Hey guys, I was wondering if anyone else is experiencing this or is it just me. I have an 03 corolla sportivo and just recently I notice that the car struggles abit in reverse. It would rev really loud and only reverses a little bit. I just changed my clutch recently, under 1000km. Could it be my gearbox? I've also notice recently that when I start my car there would be vibration like sound coming from the rear boot. Could this be related? Any help would be appreciated. Thanks guys!
