Wondering if anyone has any idea of what this can be? My transmission doesn't make any grind noises and the clutch engages fine (although a little high it seems) with no slippage. Whenever I accelerate from a stop from first to second gear I get one single click while the gear engages. The sound seems to disappear from third gear and higher. This sound is not related to turning such as certain posts I found during a search; this happens on straights and just in general. Any ideas guys?
