Thanks for input guys,Im getting some sonnax bits and converter for this one for now,With plenty of these about I can gradually build up a tough spare,and the best way to learn is to have a go, the worst that could happen is 1 less 4l60 in the shed I definitely wouldn't recommend anyone to cut corners like I have but I'm willing to get in the guts of it and figure them out, food for thought I recently fitted a 5sp auto zf box to an amg they handle over 1000nm stock and only around$4k,obviously pcm then is the problem but this computer has to go anyway because of next motors stupid cam, and for fun I could make a paddle shifter, I had the idea with this box but we all know how much they like being told what gear to be in lol
