Atesilor Transmission Shift Shaft Seal Kit for Ford C4/C6 — Replacement C7AZ7B498A, Linkage & Throttle Valve Seals

Atesilor's Transmission Shift Shaft Seal Kit replaces C7AZ7B498A to stop leaks at the shift linkage and kickdown on Ford C4 and C6 transmissions.

If you own a classic Ford equipped with a C4 (1964–1986) or C6 (1966 and later) transmission, worn linkage and throttle valve seals are a frequent source of fluid loss and sloppy shifting. This Atesilor kit supplies the seal components needed to renew the shift shaft and kickdown connections, restoring a tight, oil-resistant interface where the linkage and throttle valve meet the transmission case.

How does this kit address common transmission leaks?

The kit replaces the hard-worn seals and small hardware that allow gear oil to seep out around the shift linkage and kickdown. By renewing these sealing points you reduce contamination and maintain proper hydraulic pressure essential for dependable shifting behavior.

• Includes linkage shaft seal and throttle valve seal to stop seepage at critical interfaces
• Grommet and E-clip supplied to secure fittings and prevent movement-related leaks
• Restores factory-style sealing where the linkage penetrates the transmission housing

Will these parts fit my vehicle's transmission?

Yes—this set is designed to match original equipment that fits Ford C-4 transmissions from 1964 through 1986 and C-6 transmissions from 1966 onward. It corresponds to OEM part numbers C7AZ-7B498A and interchange 360726507A, making it a direct replacement for the original components.

• Direct replacement for part numbers C7AZ-7B498A and 360726507A
• Compatible with Ford C4 (1964–1986) and C6 (1966+) transmission models
• Ideal for restorations, rebuilds, and routine maintenance on period vehicles

What materials and durability can I expect from Atesilor seals?

Atesilor uses durable elastomers and corrosion-resistant hardware formulated to withstand the high temperatures and pressures inside an automatic transmission. The materials are selected to resist hardening and cracking over time, offering longer service life than brittle or worn OEM seals.

• High-grade seal compounds resistant to heat and transmission fluids
• Metal grommet and E-clip built for secure mechanical retention
• Designed to hold up under repeated cycles and long-term use

How difficult is installation and what should I prepare?

Installation is straightforward for anyone familiar with transmission linkage work: you remove the old seals, clean the area, and press or seat the new components in place. Basic hand tools and a clean workspace are usually sufficient, though access may require raising the vehicle safely and detaching linkages.

• Typical tools: pliers, seal driver or socket, screwdrivers, and a torque wrench if reattaching components
• Allow time to drain and catch any residual fluid, then clean seal surfaces before fitting
• Follow vehicle-specific service manual steps for best results and safety

Who is this kit for: Atesilor's Transmission Shift Shaft Seal Kit is aimed at mechanics, restoration enthusiasts, and DIY owners working on classic Fords with C4 or C6 transmissions who need an OEM-equivalent replacement for leaking linkage and kickdown seals. It suits anyone performing a transmission rebuild, preventive maintenance, or addressing visible leaks around the shift linkage.

Key specifications:

• Manufacturer Part Number: C7AZ7B498A
• Interchange Part Number: 360726507A
• Kit Type: Linkage & Throttle Valve Seal Kit
• Installation Location: Shift linkage and kickdown connections
• Compatibility: Ford C4 (1964–1986), Ford C6 (1966+)

Replacing these small but essential seals helps prevent fluid loss, preserves transmission life, and restores crisper shift feel—making it a high-value maintenance task for older Ford automatic transmissions.
