Sonnax now offers high-quality replacement gear sets for F5 and later E4OD/4R-100 pumps. Two designs are offered: a direct replacement gear set 36438A-01K and an oversized gear set 36438AX-01K. Both Sonnax gear sets are designed to meet or exceed OEM pump gear performance. The Sonnax gears are specially designed to improve the fit and durability of the pump to torque converter interface. The direct replacement gears are designed to fit existing F5 and later pump housings with no machining required. The oversized gears are designed for F5 and later pump housings with excessive wear. The oversized gears allow worn pump housings to be refurbished by machining the pump cavity. Note: In 1995 the E4OD pump was redesigned to utilize pump gears with 10 lobes on the outer gear. Prior to 1995 the outer pump gear had 11 lobes. The pump casting was also revised. Prior to 1995 the pump casting was designated as E9 or F1. Beginning in 1995 the casting designation was changed to F5 and is currently F8. The Sonnax pump gears will work with any F5 or later pumps. The E9 and F1 E4OD pumps suffered from low pump output and should be replaced with an F5 or later model pump.
