Locking Trans Dipstick TSI / Reid PG Car

The Locking Trans Dipstick TSI / Reid PG Car from Allstar Performance is a purpose-built transmission fluid measurement tool designed for hot rodders, drag racers, and serious engine builders who demand precision and reliability under demanding conditions. This locking dipstick eliminates the guesswork during high-rpm runs and track sessions, where vibration and aggressive acceleration can dislodge a standard dipstick from its tube. Whether you're tuning a vintage Powerglide or running Reid transmissions in a competition vehicle, this solid tube design keeps your fluid level reading accurate and your dipstick securely in place.

Manufactured from steel and finished with cadmium plating for corrosion resistance, the Locking Trans Dipstick features a solid tube construction that resists bending and warping under sustained heat and vibration. The locking mechanism secures the dipstick firmly within the transmission tube, preventing accidental ejection or misalignment that can occur during aggressive cornering or acceleration. Its 27.7-inch length provides full-depth access to transmission pans and deep sumps common in high-performance applications, while the 6.25 x 2.95-inch envelope ensures compatibility with tight engine bay layouts. The cadmium finish provides long-term protection against corrosion, essential for vehicles stored or driven in varying climates.

This dipstick is engineered specifically for Reid and TSI Powerglide transmission applications, making it an essential upgrade for anyone rebuilding or modifying a classic hot rod, street machine, or dedicated track car. Mechanics and fabricators choose locking dipsticks to eliminate mid-run fluid level uncertainty and potential transmission damage from running low during competition events. Installation is straightforward—simply swap your existing dipstick for this locking version, ensuring you have consistent, reliable fluid level readings every time you hit the track or take your vehicle out for a high-performance drive. The solid steel construction and proven cadmium finish mean this dipstick will outlast multiple transmission overhauls.
