Does the TC have Limited slip or an Open differential? I thought it was open. I locked the e-brake and dumped first gear. About 15-20 seconds later, I hit second. The rpms drop but then began to rise once again. The car gets to about 5k rpms and I release the e-brake. The car slowly takes off leaving a HUGE cloud of white smoke and two REALLY long black marks. The pavement was eaten down about ¼ inch where the front tires sat. The question is why did both tires spin if I have an open diff?
