Hi guys, it's been a while since I've posted cuz I've simply been out enjoyingm y ride. However, all of a sudden today my Chalz decided it would stop shifting gears while the car is running. Shut off everything moves around fine but in the rare instance that I get it shifting while it's running, it shifts "roughly" to say the least. i'm not getting any gear grinding sounds or anything like that but like I said.. it happened pretty much all of a sudden. If I have the car running and try to force the shift the gear will slightly catch and the car will barely coast (that's how I was able to slowly back out my parking area at work to come home.) Please let me know where to start!! Thanks in advance for the help.
