okay so today i was driving.....and a red came up...so i slowed down..then it turned green...i hit the gas going around like 20mph...and the rev just reved up as if it was in neutral.....i looked to see if i was in N but it wasnt i was in fact in d5...this has happened a couple of times already....what should i do?

another Q...is this normal?

i happens usually when im going like 25mph.....i flooor the car......and the car downshifts to 1st...and hits the rev limiter like crazy.....and then i let go of the pedal so it will shift to 2nd... inever noticed this about my car when i first got it....?
