Try this. Set the T.V cable correctly. The TV cable should be hooked to the carb on the lower half of the throttle linkage. In this way the cable is pulled forward under acceleration. This hook up knob on the linkage (the plate on the shaft of the butterflies) should be at the 4 o’clock position at idle and 8 o’clock at full throttle. The T.V. cable should be fully extended just prior to full throttle. The knob hook-up should be 1.125 inches outbound from the axis of the butterfly shaft at the 4:00 o’clock position when closed..

This part is absolutely crucial to the proper working of the 700 and I believe the misadjustment of this cable is the single most often reason for failure of the 700 tranny. I can not stress this step enough. If the cable is not set correctly, the shifts will be sluggish and early in rpm. This will cause the tranny to self destruct in a single outing.
