Have motor and trans in a sandrail. When in nutruel, car will roll but engine still turns.When put into any gear 1st thu reverse, car will not move.When letting out clutch car acts like e-brake is on and will not budge. If you let clutch out all the way it dies. What do you think is wrong. Could it be in my trans or in my shifter?.Where do I start? Any ideas. Thank you
