James Gasket Transmission Gasket And Seal Kit For Harley Touring / Dyna 1999-2006

Premium James Gasket Transmission Gasket & Seal Kit for Harley-Davidson 1999–2006

Reliability is the hallmark of the Twin Cam era, but even the most robust gearboxes can develop leaks over time. The James Gasket Transmission Gasket and Seal Kit is specifically engineered for 1999–2006 Harley-Davidson Touring and Dyna models equipped with the 5-speed transmission. Whether you are dealing with a nagging oil spot on the garage floor or performing a full drivetrain overhaul, this kit provides the high-performance sealing technology required to keep your Twin Cam 88 transmission bone-dry.

Advanced Silicone-Bead Sealing Technology

What makes James Gaskets the industry leader in Harley-Davidson transmission seals is their attention to material science. The gaskets in this kit feature a precision-printed silicone bead on a high-quality micropore base. This design allows the gasket to conform to the microscopic imperfections and heat-induced warping often found in used transmission cases. By creating a secondary mechanical barrier, the silicone bead ensures a 100% leak-proof seal that standard paper gaskets simply cannot match.

Complete Rebuild Kit Contents

Don’t let a missing O-ring stall your project. This JGI-33031-99 series kit is a comprehensive “all-in-one” solution, containing every component necessary for a total transmission reseal. The kit includes:

• Transmission Top Cover Gasket: Featuring silicone beading for a permanent seal against gear oil splash.
• Side Cover Gasket: Precision-cut for the clutch release cover to prevent weeping.
• Main Drive Gear Seal: A heavy-duty, double-lip seal designed to keep transmission fluid away from the primary.
• Quad Seal & Spacer O-Rings: Essential for sealing the mainshaft and preventing common “behind-the-pulley” leaks.
• Shifter Shaft Seal: High-temperature resistant rubber to stop leaks at the selector arm.
• Speedometer Sensor O-Ring: Ensures the electronic sensor port remains airtight and oil-tight.

The James Gasket Quality Standard

For over 40 years, James Gaskets has been the gold standard for American-made motorcycle seals. Their components are engineered to withstand the extreme heat generated by air-cooled V-Twins in heavy traffic and the chemical breakdown caused by modern synthetic gear lubricants. By choosing this Harley transmission seal kit, you are investing in a product that maintains its integrity and torque retention over thousands of miles.

Installation Insights

To achieve professional results, ensure that the transmission case and covers are meticulously cleaned of old gasket residue. This James Gasket kit is designed for a dry installation—no RTV or messy liquid sealants are required, as the silicone beading does the work for you. Always follow the factory-recommended torque sequence and specifications to ensure even pressure distribution across the gasket surfaces.
