A sliding sleeve valve and method for assembly is disclosed. The second carrier disposed on the first carrier is integrally formed with the first carrier. The calibrating device further includes thereon a second set of three projective points and a second set of three calibrating points for matching each of the projective points on the calibrating device with a corresponding one of the calibrating points by adjusting an angle and a position of the reflective lens on the carriage so as to achieve a calibrating function. The output shaft is continuously interconnected with at least one member of the planetary gearsets. The controller calculates an on-coming clutch pressure based on the on-coming torque value, and an off-going clutch pressure based on the off-going torque value. The correlator running a variable length pseudo noise code combines the code and the carrier which relates the incoming data signal to a correlation value for detecting the data signal.
