An increasing number of vehicle manufacturers are using double clutch transmission technology, enabling comfortable gear changes without interruption of traction power, while at the same time reducing fuel consumption and CO2 emissions. Like almost every clutch, the double clutch can also wear out. However, replacement is not possible without special tools. This is because the double clutch is firmly meshed in the gearbox bell and must be removed together with the gearbox. LuK RepSet 2CT clutch kits offer a unique repair solution for dry and wet double clutches. With a LuK kit and the corresponding special tool, repair shops can repair double clutches quickly and professionally. Besides the double clutch, LuK RepSet 2CT kits contain all the precisely matched components in OEM quality which are necessary for the replacement of the respective double clutch system. These include guide sleeves, retaining rings, fixing screws and lever actuators, or engagement levers and engagement bearings. Features to note: * For dry and wet double clutches * Includes all parts needed for the repair * OE quality and perfectly coordinated * Safe mounting due to simple installation instructions * High-quality special tool for the perfect repair

MSD Atomic transmission control modules are designed to adjust the operating parameters of later model electronically controlled 4-speed automatic overdrive transmissions. They're simple to configure with the supplied hand-held monitor--no PC required. You now have access to adjust shift points, adjust torque converter clutch behavior, select different levels of shift firmness, select between auto-shift and manual shift mode, and activate dyno mode to deliver repeatable chassis dyno results. The included hand-held monitor connects to them and can be left in place as a dashboard to monitor the transmission in real time, or can be disconnected when the configuration is complete. Once installed, these modules need only a few basic parameters to complete the initial setup. First, select the type of transmission you are using--all supported transmission types are listed in the menu. Other required fields include the number of engine cylinders, rear-end gear ratio, and tire height. Once this has been completed, you can now start and drive the vehicle, while taking advantage of the advanced setup menu items to dial-in the transmission to your liking. You can feel the results in real-time as a passenger manipulates the parameters and monitors the real-time data. Data available for viewing includes engine speed, vehicle speed, throttle position, transmission fluid temperature, shifter position, and commanded gear. Best of all, the MSD Atomic transmission control modules are available as completely stand-alone units or Brainwave-compatible for the Atomic EFI systems. A transmission controller harness is sold separately.

Lakewood safety bellhousings are designed for maximum performance and durability. They are cut on CNC 5 axis laser cutters rather than plasma cutters to improve finish quality, reduce heat damage and warpage from the plasma cutter, improve speed of manufacture, and make them all exactly the same. All bellhousings feature a scalloped plate on the bottom of the transmission surface made from G70 grade steel (70,000) psi which will help eliminate stripping the transmission bolts. The engine plates are made of H60 grade material and the bells are roto-brated after welding to relive any stresses created from the hydro forming, annealing, or welding process prior to machining and painting. The roto-brating process also closes the metal on the outer surface making them stronger. Ever wonder how the SFI tests bellhousings like these Lakewood safety bellhousings? First, they bolt the bellhousing to a machine with a cast iron flywheel and saw inside it. Then they spin the flywheel, causing the saw to cut through it until it explodes. If the bellhousing can contain the explosion, the bellhousing is approved. These safety bellhousings are a safeguard to minimize the destructive effects of such an explosion. Don't take unnecessary chances with your safety and the safety of innocent bystanders--Lakewood not only provides top-notch products, they also provide peace of mind.

Failure of the intermediate stub shaft and direct drum are almost inevitable when transmissions are pushed to the limit. To maximize durability and improve clutch capacity in heavy-duty/performance vehicles, Sonnax offers Smart-Tech direct clutch drum and shaft kits, the first upgrade to eliminate every critical weakness. Most failures in these units occur where the direct drum and stub shaft connect. Even other aftermarket upgrades that rely on a heavy-duty shaft will sheer in this area under extreme conditions. Unlike two-piece assemblies, the all-in-one Smart-Tech easily handles the highest horsepower/torque levels. The unique one-piece clutch drum with integrated stub shaft is precision machined from high-strength steel to guarantee there are no splines to strip from the drum or weaken the shaft. The shaft itself is significantly thicker and 2 times stronger than the original. Due to its larger diameter, the integrated shaft must be used with the kit's custom, heavy-duty sun gear. Insufficient holding power is another area where many transmissions fall short, but installing thinner aftermarket steels and backing plates to increase clutch capacity isn't ideal. Those components increase clutch pack flex and heat build-up, making them the primary cause of repeat burn-up. To improve both performance and long-term reliability, the Smart-Tech's custom drum and piston hold an OE backing plate and seven OE frictions for 17 percent more clutch capacity than the six-friction stack-up. Sonnax Smart-Tech direct clutch drum and shaft kits feature: * One-piece design that eliminates weak point where drum splines strip and shafts break * Rugged shaft is 50 percent thicker and twice as strong as OE * Custom drum and piston deliver 17 percent more clutch capacity with optimum protection against burn-up * High-strength drum and shaft are precision-machined from hardened 8620 steel * Unique sun gear is precision-machined from 9310, heat-treated steel

The ideal upgrade for performance vehicles with the GM 6L80 or 6L90 transmission, Sonnax extreme-duty 4-5-6 clutch hub and intermediate shaft guarantees maximum protection against shaft breakage. The unique hub design improves oil flow and accepts Powerglide-style frictions to optimize clutch durability. In place of the 2-piece shaft/hub, Sonnax uses a much stronger, one-piece design that eliminates the OE assembly's weak, welded connection. It is custom forged from ultra-high-strength 300M billet steel, and then heat-treated and shot-peened for added durability. This combination of features guards against broken 4-5-6 hubs and the risk of rear splines shearing off.
