Sonnax offers high-quality, lightweight aluminum oil pan kit 28801-S for GM Powerglide transmissions. The pan, the lightest on the track, has a wedge shape that allows for two extra quarts of oil capacity without sacrificing ground clearance. Seamless construction and a reinforced pan rail minimize distortion and eliminate leaks and cracks, while the integral baffle ensures proper oil supply during hard acceleration. Threaded fittings are provided for the oil drain and a second fitting for temperature sender or oil chiller return. A magnetic drain plug and nylon sealing washer are included in the kit.

To ensure fluid is picked up under hard acceleration, a special extension must be used with this oil pan to position the filter rearward under the baffle and deeper into the oil. Sonnax extension kits 28801-S09K and 28801-S11K include all the necessary mounting hardware and gaskets. Choose the kit that suits your specific application.
