This proves to be rather unfortunate for the 6L80, because just as it shares the same design, it also shares the same failures. With increased performance comes the need for increased fluid volume and pressure. When upgrading to a 13 vane pump rotor, the additional vanes, while providing additional volume, inherently can cause a weakness due to the lack of material between the rotor blades. This will almost always cause failure in higher horsepower applications, often times causing catastrophic failure.\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cstrong\u003eThe Intermediate Shaft\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\r\n\u003cp\u003eAn essential upgrade for any hard-working GM 6L80 transmission, Sonnax heavy duty 4-5-6 clutch hub and intermediate shaft (104680-36) guarantees maximum protection against shaft breakage and clutch failure in any vehicle pushing stock components to the limit.\u003c\/p\u003e\r\n\u003cp\u003eIn place of the two-piece shaft\/hub, Sonnax uses a much stronger, one-piece design that eliminates the OE assembly's weak, welded connection.\u003c\/p\u003e\r\n\u003cp\u003eThe one-piece design is custom forged from ultra high-strength 300M billet steel, then heat treated and shot peened for added durability.
