PPE Heavy-Duty Cast Aluminum Transmission Pan

2018–2025 Jeep Wrangler / 2021–2025 Jeep Gladiator 2.0L Turbo, 3.0L EcoDiesel, 3.6L V6, 6.4L 392 Engines

Part #: 228153420

Overview

The PPE Heavy-Duty Cast Aluminum Transmission Pan is a precision-engineered upgrade designed specifically for Jeep Wrangler models from 2018 through 2025 and Jeep Gladiator models from 2021 to 2025. Compatible with 2.0L Turbo, 3.0L EcoDiesel, 3.6L V6, and 6.4L 392 engines paired with 850RE or 8HP75 transmissions, this transmission pan addresses the critical need for improved cooling and durability under demanding driving conditions.

By increasing transmission fluid capacity and enhancing heat dissipation, the PPE pan helps maintain optimal operating temperatures, reducing premature wear caused by fluid breakdown and insufficient lubrication. This makes it an essential upgrade for off-road enthusiasts, heavy haulers, and daily drivers who want to extend the life and reliability of their transmission.

Key Features

Designed to deliver superior transmission protection and ease of maintenance, the PPE Heavy-Duty Cast Aluminum Transmission Pan offers the following key features:

• Constructed from high-grade A356.0-T6 cast aluminum for exceptional strength and thermal conductivity
• Increases transmission fluid capacity by 1.0 quart to improve cooling efficiency and thermal management
• Deep external cooling fins maximize surface area for rapid heat dissipation while maintaining proper ground clearance
• Integrated internal baffles enhance fluid contact with aluminum surfaces, boosting heat transfer and reducing fluid sloshing
• Cross-bracing structure formed by longitudinal fins and baffles increases impact resistance and structural rigidity
• Replaceable transmission filter mounts directly inside the pan for simplified fluid changes and reduced maintenance costs
• Magnetic drain plug equipped with a high-temperature-rated neodymium magnet captures ferrous metal particles to protect transmission components
• Direct replacement for OEM stamped steel pans on Jeep Wrangler and Gladiator 850RE and 8HP75 transmissions

Construction & Design

The transmission pan is precision cast from premium A356.0-T6 aluminum alloy, known for its excellent strength-to-weight ratio and superior heat conduction. This robust material choice ensures the pan withstands off-road impacts and harsh driving environments while efficiently dissipating heat through its deep, strategically designed cooling fins.

Internal baffles are engineered to increase fluid turbulence and maximize contact with the aluminum surfaces, improving heat transfer and preventing fluid starvation during aggressive driving or steep inclines. The pan’s cross-bracing design distributes mechanical loads evenly, enhancing durability and resistance to deformation over time.

Special machining on the external fins provides clearance for exhaust components, particularly in 3.6L V6 applications, ensuring proper fitment without sacrificing ground clearance or performance.

Installation & Fitment

The PPE Heavy-Duty Cast Aluminum Transmission Pan is a direct bolt-on replacement for the factory stamped steel pan on 2018–2025 Jeep Wrangler and 2021–2025 Jeep Gladiator models equipped with 850RE or 8HP75 transmissions. Installation requires no modifications and uses OEM gaskets and hardware for a perfect fit.

The included replaceable transmission filter mounts inside the pan, eliminating the need to discard the entire filter during fluid changes. This design simplifies maintenance and reduces long-term service costs, making it ideal for owners who perform regular transmission upkeep.

What's Included
