Let's make N63TU great again: transmission oil change tips
It came to my attention that:
1. X5M oil pan is direct fit to our 50i the reason it's much better is that it's made from Aluminum - which has several times better heat exchange properties compared to stock steel oil pan. Thermal Conductivity [BTU/(hr·ft⋅°F)] of Aluminum is 118, while Steel is 17. Huge difference. Part # for X5M aluminum oil pan is 24117855261 https://parts.bmwofsouthatlanta.com/...117855261.html 2. Some may argue, but I think transmission oil should be changed every 40-50k miles (almost same as spark plugs). Yes, I know BMW says it's lifetime - but we all know it's marketing green peace BS. Attached a photo of oil changed at 60k miles: the person who did it (photos not mine) put 1qt of oil more than he drained meaning that about 1qt of oil was "used" since car left factory and was converted to either gunk or else. Both color and smell was horrible. Moral of story: IMHO yes, BMW is right - transmission oil is lifetime - only "lifetime" means 3-4 years until free maintenance is up. Then it's going to be your headache. ZF - the manufacturer of our ZF8 transmission recommends to change oil every 40k miles by partial draining from the drain plug and refilling. However, if possible taking oil pan and changing it's corresponding filter - is a lot better. Filter comes with oil pan (and gaskets and new bolts) and you can't change it without taking oil pan off. The person used a ZF transmission oil, but there are couple other choices available including OEM BMW ATF 3+ Automatic Transmission Fluid. P.S. I haven't done this myself yet, as I'm only at 30k miles, but I will update it with pics and DIY when I'll do. If anyone wants to contribute - you are more than welcome. |

Anyone actually do this? Confused by the photos. The filter is supposed to be attached to the pan but in that one photo of the aluminum pan and bolts I don't see a filter…
Also every picture I've seen has a plastic pan and not steel for the tranny. I also Find this odd.
