A band in a transmission is glazed. What must you do to correct this condition?

• A. Replace the band
• B. Sand the outside of the direct drum
• C. Replace the servo with one that uses a larger diameter apply piston
• D. Both A and B

Answer: (D)

When a band in a transmission is glazed, it means that the surface of the band has become smooth and shiny, often resulting from excessive heat or wear. This condition can lead to poor engagement and slippage, which hinders the transmission's performance. Correcting glazing typically requires actions that will restore the band’s ability to grip effectively. Replacing the band ensures that any damage or wear is eliminated entirely, restoring optimal functionality. In cases where minor glazing occurs, sanding the outside of the direct drum can help roughen the surface, allowing the band to engage properly again. This two-fold approach—replacing a severely damaged or worn band while also preparing the friction surfaces—can help ensure that the transmission performs as intended. Therefore, addressing both the replacement of the band and sanding the drum can effectively remediate the issues caused by glazing, leading to improved engagement and overall performance in the automatic transmission.
