Trans Snafu and ???

Last time (the only time, actually) I had this happen to me it was the shifter cable... it broke somewhere inside the sheath. Move the shifter, check the linkage at the tranny and see if it's actually moving when you move the shifter.

The time it happened to me was in the 1st round of a $10,000 race. Right after I did the burnout, I shifted it back from 3rd to 1st, the cable broke and slammed the tranny into park. That sucked. :-(
