3" Deep Fabricated Transmission Pan with Filter Extension for GM TH350 / Turbo 350

Upgrade your GM TH350 or Turbo 350 with a 3" deep fabricated aluminum transmission pan that combines increased oil capacity, a built‑in filter extension, and a natural finish for a clean, professional look. Designed by Aeroflow, this pan features a one‑piece billet rail for precise fitment and a secure seal, delivering dependable performance under demanding driving conditions—from spirited street days to endurance track sessions.

Key benefits

• Increased oil capacity with a 3" deep design to promote sustained lubrication and help manage gearbox temperatures during high‑load or high‑RPM operation.
• Filter extension included for enhanced oil filtration and smoother oil flow to the transmission internals.
• Natural finish provides a clean, corrosion‑resistant exterior that looks great and protects against the elements.
• One‑piece billet rail ensures precise fitment and a durable, long‑lasting seal under vibration and heat.
• Dual fittings for versatility – 1 x -6 ORB and 1 x 3/8" NPT enable easy routing for oil lines and optional temperature gauge setups.
• Includes serrated flange bolts for secure, reliable installation.

Why this pan matters for performance and street builds

Heat management is a common bottleneck in manual transmission applications. By increasing oil capacity, the pan helps keep oil temperatures in check during aggressive driving, reducing the risk of thermal breakdown and maintaining consistent shift quality. The filter extension ensures the engine sees clean oil, while the dual fittings offer flexible plumbing options for gauges or remote oil routing, making this pan a smart upgrade for both daily drivers and performance machines alike.
