Smartcar 2012 not shifting into reverse or 1st gear

Hello, I am new to the forum but I was looking to get some ideas on what might be happening with my 2012 smart for two passion. I bought it second hand and have had it for about a year. It has 68,000 miles on it and has been quite a pain with repairs recently. I had to replace the control module at the dealer recently and not long after that my check engine light came on when I started the car up. When I start my car up in the morning and try to put it in reverse, it feels like the gear is slipping and it won’t go into reverse. When I try to put it in drive the same gear slipping happens. The only way I can get it moving is to switch to the manual mode and use my paddle shifters. Once I have done that the car dives fine for a while but the problem is reoccurring. I have taken it to The dealer and they couldn’t figure out the problem. I was wondering if it sounds like the clutch is bad or if others have experience this problem? Any advice would be appreciated.
