PPE Heavy-Duty Cast Aluminum Transmission Pan

2018–2025 Jeep Wrangler JL/JT & 2020–2025 Jeep Gladiator 3.6L V6, 2.0L Turbo, 3.0L EcoDiesel

Part #: 228153520

Overview

The PPE Heavy-Duty Cast Aluminum Transmission Pan is a premium upgrade designed specifically for Jeep Wrangler JL models from 2018 through 2025 and Jeep Gladiator JT models from 2020 through 2025. Engineered for vehicles equipped with the 850RE and 8HP75 transmissions, this transmission pan replaces the factory stamped steel pan to deliver enhanced cooling, durability, and serviceability. Excessive heat is a primary cause of transmission wear and failure, and this pan combats that by increasing fluid capacity and improving heat dissipation, helping to extend transmission life and reliability.

Ideal for off-road enthusiasts, daily drivers, and anyone who demands improved transmission performance, the PPE pan offers a robust solution that combines advanced materials and thoughtful engineering. It keeps your Jeep’s transmission running cooler and longer, even under the most demanding driving 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 excellent heat conduction.
• Increases transmission fluid capacity by 1.0 quart, enhancing cooling and lubrication.
• Deep external cooling fins maximize surface area to efficiently dissipate heat during heavy use.
• Integrated internal baffles improve fluid contact with aluminum surfaces, boosting heat transfer and reducing fluid sloshing.
• Cross-bracing 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.
• Direct bolt-on installation with OEM gasket compatibility, requiring no 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 superior thermal conductivity. This ensures the pan withstands harsh off-road impacts while effectively transferring heat away from the transmission fluid to maintain optimal operating temperatures.

Deep external fins are strategically designed to increase heat-wicking surface area and reinforce structural integrity. Internally, 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 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.

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. The replaceable filter bolts inside the pan simplify fluid service intervals compared to factory pans that require full pan replacement.
