Why Aren T My Gears Shifting. After putting a few miles on your bike the cables will stretch as they wear. If your gears arent synchronized properly it wont shift gears smoothly.
Do you pedal while shifting gears. Different number of gears on the shifter and the cogs like Chris wrote. One main reason why the automatic transmission in your car may not be shifting smoothly is the ECM is going bad.
It is on top of the transmission coming out at a 45 degree angle toward the driver side.
If you have a manual transmission it may be that the clutch or clutch mechanism is worn out and not letting the clutch disengage completely or something similar or very poor shifting and gear change technique. The gears that arent coupled to the input or output shaft may be held still or allowed to rotate freely. They differ from the trigger shifters in that they dont have a lever extending from the handlebar creating a bit of a cleaner look. You must be pedaling when you change gears.
