more than likely your shifting arm is either bent..or broken..the only way to find this out..is to remove the side cover and inspect it...if i remember right..it's on the right side..so you will need to remove the right side cover in order to see how bad it is..if it's bent or broken..you will need to remove the clutch pack in order to get to it..i'm not for sure on this part..it has been sooooo long sinse i worked on a trx 70.
