Locking Trans. Dipstick & Tube - TH400 B.O.P.

The Locking Trans. Dipstick & Tube - TH400 B.O.P. is a critical upgrade for high-performance builds utilizing the Buick, Oldsmobile, and Pontiac pattern Turbo-Hydramatic 400 transmission. In racing and high-torque applications, internal transmission case pressure can force a standard dipstick out of the tube, leading to hazardous fluid leaks and potential fire risks. This ATI Performance "Trick Stick" addresses this vulnerability with a positive locking mechanism that ensures the dipstick remains seated even under extreme operating conditions.

Constructed from high-grade steel with a durable cadmium finish, this solid tube assembly is designed for longevity and resistance to the harsh thermal environment of the engine bay. The 23-inch length provides an accessible point for fluid level monitoring, while the transmission-mount design offers a rigid installation that eliminates the vibration and movement common with flexible alternatives. For builders seeking technical specifications that prioritize safety and reliability, this unit is a necessary upgrade over stock components.

Installation of this ATI406491 model is straightforward for mechanics familiar with the TH400 platform. The solid tube design ensures an accurate fluid level reading every time, which is vital for maintaining the hydraulic integrity of a performance transmission. By choosing a locking configuration, users comply with many sanctioning body safety requirements regarding fluid containment, making it a standard choice for competitive drag racing and heavy-duty street use.

When looking to buy a reliable fluid management solution, the solid construction and cadmium plating of this dipstick and tube assembly offer superior protection against corrosion and mechanical failure. This product is sold as a complete unit, providing everything needed to secure the transmission fluid system. Reviewing the build requirements for any B.O.P. TH400 setup reveals that a locking dipstick is not just an aesthetic choice, but a functional necessity for high-output vehicles.
