Hey guys, just wondering if anyone had this problem before or has any idea bout it. It started yestreday, when I was doing my daily drive to work, I made a stop at a red light then all of a sudden as I press on the gas, from 1st to 2nd gear it was fine, but from 2nd to 3rd i felt this jerk as if it went into a lower gear and went right back up. Strange, i have never had this problem beofre, usally the shift are very smooth and you don't even feel a thing. My car is '01 GS300 with about 10k on it. Thanks in adavance.

 

Have you checked the fluid level? If it looks good I would try resseting the ECU!
