Cast Aluminum Stator Wheels for Torque Converters {3101, 3129} Cast Aluminum Stator Wheels for and repair are caused by failure to observe basic safety rules or precautions. If in doubt, go back to stock and see if it still does it. The classic torque converter design dictates that the stator be prevented from rotating under any condition, hence the term "stator". Its role is to reverse the movement of the hydraulic fluid from the turbine, prior to hitting the pump again. Poor Acceleration at Low Speed If the stator is freewheeling at all times, the car tends to have poor acceleration from a standstill. The oil that eventually finds it way into the cavity containing the impeller, stator, and turbine gets into the "guts" of the converter via passages in the centre shaft. When the stator shaft pushes out or twists in the pump body bore, the feed holes no longer match up and pressure goes to sump instead of to where it supposed to go. There's also the fluid itself, and often a lock-up clutch. Once the vehicle is up to speed, it feels fairly normal again. These may arise if it has damaged the needle bearings, seals, clutches or solenoid. Our race series converter should be used in Racing/Pulling applications that require a higher "Stall" R. OK Joe, the converter has a substrate biscuit inside the outer shell. My torque converter will no longer lock up, and the trans shop says the problem is with the torque converter itself. As fluid exits the turbine it is turning the opposite direction of the impeller. Annual losses attributed to waste ($). Resulting symptoms are overheat, converter issues, slipping or no movement. Inside the torque converter are rotating items, two of which are called a stator and turbine. I use Art Carr's valve although Mike Kutrz's is the same. In terms of rotating weight, that is significant, particularly among classes with lower horsepower engines. Specs: 12 Diameter Fixed pitch stator 30-spline input 3-lug mount Note: Certain models offered a choice between fixed or variable stator torque converters, you can easilly distinguish between the two by counting the wiring nodes on the transmission housing, one wire. Stator--- the stator can be described as the "brain" of the torque converter, although the stator is by no means the sole determiner of converter function and characteristics. Stator torque at incipient cavitation is a function of those variables that determine the boundary value problem of the toroidal flow, primarily the size and shape of the torque converter, blade geometries, and the charge pressure, , and back pressure, , superimposed upon the unit. I also installed a new SFI flex plate. on the asphalt,,,, block all four wheelspush the gas to the floor for just 2 secondsdown one, two lift off gas pedal quickly. Due to this it rotates and fluid present inside it is thrown out and reaches the turbine. 1999 - 2003 7. Torque converters are comprised of five main components: the impeller, the turbine, the stator, a clutch, and the fluid. Engine blocks are also covered if mechanical failure was caused by the above-listed parts. 5:1 ratio over actual engine torque at stall speed. Most torque converters multiply torque in a 2. Numerical Study of Performance of a Torque Converter Employing a Power-Law Fluid Shoab A. The stator, therefore, increases the efficiency of the torque converter.

It is what makes a torque converter a torque multiplier, and not strictly a fluid coupler. If a torque converter has been allowed to degrade to an extreme, there is a strong chance your vehicle will lose drive altogether. running rich. When the vehicle speed increases from slow to high, the need for mechanical advantages, decreases and the gear ratio of the torque converter gradually changes to that of a fluid coupling. The stator is a finned device that lives in the center of the torque converter, and its design directly affects the efficiency and stall speeds. sprag clutch for the stator in the converter. Torque converters combined with gas engines, even in high-performance applications. The Stator provides Torque Multiplication When the engine is running and the car is stopped, the stator will lock on the One Way Clutch The one way clutch is splined to the transmission oil pump cover or stator shaft that does not rotate This provides maximum torque multiplication At “Coupling Speed” the stator will spin freely on the overrunning (one way) clutch At coupling speed, about 10% of engine RPM is lost to ATF fluid slippage. Stall is the speed at which the converter will hold the engine speed and not allow further gain (i. In terms of rotating weight, that is significant, particularly among classes with lower horsepower engines. Re: Tranny/Torque converter noise Oct 28 2015, 2:38am esox07 wrote: I suppose you could pull the pan and see if you can see any obvious problems, but you are probably going to have to have a shop take a look at it. Technician B says that the pump (impeller) is the driving member and the turbine is the driven member. These