hi,
im sure the trans "gurus" will chime in.they helped me with the same problem.i used some of their advice and then came up with my own solution.
at the end of the small weight there is a hole that is slightly beveled to hold the spring in place.i tapped the hole and installed a screw that would extend almost the full length of the spring.be sure not to make it too long,as you need to leave room for travel for the weight.i used lock-tite to hold it in and then ground of the head of the screw almost flush with the weight.you need to grind it off for clearance.for reassurance,i put a dab of crazy glue on each end of the spring were it meets the weight and the housing .the crazy glue trick has been done by many im told.
now the installation of this screw could throw of the calibration of the weight slightly.i suggest grinding a little weight off each corner of the small weight to compensate.
this worked excellent for me.i just combined all the tricks from the advice i recieved from the many to come up with this and it worked excellent. good luck! nick,
