Introducing the Tiger Transmissions Heavy-Duty WORKHORSE Rollerized 4R100 Transmission for 1999-2003 Ford Powerstroke 7.3L: Unleash the Power and Reliability You Need
At Tiger Transmissions, we specialize in E4OD and 4R100 transmissions, and our Heavy-Duty WORKHORSE 4R100 Transmission is engineered to deliver exceptional performance and durability for your 1999-2003 Ford Powerstroke 7.3L. Whether you rely on your vehicle for heavy-duty work or demanding off-road adventures, this high-performance transmission is designed to exceed your expectations.
Notable Advancements in Our Upgraded 4R100 Performance Build:
-
Advanced Center Support: We've introduced an innovative "Tripled Support" center support crafted from the robust 954 Bronze material. This support system incorporates a new factory ball bearing and a machined one-piece bushing. This combination provides unparalleled reinforcement to the hub, intermediate shaft, and center support, making it the most robust bushing material available.
-
Indestructible Low Reverse Hub: Our custom-designed low reverse hub has undergone meticulous machining and TIG welding to withstand the most demanding conditions, including high horsepower demands and extreme usage. Unlike conventional hubs that are prone to cracking during strenuous activities like boost launches, heavy hauling, or drag racing, our solution offers permanent durability and reliability. You can see the stark difference between our custom hub and the stock version in the provided images.
-
Enhanced Rollerized Rear Planet: We exclusively utilize steel planets in our build, eliminating the need for thrust washers and significantly enhancing strength. Furthermore, both sides of the six-pinion rear planetary gear are precision machined to accommodate GM Bearings.
-
Upgraded Forward Planet: Our performance build incorporates the sturdiest six-pinion forward planet, sourced from an early 5R110W Transmission. Crafted entirely from steel, it outperforms the stock 4R100 forward planet in terms of strength.
-
Forward Hub Bushing Enhancement: To mitigate friction and heat generation resulting from metal-to-metal contact, we employ precision machining to install a custom bushing within the forward hub. This bushing provides crucial support to the forward planet while reducing wear and heat-related issues.
-
Reinforced Coast Clutch Drum: A common issue in many 4R100 units is a stripped coast clutch drum, typically occurring at the hub and gear interface. To address this vulnerability, we employ TIG welding to create a seamless, solid, one-piece heavy-duty drum, ensuring exceptional durability and reliability.
-
Upgraded Clutch Packs: Our approach involves precision machining of pressure plates within each clutch pack, resulting in an increased number of clutches compared to the stock configuration. This modification significantly enhances clamping power while minimizing slippage. We also incorporate GPZ Clutches, known for their superior holding power, further enhancing overall performance.
