Hello all,I have a 04 A6 4.2l quattro with a 5hp24a trans.My problem it started going like into neutral when stopped with the car in drive.If you reved it up it would lunge forward but make a noise like a old granny box 4wd pickup in four wheel drive low.I changed fluid and filter,no better,I checked the tcm,no water or smell,I checked all trans wiring seems fine.When testing actuator components I get codes 0752,0757,0762,1762,1815,1820,1825,1829,1834,1745. What would make all those codes.I took off the pan and looked at all solenoids tested them they all work. HELP.
