Just brought a gen 4 si and the auto trans is slow + clunky to change gears, and gets worse as it warms up. There is what looks to be a exhaust light on all the time and a check engine light that only comes on when warm (related or no?). Also the screen with the temp and fuel gauge is very dim (I am thinking a backlight? If so is it replaceable or do I have to put a whole new screen in?) Thanks.
