This U151 valve body fits Aisin U151E/U151F/U250E 5-speed automatics in Toyota Camry Highlander RAV4 and Lexus ES RX. The valve body is the hydraulic control core with spool valves and passages. Common failure is main pressure regulator bore wear causing pressure loss leading to 1-2 shift shocks and TCC issues (P0741). This 6-bore main pressure regulator repair kit fixes worn bores directly at lower cost than full valve body replacement.
