MOines in. Not a bad job, just watch out when you drop the valve body cause the springs drop out their galleries, 3 off them come out and only one gets put back in after you blank the middle 2 off with the 50mm welsh plugs. O and you'll need 5lt's TQ dextron III comes in 4lt so buy that and 1lt extra. If it wasn't for the springs dropping out and having to sort them out which goes where it was about an hour to an hour and a half job.
Makes a huge difference. Much easier and cheaper than a manual conversion and I'm well impressed with the results for under 400 bucks.
Pay the extra and get the service kit. I removed the sump without damaging the seal but you'll do yoursellf a favour changing the filter.
Bang for buck it's worth it.
