Product Description
Genuine GM 24219390 O-Ring Seal
Fits Input / Turbine Shaft on 4L80 E • 6L80 • 6L90 • 8L90 Automatic Transmissions
The Genuine GM 24219390 O-Ring Seal is engineered to maintain critical hydraulic pressure for the torque-converter clutch (TCC) lockup circuit inside your transmission. Aged, heat-hardened, or damaged seals can cause slow or incomplete lockup engagement, leading to excessive converter clutch wear. This OE replacement provides the exact fit and material quality required to restore proper pressure sealing and long-term reliability—far superior to lower-grade aftermarket alternatives.
