Muldoon's Performance Transmission's Full Manual Valve Body – High-Performance Automatic to Manual Conversion

Upgrade your Dodge Ram, 47RE, or 48RE transmission with the MPT Full Manual Valve Body, engineered for consistent, high-performance manual shifting. Designed for reliability and precision, this valve body is ideal for heavy-duty trucks and high-pressure applications.

Key Features:

• Locked 4-3 Downshift – Provides predictable downshifts under load

• No Governor Pressure Solenoids/Transducers Required – Ensures more consistent shifts, even on high-pressure valve bodies

• Valve Body Pressure Adjustment – Includes detailed instructions and guidelines

• Tested OD/TCC Solenoid – Fully verified for optimal performance

• Custom Laser-Cut Separator Plates – Precision-engineered for accurate flow and durability

• Flat-Sanded Castings – Improves sealing and reliability

• Ultrasonic Cleaning of Castings – Ensures all components are free of contaminants

• Thread Inspection and Repair – All threads checked and repaired if necessary

• Vacuum-Checked Bores – Repaired for excessive wear to maintain optimal performance

• Static Line Pressure Set – 150 PSI overall, 190 PSI in 4th/TCC lockup; no external line pressure adjustments required

Core Requirements:

• We accept 47 or 48 valve bodies as cores.

• If your valve body has been modified with anything other than a Transgo shift kit, please email images of your core.

• We do NOT accept BD, ATS, or Sonnax valve bodies as cores.

Important Notes:

• MPT manual valve bodies are not shipped with 48RE rooster combs. If installing in a 48RE, retain your existing rooster comb and swap it when you receive your manual valve body.

• If you select the “I will send my core in ahead of time” option, MPT will not ship your manual valve body until we receive your acceptable core.

Enhance your truck’s transmission with a high-performance, reliable MPT manual valve body for smooth, precise shifts, and maximum control. Perfect for Dodge Ram 47RE and 48RE owners looking for a professional manual conversion solution.
