transfercase Transfer case/4x4/clutches 2017 silverado

[ABT15-1500]

Whats up guys, hope all you GM people are doing great. Ive got a 2017 silverado 5.3

Broke my transfer case gears around a month ago and tc actuator, replaces the gears with nitro gears and axles 4.11 and a new actuator. My truck is modified so i dont have warranty, costed me a lot to get the truck fixed from the middle east and parts+labor is much more than what you guys pay in the states. Anyway everything was fine switched the  knob to 2-auto-4hi all was good on the road, i just kept the thing on 2wheel drive all the time. I drive usually in the desert/dunes and decided not to use 4 wheel drive at all unless im stuck. didn't get stuck for a good while till this weekend, got stuck switched to 4hi light changded felt the car turning to 4wheel and my friend gave me a tow and as soon as the car got out the sand got the service 4 wheel drive message. turned it to 2 wheel drive and light was stuck on 4hi however the car was not on 4 wheel drive ( did some doughnuts to confirm if the car is on 4 or 2 drive. Anyway now the car is back at the dealership and they want to charge me 2500 usd dollars just to pull down the transfer case and diagnose the issue. The mechanic said he assumes its the transfer case clutch.. Wanted to know your thoughts on this ? plus Isnt their an upgraded transfer case and clutch ? or a rebuild kit ?  What are my options if i want to upgrade the transfer case if i have any ? tried google and didn't find much. HELP!!!!!!!!

What are the transfer case's trouble codes?  Magna Power transfer case?  MP3023?

Not really sure will double check with the dealership, checking out magna power right now and it looks pretty cool. I just decided to take the truck to the shop that built my long travel kit and will let them open up the whole transfer case and fully rebuild. thanks for the reply man really appreciate it
