1. Difficulty shifting into first gear and reverse: This issue is often caused by wear or looseness in the shift mechanism or related components, such as the shift linkage, bearings, or cables. Replacing this shift lever kit will realign the shifting mechanism, making it smoother and easier to engage first gear and reverse, reducing shifting difficulties.
2. Shifter rotation issues: If the shift lever exhibits abnormal rotation (such as wobbling or difficulty turning), this is usually caused by loose or damaged parts in the shifter assembly. Replacing the kit will restore the correct fixing of the shift lever, eliminating unnecessary rotation or looseness.

If you're replacing the part yourself and encounter difficulties, it's recommended to have a professional mechanic handle the installation to ensure the new shift lever kit is correctly fitted, solving these problems and restoring a smooth, reliable shifting experience.
