Drive Belt (High-Performance OEM)
The drive belt can develop flat spots or glazing from heat-induced slippage. These irregularities increase the friction between the belt and the primary clutch sheaves at idle, preventing the belt from sitting neutrally and causing it to 'grab' the transmission, leading to hard shifts and clunking upon engagement.

Primary Clutch One-Way Bearing Kit
This bearing allows the drive belt to remain stationary while the engine idles and the primary clutch spins. If the bearing becomes contaminated or seized, it creates parasitic drag on the belt, which keeps the transmission gears under tension, making it physically difficult to move the shifter between ranges.

Primary Clutch Rebuild Kit (Rollers and Buttons)
Internal wear on the spider buttons and rollers within the primary clutch causes the moving sheaves to bind or move non-linearly. This mechanical binding prevents the clutch from fully retracting at low RPMs, maintaining unwanted belt tension that results in the reported shifting difficulty and clunking noise.
