Allstar Performance ALL69113 Locking Trans. Dipstick TH-400 Buick Olds Pontiac

Dipsticks feature a positive lock to keep dipstick in place and seal tight to prevent fluid leaks while sealing out moisture and debris. Steel case fill tubes have a gold finish, include a welded-on mounting tab and are fitted with a rubber grommet type seal which reduces the risk of leaks common with traditional o-ring seals. Locking dipstick tubes are required on 10.99 and faster drag cars.
