Its carbon woven friction type enhances durability and heat resistance, which is critical for maintaining consistent performance in automatic transmissions. The 9.500-inch bolt circle and 10.200-inch diameter ensure compatibility with specific GM transmission assemblies. The 27 spline count and bushing hub type provide a reliable connection to the transmission input shaft, while the 3-pad mounting type secures the converter firmly in place. The pilot diameter of 0.825 inches supports proper alignment during installation. This torque converter does not include a ring gear and is designed to operate within a stall speed range of 1500 to 1750 rpm, suitable for a variety of driving conditions.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicle Applications\u003c\/h2\u003e\u003cp\u003eThis torque converter is compatible with a range of GM vehicles, including but not limited to:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBuick models such as Century, LeSabre, and Regal\u003c\/li\u003e\n\u003cli\u003eChevrolet models including Impala, Malibu, Monte Carlo, and Lumina\u003c\/li\u003e\n\u003cli\u003eOldsmobile models like Cutlass Ciera, Cutlass Supreme, and 88 series\u003c\/li\u003e\n\u003cli\u003ePontiac models such as Grand Am, Grand Prix, and G6\u003c\/li\u003e\n\u003cli\u003eSaturn models including Vue and L-Series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by This Torque Converter\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTransmission slipping or delayed engagement\u003c\/li\u003e\n\u003cli\u003eOverheating due to inefficient torque transfer\u003c\/li\u003e\n\u003cli\u003eShuddering or vibration during lock-up\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy related to torque converter inefficiency\u003c\/li\u003e\n\u003cli\u003eExcessive stall speed causing drivability problems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the torque converter is properly seated on the transmission input shaft before installation to avoid damage.
