Compatibility and Assembly Notes
During transmission overhauls when gear replacements are performed, checking the tooth surfaces of cooperating gear groups and clutches together directly extends service life. Replacing worn or damaged side elements ensures the newly installed gear maintains load distribution and prevents potential premature wear in the powertrain.
