Function of shift detent ball
When shifting gears, a spring pushes the detent ball into the groove on the shift fork shaft. This assists in maintaining correct gear-shift positioning while preventing jumping out of gear, and leads to a feeling of restraint when shifting.
 
Function of lock ball assembly
Prevents the reverse idler gear from moving when the transmission is not shifted into reverse.
