Its been a few months since i got my clutch installed. Today while i was driving my transmission started to act up. Like I was at a light and started to go and it felt like my car was in 5th gear (it was really in first). I take it out of gear and put it back in and its normal. And when i am going all the other gears are just as strong as they were before. What do you guys think clutch or tranny?

I also replaced my master cylinder when I did the clutch cause it was leaking.

It does it now about 1-3 times a day...
