GM Turbo 400 Deep Transmission Pan

Description

Overview

The GM Turbo 400 Deep Transmission Pan delivers superior strength, reliability, and performance. Built from durable cast aluminium, this deep pan increases transmission fluid capacity, improves cooling efficiency, and extends the lifespan of your GM Turbo 400 automatic transmission. It suits heavy-duty applications, towing, and performance vehicles, while also adding rigidity to the transmission case and maintaining a sleek, functional design.

Unlike standard pressed-steel pans, this upgraded aluminium design dissipates heat more effectively, reducing the risk of transmission overheating under extreme conditions. The added oil capacity provides more consistent lubrication, especially during high-load driving or long-distance towing. For enthusiasts upgrading their driveline, or for those who simply want a more reliable setup for daily use, this pan offers both peace of mind and improved durability.
