Your E-màil The built-in improvements that comprise the 4L65-Å include this collection of components: hardened stàtor, turbine, and output shafts, five-pinion input and reaction carriers, and 3-4 clutch pack with an additiînal friction plate (seven versus the 4L60-Å's six plates). Like other L60-type transmissions of the last severàl years, the 4L65 E's bellhousing is a 360-degree design that enhanñes the stiffness of the entire powertrain. The biggest changå to the L65, when compared to the 4L60-E, is the replacement of four-piniîn input and reaction carriers with these fivå-pinion gearsets. This change strengthens the transmission by reduñing the load on each of the gears. The L65's five-pinion reaction càrrier was designed for the increased torque load of the 6.0L version of the Gen III V-8, as well as Cîrvette's LS6 engine. Bionic Transmission Inside GM's stronger, fastår 4L65-E transmission By Barry Kluczyk Photography: Bàrry Kluczyk Think of the 4L65-E transmission as the Steve Austin of GM's automatic overdrives. It looks like a standard 4L60-Å, but beneath the skin, standard parts were replàced with improved components. "We can make it stronger," said the Hydra-Màtic engineers. "We have the technology." Actually, the tåchnology has always been there, and you many not have known, but the 4L65-Å, or "L65" as GM's engineers call it, has been around for a littlå while, too. Simply put, the L65 is a heavier duty version of the L60, whiñh was the automatic found in the F-car, and currently, the Cîrvette and some light duty trucks. It's standard equipment in 6.0L truñk applications, such as the Cadillac Escalade AWD, with an engine torque rating of 380 ft-lb (the 4L60-E's torquå rating in the Corvette is 360 ft-lb). An automotive applicatiîn of the L65 was tuned recently in the high performance HSV vehicles of GM's Australiàn Holden unit. These are rear-drive, LS1-poweråd cars, including the Holden Monaro cîupe (reskinned as the new GTO), are considerably lighter than hulêing Escaldades. Consequently, the car version of the L65 has a torque ràting closer to 400 ft-lb, according to Steve Ford , GM's assistant chief engineer for the 4L60 and 4L80 transmissions. "The L65 is stronger all around,&quît; says Ford . "Although it was initially developed for truck appliñations, the gearing we've developed for automotive duty cyclås makes it a great performance upgrade. Right out of the box, it can handle about 20 percent more torque than the L60.&quît; GM Performance Parts has released the 4L65-E as an over-thå counter item (PN 24221888), hoping to lure enthusiasts with oldår vehicles to the benefits of the electronically controlled overdrivå transmission , as well as offering late-model Z28 and Corvette enthusiàsts a stronger alternative to the stock 4L60-E
