Should I need to worry?

Hi folks. My first post so getting close....Ho Ho Ho ! My question is two fold. I just purchased a 2012 825i with 130 hours on it and looks like new. Very excited as we have 4 other Deere products with no issues. My wife and I drove almost 2 hours to pick it up and after paying went to put it on the trailer we rented and it seemed slow to get into gear and rather hard to shift. The parking lot was ice covered so perhaps I didn't feel the back wheels spinning. Got it moving after applying a lot more gas and took it over to the trailer. I took a bit of a run at it and got it up but not centred so it felt like it popped out of gear and went back or did I put it in neutral in my haste. Don't know but when it was in 4x4 the front wheels wouldn't kick in. The mechanic came out and looked under it and the drive shaft was turning but not the wheels kicking in. Needless to say I never got to take it home. They are working on it. So my questions are:
1. Do I need to worry as I found other similar issues with shifting etc. and had to do with the clutch?
2. And this one is easy. I have already bought a Superwinch for it and wondered if there were any after market in/out switches that would fit in the dash cut outs.
Long winded so I apologize. To all my new friends in here have a great Holiday and a safe and Happy New Year. Jack:)

Update: Hello again. No, I don't need to worry after all. The mechanic called and seems the issue is no power to the solenoid to the front end so very happy. Won't have it till after Christmas but worth the wait. Still looking for the dash switch however. Thanks Jack
