Product Details

The ATS Diesel Five Star Torque Converter is a premium performance upgrade designed specifically for 2001 to early 2010 GM 6.6L Duramax engines (LB7, LLY, LBZ, and LMM) with Allison 1000 transmissions. Built to handle the demands of daily driving, heavy towing, and increased power applications, this torque converter delivers exceptional reliability and performance improvements over factory units.

Key Features:

  • Patented Viskus Clutch Drive System for maximum efficiency and increased torque capacity
  • Billet cover with patented square flank drive tabs - eliminates the wear common with round tab designs
  • CNC laser-cut clutch plates with proprietary ATS clutch formulation and unique bonding technology ensuring 100% chemical bond
  • 4340 hardened turbine splines provide superior longevity and resistance to engine torsional stress
  • Redesigned spring dampener supports increased torque loads
  • CNC stator with high flow windows and mixed flow design increases oil flow for extreme efficiency
  • Full roller bearing construction between high load areas for reduced friction
  • 4340 CNC-cut pump drive hub locked into impeller housing
  • Plasma welded construction for unsurpassed strength
  • Fully welded turbine and impeller vanes for maximum durability

Performance Benefits:

  • 1300-1500 RPM stall speed optimized for Duramax torque curve
  • 2.4:1 torque multiplication compared to factory 1.25:1 ratio - nearly double the efficiency
  • Improved vehicle response and towing ability
  • Lower transmission operating temperatures
  • Enhanced daily driving performance

Every ATS Five Star Torque Converter is backed by an industry-leading 5-year/500,000-mile warranty, even for competition use. This converter is standard equipment in ATS transmission packages and available individually for transmission rebuilds or upgrades.

Important Note: This is a high-performance torque converter. Installation in a stock transmission is not recommended due to the enhanced stall characteristics, which may cause increased wear on stock clutches and potentially stress the factory flex plate and input shaft. Best results are achieved when paired with upgraded transmission components.

Core Charge: A $400 refundable core charge applies to this product. The core charge will be refunded upon return of your rebuildable core unit.

I was lowering my Mustang and I was looking for a good deal. I looked around online and I found Autoplicity. I was surprised with the prices I saw. I thought it was another one of those fake websites that just take youre money and never respond, so I took the chance and ordered anyway. Dont be fooled by the cheap prices. This place is legit. Fast shipping and the package was packed so neat and looked great when it got here. Buy from these guys if you want to get a good deal. I highly recommend them.

Simple and easy

Great prices, super fast shipping!

Great. Best price

Great prices and fast shipping. Will use this company many more times in the future.

price is great....could use more detailed description of the parts

Please require signature for delivery!

I would definitely recommend Autoplicity. I ordered Thule bike racks (THU-518), and the products arrived in 2 days in perfect condition. Plus the prices (along with free shipping) were the best on the web.

Found what I wanted at a good price.

The Curt Class III Hitch Receiver installation on my vehicle was simple and easy. The hitch is of good quality. I would recommend this product. Autoplicity was prompt with the order process and delivery.
