Locking Style Trans. Dipstick - GM TH350 Long

The Locking Style Trans. Dipstick - GM TH350 Long by MOROSO is a precision transmission fluid measurement tool engineered for hot rodders, street racers, and professional mechanics who demand reliability during high-performance driving. This locking dipstick eliminates the frustration of traditional sliding dipsticks that can slip out of the transmission tube during aggressive acceleration or rough road conditions, ensuring accurate fluid level readings every time you check your TH350 transmission. Built for enthusiasts who understand that consistent transmission fluid levels directly impact shift quality, heat dissipation, and long-term durability.

Constructed from solid steel tubing with a durable black powder coat finish, this dipstick features a secure locking mechanism that clamps firmly to the transmission dipstick tube, preventing accidental withdrawal during vehicle operation. The OEM length design (24.9 inches overall) maintains factory fitment while the locking collar design provides a positive grip that won't vibrate loose on rough surfaces or at highway speeds. The solid tube construction resists bending and flexing, delivering consistent, repeatable readings that rival factory equipment—critical for tuners monitoring fluid temperature and viscosity changes during dyno sessions or extended track use.

This locking dipstick is purpose-built for TH350 transmission applications in classic muscle cars, street rods, and modern restomod builds where OEM reliability meets custom performance demands. Installation requires no modifications to the transmission case—simply remove the factory dipstick and swap in the MOROSO unit, then hand-tighten the locking collar until snug. Professional rebuilders and DIY enthusiasts alike specify this design for shops where transmission servicing is routine and accuracy cannot be compromised by equipment failure or operator error.
