I had the same thing on my '00 SVT, 2-3 shift at Higher RPM'S (over 3k), bad 3rd gear, 3 & 4th gear synchro's. I would bring it back if you have any sort of 30 day 1,000mi type warranty.. Thank GOD I did.. it was 13.2 hours of labor plus parts(although Terry says it should take about 11 hours, but he knows what the hell he's doing

)
