Flexible Trans Dipstick GM TH400 B/H Mount

The Flexible Trans Dipstick GM TH400 B/H Mount from Racing Power Co-Packaged is engineered for builders and mechanics working with Turbo 400 automatic transmissions who need reliable fluid level monitoring in modified engine bays. When you're running a tight underhood layout—whether in a street rod, custom hot rod, or high-performance swap—routing the dipstick around headers, intake manifolds, and auxiliary components becomes critical. This flexible dipstick solves that problem by allowing you to bend and position the tube to fit your specific plumbing without compromising accuracy or durability.

The design features a flexible tube construction that accommodates tight bends and non-standard routing while maintaining structural integrity and accurate ATF level readings. The B/H mount designation indicates compatibility with both B and H series bellhousing patterns on TH400 installations, making this dipstick universally applicable across most GM platform swaps. Racing Power Co-Packaged manufactures this component to OEM tolerances, ensuring the graduated markings remain legible and repeatable across temperature and mileage cycles. The flexible element is heat-resistant and designed to withstand the thermal environment of modern engine bays without warping or becoming brittle over time.

This dipstick is ideal for hot rodders, drag racers, and engine swap enthusiasts who cannot use factory rigid dipsticks due to headers, turbo manifolds, or custom intake setups. Installation is straightforward—simply mount the dipstick tube to the transmission pan and route the flexible section to clear your engine's accessories. The compact 23.55-inch length and 1.5-inch width make routing flexible enough for even the tightest engine compartments. Whether you're verifying fluid level before a weekend cruise or monitoring ATF condition during break-in, this Racing Power Co-Packaged dipstick delivers the reliability and flexibility that serious builders demand.
