Yes the issue is there from first to second from a stop if I goose it, but at half throttle to quarter throttle (when rpm's stay between 3-4000 rpm) the tranny shifts fine...

And no it doesn't slip w/o downshifting....at quarter throttle and sometimes even half throttle there is no slipping either.. but foot to the floor or almost foot to the floor, she slips everytime...
