Locking Transmission Dipstick Suit GM TH400, Gold Iridited, Tight Fit Applications

Why install a locking dipstick?

Many transmissions build up pressure. This pressure can blow out the dipstick, allowing trans fluid to spew everywhere. With Hughes' locking tubes, you keep the fluid in the trans, which means greater reliability and a sanitary engine compartment.

All of Hughes' filler tubes are gold irridited. And all assemblies are manufactured to exacting tolerances with tab mounts.
