Product Details

The BD Diesel 1604721 Shift Kit is an advanced transmission upgrade designed specifically for 2006-2008 Chevrolet Silverado and GMC Sierra trucks equipped with the 6.6L Duramax engine and Allison 1000 6-speed automatic transmission. This comprehensive rebuild kit addresses common transmission failures and significantly improves shift quality and durability.

Key Features:

  • Exclusive Smart Trim/Clutch Control valve assemblies for precise shift control
  • C2 clutch piston modification components for increased holding capacity
  • Engineered to handle up to 500 street horsepower
  • Delivers short, crisp, smooth upshifts and kickdowns
  • Improves clutch durability and engagement control

Solves Common Allison 1000 Problems:

  • Transmission slipping into neutral under load
  • 3-4 shift slippage and harsh shifts
  • Burned C2/C3 clutch packs
  • Transmission sticking in one gear
  • No movement after extended parking
  • Loss of pump prime

The C2 clutch is the weakest component in early Allison 1000 transmissions, and this kit specifically reinforces that failure point. Professional installation by an experienced transmission technician is strongly recommended. Includes 90-day parts warranty. This product is legal for sale and use in all 50 states, including California.

Great customer service. Fast order processing. Hassle free transaction.

Thanks

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

Great price and fast shipping! If your looking for quality brands at the best price available!!<br>

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

Great service and communication. Once it was shipped, I was able to track my item. Best price I could find on the internet!! Would definitely do business with anytime.

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!
