Mishimoto Replacement Transmission Oil Cooler for 2003-2007 Dodge Ram 1500/2500/3500 (5.9L Cummins) MMTC-RAM-03TQ
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2003-2007 Dodge Ram 1500, 2500, and 3500 models (5.9L Cummins).
The factory transmission oil cooler in the 2003-2007 Dodge Ram 5.9L Cummins utilizes a liquid-to-liquid design, exchanging heat between the transmission fluid and the engine cooling system. Over time, internal fatigue can cause these units to fail, allowing coolant to mix with transmission fluid. This cross-contamination often leads to catastrophic transmission failure and costly rebuilds.
The Mishimoto Replacement Transmission Oil Cooler (MMTC-RAM-03TQ) offers a direct-fit solution that meets OEM specifications for fit and function. Constructed from durable, corrosion-resistant aluminum, this cooler installs without modifications to protect your drivetrain from premature failure. Each unit includes a new powdercoated bracket and brass fittings for a complete, professional installation.
- Direct-fit OEM replacement requires no modifications
- Liquid-to-liquid cooling design for efficient temperature regulation
- Durable, corrosion-resistant aluminum construction
- Includes powdercoated mounting bracket and brass fittings
- Manufacturer Part Number: MMTC-RAM-03TQ
- Backed by the Mishimoto Lifetime Warranty
