Fun with Lokar kickdown

I got the new (rebuilt a year ago and just sat on a shelf until this weekend) 727 in and made up some new fluid lines to the cooler. Now Im trying to get the lokar cable fine tunned, the cable was on the old tranny for about 2 months so Im pretty sure that all the streach is out of it. My 1-2 shift is nice and firm but my 2-3 shift is all weird. From a dead stop it will shift into 2nd fineand when it goes into 3rd it will "pulse" until I let off the gas just a little bit.
All of the slack is out of the cable and Ive tried adjusting it abunch of different ways, Im tired of dealing with it and thinking about going back to the 3 peice rod set up. So far it looks like I paied 64 bucks for a billit headache.
Has anyone else had problems with the lokar kickdown?
