... But have sent out MANY since release and currently no issues or bricked TCMs, so that's nice. Lol
