DS90X broken trans case and gear skipping

So my boy’s quad cracked the trans case where the output shaft that drives the primary gear on the chain looks to have separated. It allows the gears to jump over each other in the case as it opens up. It sounded like the chain was skipping gears.
I am wondering if anyone on here has pulled the engine to make a repair like this and if it is cost effective to spend the money to buy the casing and maybe some gears inside. I am guessing the bearing failed in the end of the casing or a metal part failed in the trans allowing it pass between the gears cracking the case.
I purchased a DVD service manual to get started but thought I would ask for some help first. If you have some insight on the cost of this repair before I take I would appreciate it. I found a new 2015 for 3K and wondered if I would just be better off going that route.

Thanks, Wally
