PPE Heavy-Duty Cast Aluminum Transmission Pan

2018–2025 Jeep Wrangler / 2020–2025 Jeep Gladiator

228153520

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 2020 to 2025. Designed to replace the factory stamped steel pan, this premium upgrade enhances transmission cooling and durability for vehicles equipped with the 850RE and 8HP75 transmissions. Excessive heat is a leading cause of transmission wear and failure, and this pan addresses that challenge by increasing fluid capacity and improving heat dissipation, helping to extend the life and reliability of your transmission.

Ideal for off-road enthusiasts, daily drivers, and anyone seeking improved transmission performance and serviceability, the PPE pan offers a robust solution that combines advanced materials and thoughtful engineering to keep your Jeep’s transmission running cooler and longer under demanding conditions.

Key Features:

This heavy-duty transmission pan incorporates several innovative features designed to optimize thermal management and durability:

• Constructed from high-grade A356.0-T6 cast aluminum alloy for superior strength and heat conduction.
• Provides an additional 1.0 quart of transmission fluid capacity, enhancing cooling and lubrication.
• Deep external cooling fins maximize surface area to dissipate heat efficiently during heavy use.
• Integrated internal baffles increase fluid contact with the aluminum surfaces, improving heat transfer and reducing fluid sloshing.
• Cross-bracing structure formed by longitudinal fins and baffles enhances pan rigidity and impact resistance.
• Replaceable transmission filter bolts directly inside the pan, simplifying fluid changes and reducing maintenance costs.
• Equipped with a high-temperature-rated neodymium magnet drain plug to capture ferrous metal particles and protect transmission components.
• Designed for direct bolt-on installation with OEM gasket compatibility, eliminating the need for modifications.

Construction & Design:

The PPE transmission pan is precision cast from aerospace-grade A356.0-T6 aluminum alloy, known for its excellent strength-to-weight ratio and thermal conductivity. This material choice ensures the pan can withstand harsh off-road impacts while effectively transferring heat away from the transmission fluid. The deep external fins are strategically designed to increase the heat-wicking surface area, while also reinforcing the pan’s structural integrity. Internally, the built-in baffles promote consistent fluid flow and heat exchange, preventing fluid starvation and maintaining stable transmission operation under all driving conditions.

Unlike the factory plastic pan with a non-serviceable filter, the PPE pan features a durable metal construction and a replaceable filter element, making routine maintenance more efficient and cost-effective. The drain plug’s powerful neodymium magnet captures microscopic metal debris, providing an additional layer of protection against premature wear.

Installation & Fitment:

The PPE Heavy-Duty Cast Aluminum Transmission Pan is designed for a direct bolt-on fitment to Jeep Wrangler JL models from 2018 through 2025 and Jeep Gladiator JT models from 2020 through 2025. It is compatible with both the 850RE and 8HP75 transmissions found in these vehicles. Installation requires no modifications and uses the OEM-style flat metal gasket with rubber over-mold for a reliable seal. The replaceable filter bolts inside the pan, simplifying fluid service intervals compared to factory pans that require full pan replacement.

For Jeep Wrangler 3.6L V6 applications, PPE offers a variant with machined cooling fins to clear the exhaust cross pipe, ensuring proper fitment without interference.

What's Included:

• Heavy-duty cast aluminum transmission pan
