well that's what i'm trying to figure out , did the traction control keep the tires from spinning ? i mean i didn't even hear a chirp or felt an almost immediate pull forward like there was when my TC wasn't working. the rpm's went way up, then they came down like it shifted gears , then i went forward faster. to this point i've never noticed any kind of slipping , but as i said i've owned manuals almost my entire life and never had TC so i can't say for sure what happened. in the few months i've owned the car , i've never thought it's slipped. i've always thought the engine moved to much on hard acceleration , that's why i turned the mounts to see if it would help.
