Buick LaCrosse transmission issue, unable to engage reverse on Buick LaCrosse

Some Buick LaCrosse owners report experiencing difficulties with engaging reverse, which may stem from several underlying issues. Commonly, owners have noted delayed or rough shifting, characterized by hesitation during initial acceleration or jerky transitions between gears, often attributed to software glitches or mechanical problems within the transmission. Additionally, low levels of transmission fluid or leaks are frequently reported, typically caused by faulty seals in the transmission or driveshaft that lead to fluid loss. It is recommended that owners facing these issues have their transmission system inspected by a qualified mechanic for proper diagnosis and resolution.
