Hard Shifting

A low lubricant level, loose or worn shift lever, or loose, damaged shift housing components are common causes of hard shifting. If hard shifting is also accompanied by gear clash, synchronizer clutch and stop rings, or mainshaft gear teeth may be worn or damaged.

Hard shifting may also be caused by a loose, or misaligned shift cover, or alignment dowels. Worn, or damaged shift cover components will also cause hard shifting. Any of the foregoing faults will cause component bind and high shift efforts.

Mis-assembled synchro components will also cause shift problems. Incorrectly installed synchro sleeves, struts, or springs will all cause shift problems.
