This part is a Genuine Allison OEM replacement part. If you have a GM Kodiak or Top Kick or an aftermarket deep pan such as the PPE, Allison Stamped Steel or a Mag-Hytec Deep Pan this filter is the replacement for your application. The Allison internal filters were redesigned recently and have new part numbers. The Allison Part Number (New Number) 29542924 (Old Number) 29537966 will fit all Kodiak/Top Kick factory applications and aftermarket deep pans installed on the GMC/Chevy Duramax Diesel 6.6L and 8.1L gas engine with Allison 1000 Transmission.
Order a Sun Coast Filter Lock to insure your deep pan filter will not slide down causing cavitation or slide out completely causing complete transmission failure. The Sun Coast deep filter lock is cheap insurance for a $15,000 transmission in your $50,000 dollar truck.
