High oil temp and pressure sluggish moyor

[Crosscarriers]

Ok so with it being covered under warranty still im going to take it back but i would appreciate any advice on what i need to make sure they check so they dont weasel their way out of anything. Or better yet is there anyone or who you guys would recommend to have look at it and diagnose it before i take it back to the dealer or is there anyone on here that would do it? Of course i would pay them for their time! Id just like to make sure the dealer actually fixes whats wrong instead of some bullshit!!! Please let me know! Thanks Guys!!
