Shift Finger Seal

The Jerico shift finger seal (MPN: JER-N6130) is a critical rubber component designed to prevent fluid leakage and contamination at the shifter rod penetration point in Jerico performance transmissions. This seal is engineered for drivers who demand reliability during high-performance driving, drag racing, or extended autocross competition where transmission fluid integrity directly impacts shift quality and clutch engagement consistency. Whether you're rebuilding a transmission after a season of hard use or performing preventative maintenance, this replacement seal ensures your shifter mechanism remains sealed against external contaminants and internal fluid loss.

Manufactured from durable elastomer material, the shift finger seal functions as a dynamic barrier where the shifter rod passes through the transmission housing. The compact design—measuring 3.05 inches in length with a 0.3-inch profile—allows it to fit precisely within the tight tolerances of Jerico transmission casting. Its lightweight construction (0.03 lbs) means zero impact on vehicle performance, while the rubber compound resists mineral oil, synthetic transmission fluid, and thermal cycling typical of track-day environments. Proper sealing at this junction prevents ATF or gear oil migration into the shifter linkage cavity, maintaining consistent shift feel and protecting nearby electrical connectors from fluid saturation.

Mechanics and transmission specialists specify this seal during any Jerico transmission rebuild, overhaul, or when diagnosing unexplained fluid seepage around the shifter rod opening. Installation requires transmission removal and housing disassembly; replacement takes minutes once the old seal is extracted. Compatibility is limited to Jerico transmission applications only—verify your transmission model before ordering. This single-unit seal is sold individually, so order quantity based on the number of transmissions being serviced or maintained on your fleet or race vehicle.
