Alto Red Eagle Power Packs for 6L80E Transmissions

The new 6L80E / 6L90E Alto Red Eagle Power Packs are here. The 3-5 direct clutch has 14 single sided clutches and the 4-5-6 overdrive clutch has 18 single sided clutches. These are the two weak points in the 6L80E transmission. This is a 75% larger clutch apply area in the 3-5 clutch and a 50% larger clutch apply area in the 4-5-6 clutch. Nobody else has these Power Packs. Call Blake at 1-888-2012066 for information and pricing.

PATC is proud to present to you our new 6L80E power packs. Just as we revolutionized the industry with our 700R4 / 4l60E products we are now proud to bring you the next generation in GM performance. We have been working extensively on the new 6L80E transmission in conjunction with ALTO products and now bring to you our latest creation. The new power packs feature a state of the art friction material that has a higher friction coefficient that is unparalleled to any other clutch disc on the market. We have increase the total clutch apply area by adding more friction clutches to the power pack as well. Higher clutch count = higher apply area. Combined with higher friction surface area this decreases slippage which is a major factor in contributing to premature failure in high performance applications. In developing these clutches we also have introduced thermography, (which is the usage of thermal resolution) to produce a state of the art steel material that not only provides a unmatched mating surface for the clutch but also provides a metal that will not cone or warp under extreme stress.

6L80E / 6L90E 3-5 Clutch Instructions: For the 3-5 clutch to work correctly in a performance application you must have .070" to .072" stack up clearance. To obtain this clearance you will need to machine .025" to .035" off of the 3-5 clutch backing plate.

PATC is proud to bring you our newest 6L80E transmission improvement. When the 6L80E / 6L90E was first released we knew the possibilities were endless. We actually made the decision to purchase 2 new test vehicles to help us develop this transmission, a 2011 AWD GMC Denali and a 2012 Camano 2SS. There are 8 major improvements in our new power hub versus the factory hub. We spared no expense on this one. We started our design by eliminating the clutch hub dampener. This increased the contact area between the shaft and hub by 300%. We then designed our shaft out of 300M billet alloy steel, proceeded by heat treatment for added strength. This also ensures that the splines on the shaft have no chance of twisting off or breaking with heavy shock loads. This makes it ideal for hard launches at the track on big boost motors. The hub is made from 4340 HTSR (Heat Treated Stress Relieved) steel, we then have a Zinc Chromate coating applied for increased durability. This is where things start getting really sweet. We have a redesigned Torrington thrust bearing that has 100% more roller bearings than the factory one. There are also 150% more oil lubes holes on the hub itself. The inside clutch hub corner has a very large radius machined in versus the factory 90 degree angle. What make this really sweet though is the fact we have machined this one piece billet steel hub to accept a Powerglide clutch. This really opened the door for already race proven clutch material and set-ups that we know works, and yes we have developed a Power Pack for this that is turning the world on it's ear yet again. We have the most complete and well designed solutions for this shaft and clutches on the market. This was engineered in collaboration with engineers from 2 different race industry manufactures. We know this works and have the scientific evidence to back it up.

By eliminating the clutch hub dampener. This increased our contact area between the shaft and hub by 300%. We designed our shaft out of 300M billet alloy steel, proceeded by heat treatment for added strength. Heat treated for added strength after the manufacturing process. The hub was made from 4340 HTSR (Heat Treated Stress Relieved) steel, we then have a Zinc Chromate coating applied for increased durability. We redesigned the Torrington thrust bearing to have 200% more roller bearings than the factory one. 50% more oil lubes holes on the hub itself. Machined this one piece billet steel hub to accept a Powerglide clutch.

