feeling down right now. Was doing some inside jumping in our supply shop and things were going fine. Last jump was only a few feet and after it landed no more go, lol. Runs fine, spur gear is good and spinning, but it appears whatever is going on inside the trans box is not good. it just free spins in forward and reverse. Is this an easy fix? what kind of money does this trans require usually to repair? I was really looking forward to running it at the track this saturday when it finally gets warm here.
