Stef's Fabricated Aluminum Transmission Pan - GM Powerglide
Stef's Fabricated Aluminum Transmission Pan - GM Powerglide 4005
Wheel stands and hard launches are enemies of the racing transmission. Loss of fluid to the pickup creates a pressure drop to clutches, causing inconsistent times and increased fluid temperature which leads to eventual transmission and converter failure.
STEFS colaborated with various class racers on how to improve transmission pan design to prevent the premature failure of automatic transmissions. STEFS increased the depth and added baffling to the stock pan for enhanced fluid control. The results produced a winning combination.
STEFS transmission pans are substantially lighter than stock steel, aftermarket steel, and/or cast aluminum pans. An unanticipated benefit of the pans construction from .090 aluminum is that the pan dissipates fluid temperature quicker then any other type of pan.
Each pan comes complete with mounting hardware, magnetic drain plug, and filter extension when applicable.Features:
While STEF'S Fabrication Specialties offers many oil pan types and designs for most forms of motorsports, they all share one thing in common; method of manufacture. All STEF'S oil pans are fixture assembled and 100% heli-arc welded inside and out to produce a fully fabricated product. Unlike some brands which use OEM, IMPORTED, or OEM look-a-like dissimilar material thickness cores as their foundation, STEF'S Fabrication Specialties method incorporates true finish and fitment component construction, offering matched material thickness for uniform weld penetration and the absence of mismatch or excessive material overlap which can trap dirt and debris during manufacture and operation. All STEF'S oil pans, whether constructed of steel or .090" thick aluminum, offer reinforced pan rail and seal areas that are all block fitted prior to leak testing. For the circle track, marine, and/or any other type of steel oil pan,an additional internal welding process utilizes a special asoft-wirea welding process. This concept is considerably more forgiving to vibrational movement and is more crack resistant than other processes like MIG welding used by other oil pan manufacturers. It is STEF's Fabrication Specialties commitment to produce only the finest oil system related products for their customers. . . .That's a promise!!
