i left a light two days ago, took off in 1st normally and stepped into it, threw second and then third as soon as i took my foot off the clutch in third i heard a pop and the the clutch didnt grab in third anymore not to mention that i cant even get to the far left to go into 1st or second, i had to drive home in 4th, 5th and reverse , they all still work normally. i heard no grinding prior to this incident nor did i have any tranny problems, all tranny fluid has been replaced with amsoil at 10k intervals, i checked the shift linkage for any issues and everything looked fine. so im stumped, any help in determining this problem is appreciated.

P.S. im tearign out the tranny tomorrow morning with a couple local orgers, just wanted a few pointers on where to look specifically for issues.
