GM TH350 Trans Dipstick 34in Chrome

The GM TH350 Trans Dipstick 34in Chrome by Specialty Products Company is a precision transmission fluid level gauge engineered for vehicles equipped with the TH350 automatic transmission. This 34-inch dipstick delivers accurate fluid monitoring, a critical maintenance function for transmission longevity and performance across marine and automotive applications. The solid steel tube construction with chrome finish resists corrosion and provides long-term durability in salt-air and moisture-heavy environments where transmission fluid accuracy becomes essential.

The 34-inch length accommodates vehicles with extended engine bays or non-standard dipstick tube positioning, ensuring the gauge reaches the transmission pan without kinking or binding. Chrome plating protects against rust and oxidation, maintaining readability of graduated markings under repeated use and exposure to seawater mist or freshwater spray. The solid-tube design eliminates the flex and wear common in hollow-shaft alternatives, preserving accurate fluid-level readings across thousands of fluid checks. Transmission fluid temperature and level directly impact shift quality, clutch wear, and heat dissipation—making an accurate dipstick a foundational maintenance tool.

This dipstick serves boaters, marine mechanics, and automotive enthusiasts who rely on the TH350 in inboard engines, recreational vehicles, or classic restorations. Weekend fishermen running center consoles or express cruisers with TH350-equipped powerplants depend on this gauge to catch fluid condition problems before they escalate into transmission failure. Serious offshore operations and commercial marine applications benefit from the durability and corrosion resistance needed in full-salt-water duty. Part number 7402 is a direct-fit replacement for worn or damaged OEM dipsticks.