converters fit Allison 2001-2015 Duramax LB7 - LML. This internal converter pressure, in the original 42 through 47RE convert- ers (figure 1), could be compromised with a leak between the converter hub and stator support assembly, allow- ing oil to be used/recycled through the pump gears. All are contained within the housing of the torque converter, which connects to the engine's flexplate (sometimes called the flywheel). The torque converter incorporates one major change from the fluid coupling: a third element (the stator) is designed into the unit. If the torque converter has been removed: 1. They refer to this application of clutches as "lock-up. Stator --- the stator can be described as the "brain" of the torque converter, although the stator is by no means the sole determiner of converter function and characteristics. The importance of stall speed is that an engine must be able reach an rpm where enough torque is available to accelerate the vehicle, but not running so fast that there is poor fuel economy and excessive noise STALL SPEED STALL SPEED Stall Factors The actual stall speed of a torque converter is determined by several factors: The amount of engine torque, The diameter of the converter, The angle of the impeller vanes, The angle of the stator vanes. This dramatically increases the efficiency of the torque converter. As the transmission fluid reverse direction and returns to the impeller to keep the cycle going, torque is created. I took the car '90 Mustang built 306, (450 HP at the wheels on a dyno) for a test drive and everything went great. All are contained within the housing of the torque converter, which connects to the engine's flexplate (sometimes called the flywheel). By making changes to each of these parts, a torque converter manufacturer can dial-in where the converter will begin to stall the engine. So I need a new one. Learn more about converters at risk for stator failure in “Defending the Duramax. Upon switching to the scan tool data list, the TCC Duty Cycle is at maximum but TCC Slip is high and there is no rpm drop when TCC is commanded on. This can cause several symptoms like slipping, overheating and rough acceleration. This torque-improving device was the first torque converter in use and, since it incorporated the stator (reaction member) to multiply torque, it formed the basic design for all modern torque converters.

It will stall the engine instead of just sitting on the torque converter. The housing of the torque converter is bolted to the flywheel of the engine, so it turns at whatever speed the engine is running at. Stall speed is determined by several factors, including the distance between the impeller and the turbine and the design of the stator. Torque converters, have two inherent, weak spots the lock up clutches, we all know, and the stator, overrun clutch, or sprag, or one way clutch, no matter what you call it it is the leading cause of torque converter, failure. A lot of bad things can happen to your car when the torque converter starts failing. The torque converter also serves as the engine flywheel to smooth out. The housing of a torque converter, which connects to the flywheel, contains three parts: the pump, turbine, and stator. A stator sandwiched between the impeller (input side) and the turbine (output side). OK Joe, the converter has a substrate biscuit inside the outer shell. Whether hauling a heavy load or running a lot of torque, automatic diesel trucks rely on the performance of their torque converters to translate engine power into drive power. The housing bolts to the engine flexplate and provides an enclosed area for these parts to perform their. This results in high stall speeds. This heavy load is placed onto the pump's stator tube. running rich. Torque converters provide a better launch in Continuously Variable Transmission (CVT) vehicles which solves a major problem of CVT vehicles. The angle δ is the angle between the stator and rotor fields, commonly called the torque angle. Buy a 2004 Dodge Ram 2500 Auto Trans Torque Converter at discount prices. When the vehicle speed increases from slow to high, the need for mechanical advantages, decreases and the gear ratio of the torque converter gradually changes to that of a fluid coupling. The stator's job is to redirect the transmission fluid from the turbine back to the pump, which causes torque multiplication. Many times, people think there is something wrong with their transmission when the problem lies with their torque converter. Invented in 1905 in Stettin, Ger-many, by Dr. The stator, which changes fluid flow between the turbine and pump, is what makes a torque converter a torque converter (multiplier) and not strictly a fluid coupler. Engine blocks are also covered if mechanical failure was caused by the above-listed parts. Remove the stator, and a torque converter will retain none of its torque multiplying capabilities. The best torque converters in the transmission industry to for GM, Allison, Chevy Diesel Trucks.
