What makes a 1992 Honda accord not shift to overdrive?

A 1992 Honda Accord may not shift to overdrive due to several potential issues, including low Transmission Fluid levels, a faulty overdrive switch, or a malfunctioning transmission control module. Additionally, problems with the throttle position sensor or issues within the transmission itself, such as worn clutches or bands, can prevent the vehicle from engaging overdrive. Regular maintenance and diagnostic checks can help identify and resolve these issues.
