95 Firebird formula. Lt1 with 4l60e. Cold air intake, and complete msd ignition with multi spark box so nothing crazy. Was cruising about 60 and lost all gears so I pull over on a side road and Shut the car off, tried starting it again it would just crank.kinda had a off sound to it . Got it towed home and when I finally got around to messing with it I noticed when I turn it over just the converter and flex plate spin. Not the motor. The motor still turns fine by hand. Any ideas? I had a friend tell me that I most likely blew the tc. Any suggestions help. Most likely gonna end up dropping the subframe tonight or tomorrow.
