Predator Stage 4 Allison Transmission

STAGE-4 6-SPEED ALLISON 1000 HD TRANSMISSION
2006-2010 6.6L GM Duramax

The Allison 1000 has been the standard automatic transmission for the Duramax diesel since its inception in 2001.

Predator’s Stage-4 transmission kit will ensure that your Allison transmission can handle up to 850hp at the crank (approx. 680 rwhp) and up to 1,500 ft lbs of torque without damage. This kit is engineered to handle our Duramax conversions that are equipped with multiple high-performance modifications.

Our Stage-4 package utilize the Heavy Duty version of the Allison LCT-1000. While the Allison LCT-1000 for stock applications has been practically bulletproofed, Predators Stage-4 version has been created to go above and beyond. Numerous Proprietary Components and Modifications have gone into its creation.

Saying a lot of R&D has gone into our conversions would be the understatement of the century. Between the engineering team designing parts that our transmission specialists have developed and the thousands of testing hours on thousands of vehicles around the world, no other transmission has been put through the paces like our conversions have. Our built transmissions are designed and produced for what you want out of it and how you are going to drive.

What sets Predator transmissions apart from the rest can be summed up in two words: Innovation & Technology.

 

GM LMM/LBZ  6-Speed Allison LCT-1000 Stage 4 Package.

• C5 includes: 8 (.071″/1.80mm, 115 Teeth) HEG friction plates / 8 (.078″/1.98mm) Kolene steel plates

 

Valve-Body – The valve body, while working with the computer, is essentially the brain of the transmission. It is what routes fluid to particular clutch packs based on which gear your truck needs to be in. Long shift duration promotes premature clutch wear in heavy-duty applications. OEM valve and spring configuration do not allow TCM pressure control strategy to adequately raise clutch pressure and shorten shift duration. Needless to say, this is an important part, so naturally it is in need of improvement. This modification alters the trim valves and springs, resulting in a more responsive clutch pressure.

• A & B Trim Valves & Springs Allison 1000
• Firmer and shorter upshifts
• Firmer TCC engagement
• Improved engine braking on deceleration
• Increased clutch torque capacity

 

Torque Converter – The Predator TripleLok torque converter is engineered with a unique high performance, high-load situations, the torque converter bears the brunt of the engine’s force. Inferior torque converter designs can slip excessively, causing the oil to foam and boil, and the front cover to balloon, even rupture. But Predators TripleLok torque converter was specifically designed to handle the kind of punishment you dish out. Built on our premises in a state-of-the-art transmission facility, our TripleLok torque converters feature triple the clutch material, furnace brazed fins and our own billet aluminum stator design that maximizes low-speed torque. Tested in applications producing up to 1,000 hp and 1500 ft. lbs. of torque, the Predator TripleLok Torque Converter is the ultimate in converter technology.
