If i give my car full throttle it will only kickdown 1 gear, this cant be right as it feels awefully slow, i thought it was suppose to kickdown 2 gears? I had a mechanic adjust it to drop 2 gears which made the car feel quite strong but now the mechanic who rebuilt the transmission said the reason the car was thumping was because the car was bringing down 2 gears "they are not suppose to bring down 2 gears"....this dosnt sound right to me as the box was playing up before the other mechanic adjusted the kickdown. So, what i want to know is, is the transmission suppose to bring down ONE or TWO gears?
