I bought a 1995 Hyundai HGG1 (I believe can’t find any numbers) engine runs great, 8.5 Suzuki, but will not go forward or reverse. No warnings I pulled it out of the garage and when I went to put it back it wouldn’t go forward or reverse? Any help? The clutch is engaging and shaft is turning going into to transmission. Considering all options - to include selling as is. Thanks for any help.
