    i work at a tranny shop and fixed this problem a few times. the overdrive drum has a short shaft at the end of it with very fine splines. after a while the splines wear out and strip, causing the drum not to spin. the tranny wont blow up, but i recomend getting it fixed asap because of the fine metal shavings in the tranny.
