Pacific Performance Engineering Automatic Transmission Fluid Thermal Bypass Valve for 2019-2024 Ram 2500/3500 — Billet Aluminium wi

Pacific Performance Engineering’s Automatic Transmission Fluid Thermal Bypass Valve replaces the restrictive factory valve to maximize fluid flow to the cooler and includes a magnetic service plug to capture ferrous debris.

Designed as a direct-fit upgrade for Ram 2500 and 3500 trucks from 2019–2024 with 5.7L, 6.4L gas and 6.7L diesel engines, this billet-aluminum bypass valve addresses a common OEM weak point: restricted internal passages that can fail closed. When the factory valve becomes obstructed by mechanical failure or debris, transmission fluid circulation to the cooler is reduced or stopped, which risks elevated transmission temperatures under heavy loads. The PPE valve restores unobstructed flow, adds a removable neodymium magnet-equipped service plug to trap metal particles, and uses durable materials for long service life.

How does the PPE thermal bypass valve improve transmission cooling?

The PPE valve removes the highly restrictive factory passages, allowing greater volume of ATF to reach the external cooler under normal and heavy-load conditions. Improved flow lowers operating temperature variability and helps the cooling system run as intended during towing or frequent stop-and-go driving.

• Direct-fit replacement of OEM Part# 68359848AD for 2019–2024 Ram 2500/3500
• Billet aluminum construction reduces deformation and wear
• Less internal restriction means higher fluid throughput to the cooler

What is the purpose of the neodymium magnet service plug?

The removable neodymium magnet service plug captures ferrous debris circulating in the transmission fluid before it moves downstream. Because it is removable, you can inspect and clean the plug during routine service to reduce abrasive wear on internal components.

• Strong magnet attracts metal particles from the ATF stream
• O-ring seal preserves system integrity and prevents leaks
• Removable design allows easy inspection and cleaning without removing the valve

Will this part install easily on my Ram 2500/3500?

The PPE valve is engineered as a drop-in replacement for the factory thermal bypass valve, sized and ported to match OEM connections. Installation follows the same mounting points and fittings as the original, so a qualified technician can swap it in with common tools in a short service interval.

• Direct-fit compatibility with specified model years and engine options
• No special adapters required for factory transmission cooler plumbing
• Made to withstand the operating environment of heavy-duty towing tasks

How does this part help with long-term transmission maintenance?

By maximizing cooler flow and trapping ferrous debris, the PPE bypass valve reduces conditions that accelerate component wear. Regular inspection of the magnetic plug during service helps catch metal contamination early so mechanics can address source issues before they escalate.

• Helps maintain lower, more consistent transmission fluid temperatures
• Removable magnet allows routine debris checks during fluid service
• Billet aluminum body resists corrosion and mechanical fatigue

Who is this for: This thermal bypass valve is for owners and technicians of 2019–2024 Ram 2500 and 3500 trucks (5.7L, 6.4L, and 6.7L) who tow frequently, operate in stop-and-go conditions, or want a robust replacement for a restrictive or failing factory valve. It’s also suited to anyone performing preventive maintenance who prefers a serviceable magnetic plug to help reduce internal transmission wear. Note: installation should follow vehicle manufacturer service procedures; this product improves flow and debris capture but does not replace proper diagnostic and maintenance practices.
