Stellar Automotive Group 1000/2000 Series Filter Kit 10-Up fits Allison

Stellar Automotive Group 1000/2000 Series Transmission Filter Kit (2010-Up) – Compatible for Chevrolet & GMC Duramax

Keep your Allison 1000/2000 6-speed transmission performing at its best with this complete 2010-Up filter service kit from Stellar Automotive Group.

This kit includes both the high-flow internal (sump) filter and the external spin-on filter required for full 2010+ service. The updated design features increased filtration surface area for improved fluid circulation and longer life between changes. Regular replacement prevents restricted flow that causes harsh or delayed shifts, overheating, and premature solenoid or clutch wear.

Perfect fit for popular Allison 1000/2000 applications including:

• Chevrolet Silverado 2500HD/3500HD (2010-2024) with 6.6L Duramax
• GMC Sierra 2500HD/3500HD (2010-2024) with 6.6L Duramax
• Chevrolet Express / GMC Savana 2500/3500 vans (2010-2024)

Common issues resolved with fresh filters:

• Delayed or harsh engagement
• Slipping or flare on shifts
• Transmission overheating under load
• Check engine light or limp mode

Easy service – internal filter drops in with pan removal; spin-on replaces like an oil filter. Pan gasket is NOT included (reuse or purchase separately).

Note: All parts are distributed, not designed or manufactured, by Stellar Automotive Group.
