Default Transmission troubles..
Got truck tuned.. Cruising or flooring it, it won't down shift sometimes.. It stays in 3rd, then maybe it will down shift.. Pulled codes p0700, p0712, p0807, and p0833.. Not sure if transmission is going out or it's an electrical issue.. Anyone with same issues?? Hoping it's just a relay or something small

Did it do that before the tune?

If not, then get the tuner to fix it.
If so, then it might be a Mech problem?

It started doing it about 2 weeks ago.. It felt as if it was under load.. When he was tuning it, he said it was in third gear

You see if he can put the stock transmission tune back in?
