I just purchased a 2004 Mustang
GT convert about 80k miles on it, manual transmission.
I have noticed when I shift from first to second gear, I hear a bit of a "thunking" noise. I don't notice this when going from neutral to first or to second, third, fourth or fifth. It is not very loud but it's there. I did not notice it at all when test driving it, so I may just be paranoid.
I haven't driven a standard in a long time, and I have never driven a standard transmission Ford nor a car with any power in general, so I am not entirely sure what is normal and what is me just driving poorly.
After searching and Googling, some say this is normal, some say it could be the U-joints, motor mounts etc. Any opinions?
