Need help with this (First time owner of a Volvo)

[S70GUY]

First of all, It's nice to be able to find a place full of people who also like the Volvo brand, I come here for help My problem is that I have zero knowledge of automotive mechanics, and a few weeks ago I got an S70 GLT for $450 The car already starts and all that, but I have a problem with the so-called Limp Mode I want to know how you guys have fixed it, since I can't find much to do, And I would also like to be able to learn more about this.

First...you need to get the codes read for abs,auto transmission(orange arrow),engine and to top up coolant or replace coolant sensor if coolant is at proper level.

Car in in limp mode because of transmission codes stored and starts in 3rd gear.

Vida or dealership for codes readout.
