JW Performance Transmissions has steadily expanded their core transmission business with product innovations such as "The Wheel", "Ultra-Bell", and the "Ultra-Case". J.W.'s founder John Winters Sr. continues to improve the company product development and testing of new products. This development shows in every highly engineered J.W. product.
The second generation of this family owned and operated company, which is continuing with the same spirit and goals that John Winters Sr. started the company with in 1976, will lead this company into the future. With small company values, combined with leading technology, you get the best product available. JW Performance Transmissions builds a full line of performance and race transmissions including the GM Powerglide, GM TH-350, GM TH-400, Ford C-6, Ford C-4, Chrysler 904 and 727 and more. Additionally the company produces SFI flexplates, SFI transmission cases, SFI Bell housings, conversion adapters and a full array of transmission components such as input shafts, bands, pans etc.
The other core component of JW Perrformance transmissions is their torque converter building capability. They build them from the ground up specifically for your car. From a 2500 RPM stall street converter to a 2500 HP 10 inch bolt together converter and anything in between, JW is a leader in the market.
