On the other hand, the 4L60E might only cost $1,500. The rate of increase of the duty cycle controls the TCC apply rate. The OEM ECU then ramps the duty cycle up to approximately 50% to achieve regulated apply pressure in vehicles equipped with the Electronically Controlled Clutch Capacity (ECCC). It was mainly used for - and 1-ton SUVs or trucks, starting with the 1991 model year. However, it might not be very suitable for vehicles with a short wheelbase as the 4L60E is a bit long lengthwise. The switch contacts are normally open and close when fluid pressure causes them to. # The Lock-Up Feel (LUF) solenoid was probably put in high end Cadillacs for seamless shifting. The 4L60E is an electronic transmission that comes from the 700R4. You wont be able to place the bigger transmission in the space of the smaller one. A better programming option is disabling the EC3 continuous slip, while keeping the pulse-width modulated (PWM) TCC apply so that the converter clutch comes on in a ramped, controlled manner. Its vital to be informed about the many modification options available and how they affect performance and durability. It will fit 4L60E transmission years from 1996 - 2003. 4WD or 2WD application?
