Best of luck with that Mozz. Auto box seems fine now. Had to put nearly two litres in yesterday. I think the box should be viewed as a Sponge rather than a vessel. I am going to go through the process again next week and see if I can squeeze a few more drops into it. Strange thing was that I knew that a large amount of oil had poured out during the engine change but the level test said I didn't need to add any oil. I had followed the instructions i.e. drive it around to get it warm but not hot, check the level with the motor running, go through the gears, check it again, add oil until you get a small stream. Didn't need any extra oil. Did the same thing yesterday after doing 250 miles over the weekend and I needed to add nearly two litres. No leaks visible so I can only assume that the transmission is a sponge!
P.S. shifts are silky smooth now.
Don't know who told you that. Gearbox level should be checked with engine running after moving through gears and placed in park. Gearbox oil should be cold.
