ur clutch is slipping, replace ASAP b4 it goes all the way. and launching all the time is a good way to ruin ur clutch faster h:

and it may seem like ur gears are completely gone but they rnt. when my throwout bearing was seazing my gears would grind like crazy. got a new clutch, new bearing and tranny is perfectly fine. (has 208,xxx miles on it). so just get a new clutch kit and ul b good to go. once u get the new clutch, then gauge the condition of ur tranny.
