What did you find wrong with the oil temps? Extremely high? i also have the Toque pro app and one of the pids puts oil temps just cruising were 280+ very quickly. Guess the GM pid reads incorrectly , reading way high and you have to use the generic pid. The generic pid to me correlates to what I feel oil temp should be(10f-20f over coolant temp). But it does look like the active cooling system is used in two ways. One to warm the oil up to aprox 226f-236f. The other aspect to cool off the oil temps above 236f which this truck will do even unloaded.. Its really neat to watch when you are monitoring both pids together. Think this is why many have stated some bigger temp swings, especially once the oil temp reaches just over 200f and the truck is trying to increase the oil temp.. I've seen coolant temps as high as 226f when the truck is trying to increase the oil temps and coolant temps as low as 185f when its trying to bring down the oil temps down from 250f-266f. Interesting technology, different operation from what were accustomed to and would love to talk to a GM engineer about it.
My 2020 rides just like that paved roads. I can get the rear to step out on just regular roads. Hell it will do it on a Interstate. I haven't taken it down the washboard dirt road yet. Already know the outcome.
Something about the transmission going into neutral if the range sensor has an error
This is on the 8speed.
Was reading over the GM OEM repair information(I don't work for GM). This particular code repair tree has what I call poor diagnostics. You don't check wiring at all. Basically if the code sets and there is no other codes. Replace the Exhaust Particulate Matter Sensor. Hopefully GM will get to the bottom of it.
Kevin Anyway your employer does anything for GM? There is a supplier discount. You could also have a friend or family that works for GM/vendor. They can share the discount. I just bought a 20 crew cab 3.0 over the weekend. On a msrp of $51835 Supplier discount was $2932.

Just bought a RST 3.0 Duramax over the weekend. FYI Supplier discount made for just over $2900 savings off MSRP. This dealer had five RST Crew and one Sierra SLE Crew all lightly optioned trucks alone.
