Transmission Overview OEM automatic transmissions are more closely matched to their use through valves and varying clutch capacity, with the intent to provide an inoffensive "softer" shift. This soft shift is achieved through a certain degree of "slippage", which can lead to overheating, a measurable loss of efficiency and a premature transmission failure. Vehicles of later model have carparts a torque converter that engages in high gear, and in some cases second and third gear, creating lower RPM''s suited to emission control. To create a transmission that is better suited to meet the needs of our customer, our company offers everything from completely rebuilt transmissions to various component kits. Our valve body and reprogramming kits offer more positive shifting, performance oriented automatic shift points and full manual control when desired.

The 9" converter comes in varying degrees of looseness carparts and tightness to maximize the applications. our company ‘s 5000-stall converter is intended for heavily modified engines with high rpm capabilities. Under no circumstances should you use a 9" converter with a late model "smog" motor that is incapable of making usable power past 4000 rpm. Make sure a transmission cooler is used as well. Each converter we manufacture shares many of the same features as our company’s famous 8" competition converters including furnace brazed fins, a specially matched stator, a heavy-duty sprag, needle bearing thrust washers, hardened races and complete leak testing and electronic balancing. Competition Converters Our 7" and 8" converters are recommended for big block combinations usually up to 600 cubic inch requiring stall speeds up to 8000 rpm. The our company 8" converters are ideally suited for the serious E.T. racer.

What happens in these situations carparts is that the converter''s torque multiplication capacity is being utilized to the fullest, rather than relying on pure engine power output. The matter of Stall Speed Vs Flash Point and related driving techniques depends entirely upon the application. This is one area where our company excels and can provide you with personalized technical assistance. Street Strip Converters Probably the biggest mistake a performance enthusiast can make is purchasing the most expensive converter around and the one with the highest stall speed. Too much stall speed can be detrimental. On the street, too high a stall speed will result in poor low-end response and a car that is difficult to drive. The ideal situation occurs when there is an abundance of low-end torque multiplication and the converter stall speed is suited to the power curve of the engine.
