Going to try TCM tuning
- Thread starter pavetim
- Start date
If you wanna mess with shift points go for it which not sure why you would, but if you don't know how to read and understand the TCC tables leave them alone.
Why fix what's not broke?
Because there is a lot to be gained.....

Well I think the later gears like 4,5 are too close and the tcc locks up with too little throttle input. But I just got my tune and exhaust installed so I will let it learn a bit. Just need to remember, i changed my lmm a little and had it perfect but don't remember exactly what i did lol.
LML trucks are no where near what the previous versions are. They have limitations and you need to know what you are doing when tuning them. With the tranny I can guarantee you that it will not work like you want it to. You only have direct control over certain items and the rest are just values that don't respond to your input the way you would think.

You're correct on the first part, but not so much on the second part.
Coming off the line you are in TQ multiplication mode which gets the weight moving and yes it makes heat. It is very necessary. Right after that the converter needs to get into coupling mode ( getting as efficient as it can ). At this point the converter should be trying to get to 1.1, but it never will without TCC.
All of the above should start with the proper converter for your particular setup and then fine tuned for your purpose.
I don't mean to threadjack but. I have a 2013 that I am scheduling to get the trans built with an R convertor. I currently have PPEI TCM tuning and am wondering whether I should go back to a stock file with the built trans or just have them send a new tune without the line pressure adjustment. I guess my question is, is trans tuning worth it on an LML if you have a built trans and well matched converter? The truck is still stock turbo with no real plans other than fun responsive daily driver and it currently sits on 35s with 4" lift and stock gears.
Search this site, that has been covered many many times.
the LML converter is a better converter than years prior, that said i would still use converter lock up when cruising around and light throttle input. your mileage will be best with it in lock up and keep trans temp the coolest.
i drive at about 50mph around town. at 50mph in 5th gear TC locked, i can light my turbo decently but the truck will smoke. i moved my TCC lock up to 55mph so i could light the turbo off lightening quick and no smoke. My converter is also extremely efficient (ML-G converter) so unlocked, i dont blow through it easy even at the power im at and it does very well trying to get to that 1:1 ratio like Mike was talking about.
if you mess with it, make little changes and drive it for a while to see how you like it. dont make big changes.