 Our newest design to the 4-5-6 Power Pack is no accident. This is an evolution of over 4 years of research and development with a 8 man design team consisting of 3 engineers, and 5 industry leading R&D Technicians with over 100 years combined transmission experience. In our design process we have used and tested this 6L80E Power Pack using 4 completely different friction materials, 6 different thickness steels, and used 3 different clutch counts. This research was done both in house on our transmission dyno and on our 2 test vehicles and in conjunction with several different race teams. In our test vehicles we experimented with different approaches and set-ups for both the AWD Denali and the Chevy Camaro. We did this to observe the differences in wear rates between a 3700lb car and a 6400lb SUV. Fast forward 2 years and many, many gallons of transmission fluid later we have a product that has been tested with several race teams in both of our test vehicles and on our dyno. This combo does not cone when increased pressures are applied and holds extremely well. We have entertained in this process changing out the apply piston for a wider base, which there are a few attempting this, but in investigating this our engineer's found that you are sacrificing the amount of release oil than can be applied, because of the smaller surface area. In the high performance transmission world everyone knows the release is just as important as the apply. You want no drag during shift change. In the picture below you can see the new clutch plate is 50% wider than the the stock size 6L80E clutch plate.

We experimented with many types of clutch material over the past three years. But when teardown time came it was obvious that the Alto Red Eagle friction material provided better wear characteristics than this generation of the Carbonite friction material. The deciding factor was in the final stage of thermograph testing that indicated a slightly lower temperature at sustained high RPM's. This redesigned Power Pack will hold 8 frictions and 7 thick heat treated Kolene steels. We know if you go too thin on the steels they will not be able to dissipate the heat and warp up.

On the left we have a picture of the stock size 4-5-6 clutch plate versus the Powerglide clutch below it. You can see the larger surface area the Powerglide clutch will yield us. There's another benefit with this clutch. It's a 2 sided friction clutch that has excellent heat dissipation properties.

" 6L80 / 6L90 Phoenix " 1,200 RWHP RATED

No excuses, no exceptions, no stone left unturned. This "Power Glide" powered transmission is the most advanced 6L80 / 6L90 transmission on the market today. This transmission comes with our Full Billet 10 1/2 inch torque converter with a very large billet clutch apply piston. The apply piston is covered in double woven Kevlar clutch material. This is mated to the billet converter housing giving you unmatched apply area and absolutely no piston deflection when higher apply pressure is ramped up. We did not stop there with this converter, we also have developed 4 different stators with different fin counts and fin angles. These stators allow us to change the fluid dynamics within the converter, giving unmatched efficiency at part throttle and insane torque multiplication at wide open throttle. These converters are custom built in house here @ PATC. Also included is the #6L80PMK " Phoenix Master Kit ". This is the complete solution for your 6L80 / 6L90 transmission. We start off with our special made #6L80MK module kit that includes our Alto Red Eagle clutches and custom spec'd Kolene steels. These steels are made from 4140 HTSR steel and Kolene coated for increased rigidity. These improved steels allow more aggressive pressure ramps and will eliminated "coning" as seen in so many other transmission failures. We also add our 3-5-R Alto Red Eagle power pack. We machine the apply piston to allow more clutches in this drum. The "Phoenix" transmission also comes with our Powerglide Billet clutch hub and shaft. This is the final solution for you 4-5-6 clutch needs. We use a PATC custom machined billet hub and shaft that is cut to accept our PATC custom Powerglide 6l80 / 6L90 power pack. This Power Pack will come with 8 full thickness Alto Red Eagle Powerglide clutches, 7 HTSR steels, special thick .160" base plate and a custom machined 4-5-6 piston. We have removed the bottom factory wave plate to increase clutch apply surface area. The removal of the wave plate will increase "apply feel", but this transmission is not for the light of heart. To eliminate any chance of "coning" we have designed a very thick .160 pressure apply plate that is also made from 4140 HTSR steel. PATC also replaces the factory hubs with TIG welded and Cryogenically treated (#1TWS) shafts and hubs. The pump and valve body are also gone through and receive our own custom modifications to improve fluid dynamics. We replace the pump bushing with a Teflon coated pump bushing and install a Jumbo filter to complete your build. The stock factory pump rotor is replaced with the new PATC Billet steel pump rotor. The stock pump rotor has been known to explode with very fast acceleration due to sudden centrifugal force shock. Cost $6,275.00. Custom tuning must be performed to the TCM to accommodate the new parts. Call Blake @ 1-888-2012066 for tuning and transmission details.
