adjusting lokar kickdown

Hi,

I put a thread up about 2 monthes ago about my transmission braking in 2nd gear. Called Cope transmissions and he told me to check the adjustment of the lokar kickdown cable. He said he's never liked them. This is the first thing i will check (finally getting around to it). The first thing that i noticed when looking at it is there is a little bit of slack on the cable when the car is sitting turned off, with no pressure on the throttle. Is this supposed to be tight? I wouldn't think there should be any pressure on it, but the slack may be a sign of misadjustment.

His second suggestion for the tranny was to check the screen, something may be in it.

Thanks
