Best Answer

When shifting a manual (or standard) transmission on a vehicle, if you hear excessive knocking noises immediately after shifting, you are probably:

1) Shifting into the next highest gear too soon, or
2) Shifting into the wrong gear - for example, going from 2nd to 4th gear, or
3) Not running the engine fast enough after shifting to the next highest gear, or
4) Your engine is out of tune if you know you're doing steps 1,2 and 3 correctly
