200r Hi-flow Bottom Feed Filter And Sump Kit on 2040-parts.com

     The 2004R hydraulic system requires a clean and unrestricted supply of transmission oil to keep up with the demands it encounters in performance and racing applications. Specific design requirements are necessary to ensure these demands are met, and begin with the oil sump and oil filter assembly. The oil filter assembly must be completely submerged in fluid, and permit unrestricted access of the transmission fluid to the inlet or pick-up area of the filter. Once the fluid enters the filter, the filtering agent must provide adequate filtration without causing any major restriction to fluid flow. This requires a low restriction filtering agent with an increased surface area.

     The OEM 2004R oil filter assembly does not meet these design requirements. First, the pick-up area is pointing away from the sump, and is therefore not fully submerged in fluid during heavy acceleration.  This allows the pick-up to easily become uncovered, introducing air into the hydraulic system which results in pressure fluctuations and various operating concerns. Second, the entrance to the pick-up area is severely restricted due to the fact that it is squeezed in between the valve body and filter housing. The filter housing itself actually becomes an obstacle to its own fluid inlet due to poor inlet porting.  This severely reduces the fluid volume required to maintain increased line pressures on demand, and results in huge pressure drops during gear changes. Once the fluid has entered the filter, it suffers flow restrictions due to the size and design of the filter element, reducing the overall efficiency of the fluid inlet system.

     The CK Performance Sump Correction Kit includes a high flow SPX 4L60 bottom feed filter assembly. This assembly ensures the pick-up maintains submersion in fluid under all driving conditions, permits unrestricted access of the fluid to the fluid inlet, and provides maximum fluid filtration with minimal flow restriction. See the comparison between the OEM 2004R filter and SPX 4L60 filter in figure. The kit also includes a spacer which must be installed between the oil pan and transmission case to provide the clearance necessary for the larger filter assembly, new mounting hardware, and an insulated fourth gear pressure switch terminal end to eliminate any interference between the connector and filter.
