Upper Windscreen Rubber & Xfer Case Fluid
 

A) What type of fluid goes in my transfer case? Regular tranny fluid? Ive done the filter and fluid on the transmission, but want to drain the transfer case to give it new blood as well. I know that it being a 2001 I dont have to worry about adaptive values. 2001 4.4

B) The thin strip of rubber on the roof/windscreen line is shot. I actually took the water hose and blew most of it off. Underneath is just metal. Im getting zero wind noise, but Im sure it will rust if I dont paint it etc. Is this replaceable or only coming with a new windscreen? Oddly, the glass is original and perfect with 179,800 miles.

Thanks for the info & help!

I can't really answer your questions exactly, but I CAN tell you I had the same problem with the strip above the windshield. Just so happens I had a cracked windshield as well, so I had the glass guy change the strip. What I can tell you is that this strip is completely redesigned from what was on the car.

You can order the rubber strip for about $20. Here's the link for ECS Tuning:

BMW E53 X5 N62 4.4L > Exterior > Window > ES#93002 Windshield Moulding - Upper - 51317182004

Yeah, but I think he wants to know if he can replace that strip without taking the glass out. I'd like to know as well. As far as I can tell, it is just held in with clips.

I've read that if its a BMW windshield that you can just swap it out. There's videos on YouTube of people changing them on different models, it's common for Bmws. I ordered one last week, and will be doing mine as well.

The transfer case uses special BMW transfer case fluid. Part # 83220397244

I put RedLine ATF in the TC at 100k miles. At 155k now with no issues, even towing 6k lb trailer in 110deg F TX heat.

Cool, thanks! It's actually a tiny bit cheaper at ECS ($20.96) than the dealer. ($21.80 at Tischer BMW)

Glad to help!

For a 2001 E53 he just needs Dextron III ATF. The NV125 transfer case doesnt need the same fluid that the x-Drive transfer case does. The NV125 was used until 2003 and after. Apparently 2003-2005 models needs to be visually checked for which case is in it, as there may be some crossover.

The xDrive transfer case uses the BMW Part # 83220397244 fluid which is most likely what our 2005s use.
