Perm-Align Trans. Gasket - Ford C4

The Perm-Align Trans. Gasket for Ford C4 transmissions is a precision-engineered seal designed to prevent fluid leakage at the transmission pan interface. Built by MOROSO, a trusted name in automotive gasket technology, this component addresses one of the most common maintenance issues in classic and vintage Ford automatic transmissions. Whether you're rebuilding a C4 after years of service or performing preventive maintenance, a quality transmission pan gasket is non-negotiable for reliable operation and preventing costly fluid loss.

This gasket features a 3/16-inch thickness with a dual-layer rubber and steel construction, engineered to maintain a dependable seal under the dynamic pressures and thermal cycling inherent to automatic transmission operation. The Perm-Align design ensures consistent gasket compression and alignment during installation, reducing the risk of pinching or uneven seating that can compromise the seal. The rubber-to-steel composite provides both flexibility to accommodate minor pan warping and structural rigidity to resist extrusion under elevated transmission fluid pressure. Measuring 10.5 x 10.65 inches, it's sized specifically for C4 pan geometry, ensuring proper fitment without custom trimming.

Technicians and restoration enthusiasts rely on this gasket when servicing C4 transmissions across Ford's broad vehicle lineup, from Mustangs and Broncos to truck applications. Installation is straightforward: clean the pan and case surfaces thoroughly, apply a light bead of gasket sealant if desired, and torque the pan bolts in a cross pattern to manufacturer specifications. This gasket is ideal for transmission fluid changes, pan drop-offs, and complete rebuilds where original sealing integrity must be restored. Proper installation ensures leak-free operation and extends transmission service life, making it an essential consumable for any serious Ford automatic transmission work.
