My 98 GS has 180k on it now, over the winter i got a pcm and rebuilt my whole front suspension. Last year before i replaced my long block from a blown int gasket at the track, i had run a best of 14.2 at 99.5 mph. I could run these times easy. Well after the motor replacement, tune, and suspension my best times have been 14.3 at 99.0 on a cool night, but i have noticed that when i am launching and get going i hear a odd noise from the front of the car. Like something slipping. After the suspension it gets great traction but tonight at the track my best time was a 14.3 at 97.0 and seems like i kept hearing that noise more than before. Are my first gear clutches worn out or is something else here the problem? I never had this noise until the pcm install and suspension rebuild. Shifts fine on the street and no noises, just under wot runs.
