This is in a large part what you will experience from a stock converter. This is the magic of the Stator, A stator MUST be designed properly or the fluid coupling of the converter will be poor and drive-ability and acceleration will suffer. At this point the Stator must redirect the fluid back into the impeller in an efficient manner or the converter will build excessive heat and acceleration will be poor. After the fluid is spun through the turbine it is redirected into the Stator. As the turbine catches the accelerated fluid the turbine is forced to spin turning the input shaft of the transmission. When in this cycle the impeller is picking up fluid and slinging it into the turbine. The VORTEX flow cycle is one of the most important and over looked segments of a converter. Once the stall speed is reached and the vehicle starts to move forward the converter is in what we refer to as the VORTEX flow condition of the converter cycle. As you push on the accelerator pedal and the vehicle starts to move this is considered the torque converter stall speed. The fluid coupling section is the operation that takes place when you accelerate from a stop when the engine is spinning and the vehicle wheels are not moving or just starting to move.(This part is where the Viskus clutch really shines). The fluid coupling portion and the lock-up portion. There are basically two areas of operation in a torque converter. The Viskus clutch drives real value comes in efficiency when driving at speeds between 5 and 50 MPH! The Viskus clutch provides for additional power transfer during these slower speeds providing a more positive fluid coupling. The Viskus clutch provides four to five times the torque capacity of a standard single disc converter and ensures there will be no slipping during hard accelerations or when pulling heavy loads. The Viskus clutch lock-up system is used to transfer torque from the engine to the transmission during high power applications when the converter is in lock-up. This pressure will cause the converter to balloon and the thrust bearings to get out of alignment causing converter failure. This is very important when needing a flat surface for the Lock-up clutches to couple with, this is also very important during times when there are high pressures created inside the converter due to extended load times when the converter is in a vortex flow. The Billet cover provides a multitude of benefits, having the thick steel cover provides a base that will not flex. The Radial Flank Square Tab is the back bone of the ATS TripleLok� and FiveStar� torque converter, all ATS multiple Disc converters are 100% square tab construction. We soon invented and patented the Square tab design that you can see and only get from ATS today. These pulsations are engine torsional loads that will destroy a converter and flex plate. We soon realized this to be a problem, after several thousand miles the outer plate would start to hammer into the billet cover due to the engine piston pulsations. In 1999 the first Diesel multiple disc converter was developed utilizing round tabs to connect the clutch plates to the cover. There are a few things that I would like to tell you about this torque converter. 4340 CNC cut Pump Drive Hub lock into Impeller Housing and Plasma welded for unsurpassed strength.

ATS engineered a unique two piece design that not only allows us to cut precision radial flank drive lugs into the cover but also utilizes a plasma weld ensuring an unmatched quality standard. The 30 square drive tabs that are precision CNC cut into the billet cover is only one of the many patented aspect of the Five Star� converter. The Five Star� has been awarded THREE patents from the United States patent office and has reputation to back it up! There is no other torque converter offered anywhere that can make this claim. The Five Star� Torque Converter rivals its little brother, the TripleLok�.
