Question:
Can I install the mainshaft myself, or should I hire a professional?
Answer: While some experienced automotive enthusiasts may attempt to install the mainshaft themselves, it is generally recommended to hire a professional mechanic. The installation may require specialized tools and expertise to ensure proper alignment and function. Improper installation can lead to further mechanical issues and safety concerns.

Question:
What should I do if the 5th gear is still slipping after mainshaft replacement?
Answer: If you continue to experience slipping in 5th gear after replacing the mainshaft, it’s crucial to have the entire transmission system evaluated.
