Need a new gearbox. You get a grinding noise only in first gear when you accelerate fast . second gear and the rest should be fine.
broken stsarter or ring gear.
The grinding noise can be an indication of a bad gear in the transmission. The grinding noise can also indicate a problem with the clutch.
The noise is the teeth on the flywheel grinding on the teeth of the starter. Check to see if the starter is loose, this is the most common cause of that noise.
Smoother transitions between gear ratios. Less 'grinding' noise A more pleasant driving experience Less wear on the gear box
sounds like a wheel bearing.
You probably have a "throwout bearing" going bad.
countershaft bearing could be problem
slipping clutch? get a new one
hmmmm. sounds like u need to have the clutch looked at.
To stop a standard transmission from grinding into third gear, check the level of the transmission fluid. If the noise continues, consult a mechanic.
Throw out bearing is bad.
I assume you are referring to a manual transmission. Grinding while changing gears is an indication of a synchronizer going bad. Until you get it fixed, try double clutching when shifting.
