PPE Heavy-Duty Cast Aluminum Transmission Pan

2018–2025 Jeep Wrangler / 2021–2023 Jeep Gladiator

228153020

Overview:

The PPE Heavy-Duty Cast Aluminum Transmission Pan is engineered specifically for Jeep Wrangler models from 2018 to 2025 and Jeep Gladiator models from 2021 to 2023. Designed to enhance the durability and cooling efficiency of your vehicle’s transmission, this deep transmission pan significantly improves fluid capacity and heat dissipation. Ideal for off-road enthusiasts and daily drivers alike, it helps extend transmission life by maintaining optimal operating temperatures under demanding conditions.

By increasing fluid volume and improving heat management, this transmission pan reduces the risk of premature wear and transmission failure caused by excessive heat. It is a direct upgrade over the factory stamped steel pan, offering superior strength, cooling performance, and serviceability.

Key Features:

This PPE transmission pan combines advanced engineering and high-quality materials to deliver reliable performance and protection for your Jeep’s transmission:

• Constructed from high-grade A356.0-T6 cast aluminum alloy for exceptional strength and durability
• Deep design provides an additional 2.2 quarts of transmission fluid capacity for improved cooling
• External cooling fins maximize heat dissipation by increasing surface area exposed to airflow
• Built-in internal baffles enhance fluid contact with the pan’s aluminum surfaces, improving heat transfer and reducing fluid sloshing
• Cross-bracing structure formed by longitudinal fins and baffles increases impact resistance and structural rigidity
• Replaceable transmission filter bolts directly inside the pan, simplifying fluid service and reducing maintenance costs
• High-temperature-rated neodymium magnet in the drain plug captures ferrous metal particles to protect transmission components
• Compatible with 850RE and 8HP75 transmissions found in specified Jeep Wrangler and Gladiator models

Construction & Design:

The transmission pan is precision cast from premium A356.0-T6 aluminum alloy, known for its excellent strength-to-weight ratio and thermal conductivity. Its deep profile increases fluid capacity by 2.2 quarts, which helps maintain cooler transmission temperatures during heavy use or towing. The external cooling fins are strategically designed to maximize airflow and heat dissipation, while also reinforcing the pan’s structural integrity.

Inside the pan, integrated baffles improve fluid dynamics by increasing the contact area between the transmission fluid and the aluminum surfaces, enhancing heat transfer. These baffles also minimize fluid movement during acceleration, braking, and cornering, ensuring consistent fluid pickup and stable transmission operation. The combination of external fins and internal baffles creates a robust, cross-braced structure that resists impacts and road debris.

Installation & Fitment:

The PPE Heavy-Duty Cast Aluminum Transmission Pan is a direct fit replacement for the factory stamped steel pan on Jeep Wrangler (2018–2025) and Jeep Gladiator (2021–2023) models equipped with 850RE or 8HP75 transmissions. Installation requires no modifications and uses the existing mounting points and gasket surfaces. The included replaceable filter mounts inside the pan, eliminating the need to discard the entire filter during fluid changes, which simplifies maintenance and reduces costs.

What's Included:

• Heavy-duty cast aluminum deep transmission pan
• Replaceable transmission filter compatible with the pan
• High-temperature neodymium magnet drain plug
• Mounting hardware and gasket
• Installation instructions

Ideal For:

This transmission pan is perfect for Jeep Wrangler and Gladiator owners who demand enhanced transmission cooling and durability. It is especially beneficial for off-road enthusiasts, heavy-duty users, and anyone who frequently tows or drives in high-temperature environments. By improving fluid capacity and heat dissipation, it helps protect your transmission from heat-related wear and extends its service life.
