"Did the engine rpm go way up or did the car just kinda lug & gradually accelerate?"
Im having this problem right now, rpms increase to 4k sometimes when im trying to move from a stand still, its a ATX but it feels like im holding the clutch in and slipping it out at 4k. Im going to try that "1-2 bang" shift fix to see if thats the problem but i dont think its the same symptoms
