I am new to this forum, so I do not know what others have suggested. On the transmission servo there is a small adjusting screw with a jam nut that when adjusted makes the hst more or less agressive. I need a picture to accurately point which one it is. Once you know what one, the further in or clockwise, the more agressive, or out and counterclockwise is less agressive. The servo is the rectangular black thing on the trans that has an arm attatched to it that moves with the throttle pedal to give you motion. Once you find it, there is a small screw with a slot in the end and a jam nut on the screw at the opposite end of the arm from the linkage. Once you find it, its really easy. From there, adjust it like I said before. It will take a bit of fine tuning, but it makes a night and day difference. If you need more in depth info let me know, maybee a phone call is in order?
