#20 / 77968. 700R4 full throttle 3-4 up-shift sleeve.
700R4 full throttle 3-4 up-shift sleeve. Now you can have a full throttle 3-4 shift. At 80 MPH it takes 90% throttle to make a 4-3 downshift. Can be installed without removing the valve body. The Up-shift Sleeve also eliminates part throttle 4-3 downshift for less gear searching. This is an extra option on the 700 Raptor. Not recommended for motors over 250 horse power.
