So, i have had the wrx for like 5 days now (at about 240 miles) and I have been sticking to the break in period rules pretty well. However today as I was driving i let it rev up to 4 and when i shifted gears the rpms jumped to 5,000 before going to the next gear. It happened twice. i think my foot was still a little on the gas as i was shifting (still somewhat new to stick) .Think any this did any harm?
thanks guys, im a noob i know
