50I Oil pan upgrade DIY
I am in the process of upgrading my trans pan to the M model which is aluminum. There are several threads on DIY on this and thought I add some info. I have found out the most latest on our pans they are the plastic versions, which mine is an 16 built in may. I sourced the pan online for 286/325 shipped 2 day, and there were none in the mainland having to have it shipped from Germany for a 2 week turnaround, The fluid Lifeguard 6 I found on Ebay 7 qts for 145 and that included shipping which was a steal as most shipping was 30$. In talking with the local BMW Service Supervisor, he has seen the plastic ones cracking, I need to verify if anyone knows the exact torque settings for the 13 aluminum torx screws?

Make sure its aluminum as steel has diffrent torque setting *Aluminum 4nm + 45*angle turn (Replace aluminium screws; jointing torque and angle of rotation must be observed without fail. *Steel 10nm Torque Sheet Quote:

The irony is that ZF8 transmission is not that bad with temps (but still a good mod to have especially if you often do stop-n-go traffic in summer heat or tend to drive aggressively, tow often etc.), plus we 50i guys have extra oil cooler for it. I'm more concern about TC (transfer case) that if anything will fail (specifically due to heat) long before ZF8 transmission will. Just my opinion. It's same TC known for barely adequate oil supply for it's clutch and internals (due to poor engineering) - the result is that it starts to slip and then you get a shudder during acceleration etc. Timely TC oil change helps alleviate issues.

I love the DIY ya 50i guys are putting together. Let's keep it going. I'm gonna change my oil this weekend and add a DIY since I couldn't find one for the 50i on this forum. Found a couple through google and YouTube but we should at least have one in our thread. We need a TC oil change and a Rear Diff oil change!! Who's up?! Haha

Isn't the thread just "50i oil pan upgrade - DIY"? Nothing mentioning it's not metal. Just that an upgrade is available. Or is it different now?

Anyone know if the plastic transmission pan is reusable or do you have to replace the whole thing after a drain and fill. Was planning on doing it twice to clean out more of the old fluid. The pics online look like the drain bolt is plastic.

The transmission fluid filter is built into the pan so you should replace it when you change the fluid.

Hence the topic of this thread about upgrading the plastic pan to the metal one from the M.
