Yeah the auto junk so sluggish,shifts so slow it drove me nuts was gona sell it and get a manual but have never seen one fully loaded,so just did mine,goes 100 times better pulls harder,heaps better on fuel,It was also the first thing i did as for me makes it way more fun to drive,and as for it costing 5-6g thats only if you like getting bent over,I got mine done with 33 box out of a stagea,new clutch,new centre console,pedals,ect. and its cost me $3500 best $$ i ever spent!!!!!
