Started downshifting to stop a 4 way and my super comp is now locked up in 1-2 gear. It just locked the back tires up. I've drove it in 3rd gear home now and I'm a little stumped. I wonder if the transbrake sol. maybe has something stuck in it or maybe the planetary is broke. Anyone had this happen to them? It does do nice 50 mph rolling burnouts though! Thanks.
