MadJack Diesel has put together the two Allison filters needed for service on your 2006-Up Allison 6 speed transmission. This is a replacement filter kit using Genuine Allison parts for your 2006-Up GM HD pickup truck equipped with the Allison 1000 transmission. The kit includes 1 internal filter Part # 29542833 for a 2006-Up 6 speed Allison 1000 transmission and 1 external spin-on filter part #29539579
**Note The Spin-on filter could be Black or Red depending on what we get from Allison but rest assured they are both Genuine Allison Filters.

Order a Sun Coast Filter Lock to insure your internal filter will not slide down causing cavitation or slide out completely causing complete transmission failure. The Sun Coast shallow filter lock is cheap insurance for a $15,000.00 transmission in your $60,000 dollar truck.
