pulse generator is bad
In a manual transmission vehicle, gear shifts work by using a gear stick to change the position of gears inside the transmission. When the driver moves the gear stick, it engages different gears to control the speed and power of the vehicle. This allows the driver to shift between different gears to match the engine's speed with the desired driving conditions.
Could be the gears slipping. Might need new gearbox.
6 e-gear shifts
It runs to the modulator valve from the intake manifold. Its what makes an automatic trany shift thru the gears. Low vacum = quick shifts and High vacum = long between shifts.
gears are slipping or not enuff fluid in transmission
syncro??
Replace the chain and both the cam and crankshaft gears.
2006 ion shifts hard
More than likely, bad motor mounts
Derailleur gears work by using a mechanism to move the chain from one sprocket to another on a bicycle. When the rider shifts gears, the derailleur moves the chain sideways, allowing it to engage with a different sprocket, which changes the gear ratio and makes pedaling easier or harder.
To shift gears on a bicycle, you use the gear shifters located on the handlebars. Pushing the shifter in one direction makes it harder to pedal (shifts to a higher gear), while pushing it in the other direction makes it easier to pedal (shifts to a lower gear).
A car will sound very rough and jerky when it shifts between gears. It may stall and almost seem to sputter. This is a dangerous situation as it can completely cut out suddenly.
