Yes I did...But not with a AFM lifter but with a LS7/LS3 lifter...Either way if you are hearing tick tick tick more than likely its a lifter that didnt pump up which is causing the exhaust valve not to fully open and potentially grinding your cam lobes up too. Pull the valve covers off and see if you have any play in the rocker arms. Thats the best way to pinpoint the problem. Also check the oil for metal shavings. You wont see the pins that hold the roller in the lifter until the oil pan is pulled off. I had the pins stuck in the pick up tube. The hard shifting comes from the traction control being intiated. LMK what you find...I hope this helps..
