I do not track race or street race. However I like to get on my LS3 every once in a while.

I have 2600 miles on the car now (I have changed the oil 2 times already w/Mobil 1 full synthetic) and I do not abuse it. However, whenever I shift from 1st to 2nd gear at higher rpm's, it grinds. But if I keep the clutch in long enough it will go into second with lots of effort and by that time the nose has dropped and the rpm's have dropped so much that it's not a smooth transition. I'm not sure if it's the tranny, synchros, clutch, pressure plate, flywheel, slave cylinder, throw out lever or throw out bearing. (doubt it's the bearing) Am I not shifting properly? Should I powershift or speedshift? Probably not any better for the tranny or clutch assembly, right? I hope it's not the tranny. Could it be the clutch is smoked/glazed so it won't disengage or are my synchros gone?

I want to take it to the dealer, but I'm a little worried that they will give me a hard time or deny my warranty due to my mods. I have not touched anything from the throttle body to the cats though.

Mods:

Solo Peformance straight pipe catback system
Airaid CAI
Hurst short shifter (installed at Hurst facility in Chatsworth CA by Kenj, who is the engineer that designed the shifter)
