ATC35L/ATC45L Main shaft common issues
While specific information about the ATC35L/ATC45L main shaft's outer splines might be limited (due to the absence of official detailed technical documentation), issues with outer splines on transmission components are not uncommon in general. Here are some potential problems that could occur with the outer splines:
Wear and Stripping: The outer splines can wear down over time due to friction and stress from engagement with other components, such as the rear flange (27107593440 is the most susceptible) or clutch (friction plates). This wear can eventually lead to the splines becoming stripped or rounded, resulting in loss of engagement and transmission malfunction.
Corrosion and Rust: Exposure to moisture or contaminants can cause corrosion and rust on the outer splines. Corrosion weakens the metal, leading to premature wear and potential failure of the splines.
Improper Engagement: If the outer splines are damaged or worn, they may not properly engage with mating components, leading to excessive play or slipping.
