hi all does anyone know if possible or where to get automatic adjusted so doesnt go to 5th gear at 60kms an hour rather 70kms? I often use tiptronic mode because of this and run LPG not so worried about economy.

Gear change points are coded into the TCU. Easiest to keep using tippy.
That's what it is for.

On the 4 speed, minimum speed for top gear is 55 KPH. Around town, you get lots of 3 to 4 back to 3 changes, if I'm driving my TL I always use tippy to stay in 3rd if the speed changes often.

On both the 4 and 5 speed, top gear is set to be used at 60 KPH for economy testing. With tippy, you have a choice.

Mitsubishi deliberately programmed the 380 auto to change to 5th at 40kph. In my KW Verada GTVi AWD, I used tippy all the time and changed to 5th at just over 40kph. Wish I could do that to my NX Pajero as it won't shift to 5th until almost 60kph. This is annoying considering how much extra torque it has over the Verada and 380 and it has a much stronger AISIN auto.

IMO 5th at 40 or 50 for that point is silly. I prefer 5th, being an overdrive only to be there at 80 or above

You come to hills, need to speed up and all you are doing is loading up the engine

I agree should have been overdrive 80 or above. mine revs drop even more at 70 maybe converter lock up mode if exist on auto. I wish bought manual will have to keep driving in tippy. I use tippy but sometimes forget when take off from light till hear lots of revs. lol
