My 2018 GT isn't new anymore so stuff is bound to feel and act differently over time. Little while back went on a road trip across Germany with many autobahn miles, and I paid for all the gears and revs so used all of them often.

After a few hours I noticed especially in 6th @130-140mph that 6th gear just wasn't giving me any power, was very slowly creeping the last few hunderd revs, manually shifted to 7th and could notice a increase in power. Always monitor the temp of the trans and was as normal as ever, just slightly over the top position, at the time I figured it might be heat soak from the many miles of pushing it. Could really feel it across the whole center console.

The other day I drove away from 1st not WOT but was kinda pushing it, I noticed in 2th it just wasn't pushing at all and it quickly shifted to 3th, didn't notice any wheel spin so doubt it was just an early upshift. The whole car was lunging a lot as well, when shifting between 1st and 2nd (my engine mounts hate me I guess), dunno if it can limit power based on condition like that.

It's 2018 with 28k miles, not really sure if I am looking at a problem here or if I should take it to the mechanics or know what to tell them. Apart from this it shifts like a dream still, normal driving it's smooth and steady (recently reset learning tables helped with some harsh downshifting).

I read about countless of issues not sure if anyone could say if it's anything related to possible issues? guess the least I can ask for is new oil on the next service, should be about time I guess.

Have the fluid level in the trans checked. Those A10s are known to come from the factory with low transmission fluid
