TH400 SONNAX SELECTOR SHAFT KIT WITH NUTS AND SEAL T400 TURBO 400 38511-05K

The manual shift shafts in GM TH400 units become corroded in harsh environments and are not suitable for reuse, especially in remanufacturing. The Sonnax manual shift shaft kit 38511-05K is a direct replacement designed specifically to match the TH400 shaft geometry, which minimizes the amount of shift linkage adjustment necessary. The Sonnax manual shift shaft and fasteners have been yellow zinc plated to maximize corrosion resistance from road salt and other environmental contaminants. The flange face of the nuts is serrated for better holding capacity.
