Transmission Shifts Hard

Transmission Shifts Hard

Diagnostic Aids

Hard shifting can be diagnosed easily. You should perform a static and dynamic shift test also. Many simple factors could occur such as, excessive clutch pedal free travel, insufficient fluid, excessive fluid, or the wrong transmission lubricant. A misaligned transmission can also cause hard shifting, as well as a worn or defective clutch, binding of the shift control. Many internal components can also play a factor in hard shifting such as, the front bearing retainer loose or cracked, the synchronizer worn, damaged, or improperly assembled. Failure to fully depress the clutch pedal while shifting causes hard shifting.
