Black Trans Dipstick GM TH350/400 Firewall Mt

The Black Transmission Dipstick for GM TH350/400 Firewall Mount is an essential fluid-level monitoring tool for any serious builder or shop technician working with Chevy's legendary automatic transmissions. Whether you're running a vintage muscle car, street rod, or modern restomod, accurate transmission fluid measurement is non-negotiable for engine longevity and shift quality. This firewall-mounted dipstick eliminates guesswork during initial setup, fluid top-offs, and routine maintenance—critical when fine-tuning transmission temperature and pressure for optimal performance.

Designed specifically for TH350 and TH400 transmissions with firewall-mounted configurations, this dipstick features a black finish that resists corrosion and blends seamlessly into engine bays. The firewall mounting location—rather than traditional pan-side mounting—is typical in tight engine compartments or when chassis geometry demands unconventional trans placement. The accurate graduated markings ensure precise fluid level reading at operating temperature, preventing overfill conditions that cause foaming and underfill scenarios that risk bearing starvation. At just 0.95 lbs and compact dimensions, installation is straightforward and requires no special tools beyond basic hand tools.

Mechanics, engine builders, and restoration shops depend on this dipstick for TH350/400 firewall-mount applications where OEM or replacement units are unavailable or incompatible with custom installations. If you're converting a vehicle to a Turbo 350 or Turbo 400, swapping transmissions, or servicing an existing classic trans, this part ensures accurate fluid diagnostics every time. Compatibility is specific to firewall-mount configurations—verify your current setup before ordering. This is a must-have for any transmission service kit or engine bay overhaul.
