GM Turbo 350 Raised Finned Chrome Steel High-Capacity Transmission Pan

• Raised finned design adds surface area for improved transmission fluid cooling

• 3 1/4" depth adds 2 quarts of fluid capacity over a stock-depth TH350 pan

• Fits TH350 automatic transmissions using the matching bolt pattern and sealing rail

• Chrome steel construction resists corrosion; drain plug included for easy service

This raised finned transmission pan increases fluid capacity and cooling surface area on TH350 automatic transmissions, with a 3 1/4" depth adding 2 quarts over a stock-depth pan. Chrome-finished steel construction supports durability and heat dissipation for street, towing, restoration, and performance use. A drain plug is included, threaded at 1/2"-20 for straightforward fluid service without pan removal.

This pan is built for TH350 transmissions using the matching pan bolt pattern, sealing rail, and filter configuration only. Confirm your transmission model, pan depth clearance, and filter pickup length before ordering — a gasket, mounting hardware, and filter extension are not included and should be sourced separately based on your specific application.

Transmission Applications
Fits TH350 automatic transmissions using the correct pan bolt pattern and sealing rail — commonly used in Camaro, Chevelle, Nova, Corvette, and C10/K10/Silverado platforms, as well as Pontiac Firebird and GTO applications running a TH350.

Installation and Clearance
Confirm crossmember and exhaust clearance before installing, since the increased 3 1/4" depth adds more capacity but also more clearance requirement than a stock pan. A gasket, mounting hardware, and filter extension are not included — source these separately, and confirm your transmission's filter pickup length matches the added pan depth so the filter isn't left suspended above the fluid level.

Does this pan include a gasket and mounting hardware?
No — a gasket and mounting hardware are not included. These must be sourced separately for your specific TH350 installation.

Do I need a filter extension with this pan?
A filter extension is not included. Because this pan is deeper than stock, verify whether your transmission's filter pickup requires an extension to maintain the correct pickup position and fluid supply.

Does this pan include a drain plug?
Yes — a 1/2"-20 threaded drain plug is included, allowing transmission fluid to be drained without removing the entire pan.

Will this pan clear my crossmember or exhaust?
Clearance depends on your vehicle's chassis, crossmember, and exhaust routing. This pan measures 3¼" deep, so verify available under-transmission clearance before ordering.

How much extra fluid capacity does this pan add?
This pan adds approximately 2 quarts of fluid capacity compared with a stock-depth TH350 transmission pan.

Is this pan suitable for a towing or performance build?
Yes — the additional 2-quart capacity and finned design can help manage transmission fluid temperatures, making it a useful upgrade for towing, performance, and other higher-heat-load applications.
