Issues with computer/trans 2012

New to the forum.

Got my 2012 JK and put some 35s on it, week goes by and my ABS/ESP lights come on and stay on. Well, I didn't think anything of it because I didn't know that was an issue because I'm an idiot. Traded for a set of 33s and issue persists. My problems so far consist of:

1) ABS/ESP lights stay on all times while vehicle is on
2) (randomly) gets into a weird mood where the transmission (auto) won't shift until 5-7k RPM and will shift then stay at 4.5k and erupt a God awful sound.

I got an alignment and ran it for a code. I got -d0ne- which was a relief but at the same time a worry because now I don't know why is the issue. I have been told a sensor of different sorts but wouldn't I have gotten a code from it? I've been advised to use a programmer and let the computer know I have 33s but will that resolve it? Not sure what to do at this point and being a broke college student who lucked out on a few tire trades isn't helping.

Thank you a lol for your help in advance!

Yes a programmer recalibrating the tire size should fix your issues. Currently it is reading a different speed then what the vehicle is expecting to see for a given RPM range and the computer does not know how to translate what it is seeing other then telling you it is having an issue.

Thank you so much. You just really helped me. Is there a specific programmer you would suggest? I don't want to spend a ton of money but you have to pay to play I suppose

Procal is easy to use and almost fuck up proof.
It has no screens or bling, it just works.
The others can monitor and change various settings and also obd2 data. I think for the most basic user the procal is good enough.

If you wanna shell out a little extra $$ I would say Superchips. I have been running mine for a while and never have had any issues. Just my .02
