Best 4R75E Rebuild Kits
The 4R75E is a highly reliable transmission. It is a successor of the 4R70W and features a turbine speed sensor and a more powerful microprocessor. These are significant improvements that make it even lighter than the 4R70W.
However, when your 4R75E starts to break down, you can choose two options. You can have it refurbished or remanufactured.
Refurbishing mostly means cleaning and using the same OEM (original equipment) parts, while remanufacturing means installing new, aftermarket parts from special rebuild kits.
This article aims to help you choose one of the best 4R75E rebuild kits so that you can completely remanufacture your transmission and prolong its longevity.
Best 4R75E Rebuild Kits
We will start our list with two 4R75E rebuild kits from Raybestos.
Ford 4R75E Master Rebuild Kit
This is the simpler master rebuild kit for the 4R75E Ford transmission, and it includes components like a complete set of friction clutch plates and an overhaul set of gaskets and seals.
What’s notable about this master rebuild kit are the Raybestos friction clutch plates. They are designed to deliver superior performance and be more durable than OEM parts.
The hybrid technology used to manufacture these plates, combined with their unique groove pattern, make them highly durable and long-lasting. This also increases the transmission’s torque output and heat resistance.
The price of this kit is around $300, plus additional expenses. It’s available on Amazon here.
Ford 4R75E Super Rebuild Kit
The second kit by Raybestos is a Super Rebuild Kit. It includes more parts than the previous one and is a kit for a complete overhaul of the 4R75E transmission.
