PLEASE HELP - My automatic transmission truck wont go into gear

Have a Freightliner Smart Shift and it started doing the same thing. Ended up being the clutch was shot. $4500 to replace it.

 

I have some what of the same problem my Alternator was giving off high voltage put in a new one now my truck wont go into gear there trying to figure out why now there saying that theres no power to the transmission computer

 

I have a freightliner cascadia 2013 my first truck

 

what ever it is that's going on with it I hope it's under warranty

 

I hear you all the way worse decisions I ever made

 

every time the trucks in the shop it's for something that not covered under warranty isn't that something

 

My 2007 freightliner is currently putting out high voltage and won’t go into gear. I’m setting at an old closed down gas station in carrizozo New Mexico trying to get a tow to a shop. Did you get the issue resolved and if so what was the fix?
