GM 6L80 and 6L90 transmissions often suffer failure of the 4-5-6 clutch assembly due to flexing and bowing of the backing plate (coning)—especially when your clutch-apply pressures exceed OE specifications. Sonnax clutch backing plates are designed to minimize flexing/bowing when the clutch is applied, drastically reducing the likelihood of clutch plate distortion. Their stiffer backing plate design outperforms OE and aftermarket plates.

XClutch Stage 1 clutch kits offer a variety of performance upgrades for both street and track applications. They are designed in-house and normally utilize a single plate organic, ceramic, or carbon friction disc along with an upgraded factory-style pressure plate. XClutch kits utilize a similar mechanism to the factory clutch, making them ideal enhancements for most vehicles with low to mid-level performance modifications. Stage 1 clutch kits are available in three distinct performance clutch packages—sprung, rigid solid, and steel-backed organic. Features and benefits of each: * 1A sprung organic—this range has been specifically designed for street vehicles that have minor engine and general performance modifications. These kits offer a sprung organic friction disc that allows for great drivability, while offering improved clamping force through the use of a performance pressure plate. * 1G rigid solid organic—with a rigid center version of the organic disc, this range is ideal for street vehicles and light track use. These kits are often available with a lightweight alloy pressure plate and performance flywheel. * 1T steel-backed organic--this range offers a higher burst strength by bonding the organic friction material directly to a steel backing plate. These kits are ideal for high performance vehicles used on the street with occasional track use.

Tremec introduces the Magnum-F 6-speed manual transmissions for fourth-generation Camaros and Firebirds. Designed to replace T-56 transmissions in 1998-2002 GM F-body cars, the Magnum-F leverages Tremec's pervasive TR-6060/Magnum architecture in order to provide fourth-gen enthusiasts significantly improved performance and relief from a shrinking pool of quality T-56 replacement parts. Born in the vacuum created by the release of the original T-56 Magnum (now known simply as 'Magnum') back in 2009, the Magnum-F fills a longstanding void in the overall Magnum line with regard to shifter locations—addressing not only LS1-powered '98-'02 F-bodies, but several other applications that utilize a similar shifter position. Beneficiaries include third-generation F-bodies, LT1-powered fourth-gens, LS-swapped late models of all varieties, and sport compact applications such as A80 Supras, FD RX-7s, and more! Where the original Magnum shifter locations may prove too far forward, and the extended length Magnum XL's too far back, the Magnum-F's in-between position often proves to be just right. Inside, the Magnum-F benefits from the same durable componentry found in many of today's hardest hitting OEM muscle and sports cars. Over the T-56, the Magnum-F transmissions boast increased face-width on all gears, a robust combination of double and triple cone synchronizers, enhanced webbing in the main case, provisions for a cooler circuit, and more! Tremec also took the opportunity to upgrade the shifter to an isolator-type unit, like that found on its Magnum XL. The shifter reduces in-cabin noise and vibrations, while at the same time providing the precise and communicative shift feel that all Magnums are known for. And, like all Tremec aftermarket transmissions, the Magnum-F is made from 100 percent brand-new OEM-quality content. Models with different gear ratios are available. Additional notes: * Close Ratio version for high performance street and road racing * 700 lbs.-ft. of torque capacity * Reasonably light at 135 lbs. dry * Multiple shifter locations and dual speedo pickups for unmatched versatility * Choice of two different gear ratio sets with unique double overdrive ratios * Incredibly short, extremely low-effort shift throws, with crisp, precise engagement * Modern OE supercar technology for the ultimate pro-tourers, road-racers, and more

RevMax billet high performance towing/HD valve bodies for a variety of applications, including many Dodge and Ram trucks from the early 2000s and up. The V2.0 is 1 in. thick, but this new version has precision cutouts that allow the use of a stock filter and pan. Unlike other designs, full depth worm tracks in crucial circuits are included. Other competing designs have only a .190 in. deep worm track in several critical circuits. One restricted circuit is the combined vent track, responsible for all venting operations and in particular the problematic SSV valve. The next restricted circuit is the torque converter clutch signal circuit. Restrictions in this circuit create all kinds of torque converter related concerns, including dragging when coming to a stop, overheating, soft or harsh TCC apply or release, and back feed issues resulting in P1776 and P0871 trouble codes. Both the original and V2.0 have nearly full depth worm tracks in these areas which eliminate problem issues! The V2.0 plate will work with ANY aftermarket transmission pan, as well as with stock transmission pans. There is no need to alter any part of the pan or use special filters. Just install it like you would a stock channel plate and go. Order the model recommended for your year/make and transmission application. The RevMax 68RFE V2.0 ZeroFlex billet valve body features the following: * 6061 billet aluminum construction * Deep critical worm tracks * .0003 flatness across the entire plate. The only truly flat billet channel plate! * Micro-polished worm track surface. There are no visible or perceptible machining marks or stepovers. This ensures no chance of any leaking due to machining marks * Large radius machining on the filter cutout increases rigidity yet allows the use of a stock filter assembly * Angle milled step downs increase rigidity in problematic flexing areas * Ability to run up to 325 psi of line pressure without any warpage! (transmission tuning, TCM upgrade or pressure box is needed) * No pump modifications required for up to 250 psi * Proprietary worm track layout * Shortened shift times for crisp, clean shifts * Upgraded valve body to case seals * Billet steel SSV solenoid switch valve and end plugs * Revmax triple double 3/2 billet accumulator pistons with dual seals * Upgraded grade 8 custom fasteners * Upgraded steel accumulator housing plate that is 3x thicker than stock * RevMax proprietary accumulator springs for improved 3-4 shift feel * RevMax proprietary separator plate with the bonded gasket that eliminates cross leaks and warpage issues * Revmax proprietary upgrades * Mounting surface verified and flat filed * Threads checked and repaired if needed * Computerized testing on state-of-the-art $125k valve body test machines

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

In 1989, Dodge and Cummins came together to make a diesel light truck for the ages. From 1989-92, Dodge coupled the Cummins to a Gertrag 5-speed manual transmission. Now, with the use of Advance Adapters Mopar NV4500 transmission bellhousing adapters, you can upgrade these earlier models to the NV4500. The NV4500 5-speed was used in heavy-duty Dodge trucks for the 1993-2007 model years, making it considerably easier to find donors over the Gertrag. These adapters feature a new 356 T-6 aluminum bellhousing and a new pilot bearing for both 2WD and 4WD applications. In addition, 4WD kits include a transfer case shift bracket and crossmember mount. To make things easier and less expensive for the consumer, these bellhousings utilize the stock clutch arm, release bearing, and slave cylinder. Modifications will be required to the NV4500 prior to assembly. The bearing retainer must be removed from the front and shortened to 4.297 in. long to prevent any interference with the hub on the clutch disk. Test-fit the bellhousing to the Cummins block to check flywheel and clutch assembly clearance. There is a 4.5 in. difference in length, so you will need floorboard modifications 4.5 in. back from the original location. Finding replacement parts and rebuild kits for Gertrag 5-speed transmissions is difficult and expensive. Change to the NV4500 transmission with the help of Advance Adapters Mopar NV4500 transmission bellhousing adapters.

FTI Performance offers torque converter dump valve kits for a variety of transmission applications, including the GM Powerglide. Typically used in drag racing, a properly designed, tuneable dump valve system lowers the oil level in the torque converter by bypassing charge oil back to the oil pan causing cavitation within the converter. This cavitation reduces the forward thrust generated by the converter against the flexplate—which helps to reduce engine thrust bearing wear, increase available stall speed, engine responsiveness and boost response/transition while staging against a transbrake in forced induction applications.
