The recommended servo travel is 1/16”-1/8”. What should the servo travel be on a corvette? I did have to pull my trans crossmember down on one side and lower the transmission to get it to come all the way out. I called my tuner and he recommended this servo upgrade. The transmission (4l60E) felt lazy or slower shifts with the extra power. What kind of transmission does a Silverado 4L60E have? The first drive was great! It shifts short and crisp. How does a 4L60E servo work on a corvette? This helps prevent the transmission from slipping under heavy load, such as racing or towing, and is highly recommended for any high performance application. Why Put A Corvette Servo In A 4l60e? The corvette servo will give your 4l60e 50% more apply pressure, meaning it will allow for a much firmer shift. What does installing a Corvette servo do?
There are a myriad of ways to do this.Īre there clutches in an automatic transmission?īoth manual and automatic transmission cars have clutches that engage the transmission to channel the engine’s power and move the vehicle’s wheels, or disengage it to stop the wheels even when the engine is still running. The transmission turns the output shaft, which in turn spins the axles, which in turn make the wheels go. This type of transmission also uses a servo piston to activate and deactivate the bands. It tightens to engage the gears, and loosens to release them. For HD or HP uses, upgrading the servo gives the band the necessary clamping power to keep from slipping under heavy loads. The function of a servo in an automatic transmission is to apply the band or bands. What is the purpose of a transmission servo? This allows the shift to happen quicker which will reduce slip inside the transmission. The corvette servo will help improve the firmness of the shifts, especially the 2-3.
Is A Corvette Servo Worth It? Yes, installation of a corvette servo in your stock 4l60e is definitely a worthwhile upgrade for the cost. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4. If the transmission has a large 18-pin electronic connector above the passenger side pan rail, it’s a 4L60E, as seen here. You can’t tell the difference between a 700R4 and a 4L60E by the oil pan as they are nearly the same. What is the difference between 700R4 and 4L60? We offer a lock up kit under Part # 23-700R which can be used with carbureted engines or applications outside of the GM engine family. Although the 700R4 is not an “electronically” controlled transmission, this feature was controlled by a PCM.
