The primary design function of the OE end plug in listed Toyota/Lexus transmissions is to prevent critical pressure loss by capping the bore. OE end plugs rely entirely on small clearances between the end plug and bore to confine hydraulic fluid under fluctuating pressure. End plugs are often tasked with a secondary role functioning as a spring stop or valve stop. The repetitious and varying actions of fluid pressure, spring motion and valve impact cause wear at the end plug and bore mating surface and can distort the shape of the end plug. High-pressure fluid leaking through the clearance gap can, with time, erode the surface material of both end plug and bore. Eventually the cumulative loss of hydraulic integrity leads to low pressure in critical circuits. Complaints vary depending on the location of the worn end plug but are always related to pressure losses. O-ringed end plug kit 168740-10K replaces worn, distorted or eroded end plugs in Toyota/Lexus UA80E/F and UB80E/F series transmissions. end plugs have an O-ring seal that reduces leakage further by blocking off worn areas of the bore which the new end plug alone could not seal. * Minimal end plug-to-bore clearance with added O-ring for positive seal* Drop-in Zip Valve parts install quickly and easily [Learn More About Zip Valve Drop-In Repairs]/zip_valve

Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
