I bought the car a few weeks ago and drove it home without a problem. But then something weird happened...The first gear works flawlessly, but when it goes into second, I get nothing! It just revs up like its in neutral. After a few seconds, it kicks into limp mode. I know limp mode usually selects 3rd gear to operate in, but it does the same thing as 2nd gear. It just revs up. I've done some research and cant seem to find any help. I took it to my mechanic and he put it on the lift to see underneath. He told me that the oil pan was clean and that it looked like someone had already been into the transmission. He said that I probably need a new one... I dont want to take his word for it since he only looked at the outside. Any help would be great!
