CD4E 15-Piece Transmission Steel Plate Kit

The CD4E Steel Plate Kit is a 15-piece transmission hard-parts replacement set designed for rebuilding and repairing Ford CD4E four-speed automatic transmissions. The kit contains steel clutch plates used together with the corresponding friction plates inside the CD4E clutch assemblies. During a transmission rebuild, worn, overheated or distorted steel plates should be inspected carefully because their condition directly affects clutch clearance, heat transfer and clutch pack operation.

This 15-piece steel plate kit is intended for professional transmission rebuilders, repair workshops, parts distributors and wholesale customers. CD4E transmissions were used across a range of Ford, Mazda and Mercury applications, including vehicles such as Ford Escape, Ford Mondeo, Ford Contour, Mazda 626, Mazda MX-6, Mazda Tribute, Mercury Cougar and Mercury Mystique. Exact clutch-plate configuration can vary by transmission year and build, so the transmission model and original plate specifications should be confirmed before ordering.

CD4E 15-Piece Steel Plate Kit

The CD4E 15-Piece Steel Plate Kit provides the steel members of the clutch packs required during transmission rebuilding. Steel plates work between friction plates and provide the reaction surfaces needed for the clutch packs to apply and release correctly.

A complete steel kit may contain plates with different outside diameters, inside diameters, tooth counts and thicknesses because different CD4E clutch groups use different plate designs. For this reason, the quantity of 15 pieces alone should not be treated as a universal specification for every CD4E transmission. The correct set should match the application and the internal clutch configuration.

CD4E Transmission Repair Application

The CD4E is a four-speed front-wheel-drive automatic transmission with electronic controls. Its internal clutch assemblies use both friction and steel plates to transfer torque through the transmission. Ford service information identifies separate steel clutch plates in the low/reverse clutch and other clutch assemblies.

During overhaul work, technicians normally inspect the steel plates for blue discoloration, glazing, warping, scoring, excessive wear and loss of flatness. A damaged steel plate can change clutch pack clearance and may contribute to poor engagement, slipping or abnormal shift behavior after rebuilding.

Replacing the steel plates as a matched set can help provide consistent clutch-pack geometry when rebuilding a worn CD4E transmission.

Steel Plate Design and Fitment

CD4E steel plates are not all identical. Different clutch positions can use different thicknesses, tooth counts and dimensions. Aftermarket transmission catalogs list separate CD4E steel components for direct, forward, reverse, coast and low/reverse clutch applications.

Some catalog references identify CD4E steel components by dimensions and clutch position rather than by one universal OE number. This is important when ordering replacement parts because a visually similar plate may have a different thickness or internal spline arrangement.

For wholesale customers, we recommend confirming the transmission model, production year, clutch position and original plate dimensions when the application is uncertain.

Professional Transmission Rebuilding

The CD4E 15-Piece Steel Plate Kit is suitable for transmission overhaul and rebuild operations where the clutch packs are being serviced. Steel plates should be installed with the correct friction plates, pressure plates, snap rings and selective components according to the transmission service procedure.

Before assembly, technicians should clean all clutch components and check the drum, piston, seals and clutch pack surfaces. Correct clutch clearance is important for reliable operation. If the transmission uses selective steel or spacer components, the technician should follow the appropriate measurement and adjustment procedure rather than assuming that every rebuild uses the same stack height.

Using new steel plates together with a suitable friction kit and overhaul kit can provide a practical solution for rebuilding a worn CD4E transmission.

We also supply transmission friction plate kits, overhaul kits, bonded piston kits, filters, sealing components and other automatic transmission repair parts. When rebuilding a CD4E unit, customers can combine the steel plate kit with the matching friction kit and overhaul components according to the required repair scope.

For professional workshops and distributors, supplying the steel kit together with other CD4E rebuild components can simplify parts sourcing and help maintain consistent component matching.

CD4E Steel Plate Kit Wholesale Supply

We supply CD4E transmission steel plate kits for professional rebuilders, distributors and wholesalers worldwide. The 15-piece configuration is suitable for applications requiring this specific steel-plate combination, but exact fitment should be confirmed before shipment.

Please contact us with the transmission model, vehicle information, original part number or photos of the old clutch plates if available. Our team can help confirm the application, available configuration, packaging and wholesale quotation before order placement.
