I have a Hisun Sector E1 UTV. Worked pretty good for a while but then started to run into issue with gear grinding noise. Will not engage in forward or reverse. When put into forward or reverse and press pedal can hear a whiring noise as if something is supposed to be engaging but is not. Occasionally it will grab in jolt forward momentarily but then ceases. No error warnings or codes given. Due to money restrictions, I really need to fix this myself. Has anyone had this problem and what could it be that is needed. Any help is appreciated. Thank you!
