Thanks for the info, WPoll! The fill port is on the back of the N62 pan. I'm not sure where the center point of the X5 is relative to that, but it seems to me that OldSkewel's technique would work if the difference in height between the front and rear jacks is significant. Works for him!

Your observation about the temperature of the fluid in the bottle made me think that I could leave it in the fridge overnight to make it even cooler!

BTW, did you see the edit I did in the last post in the other thread you helped me with? I discovered based on the PDFs you sent that the N62 is type A, which ZF says uses a different procedure for shifting gears (I think!).

I got my NT520 Pro and have started using it.

For transmission fluid temperature I'm using the path, from the top menu after scanning the VIN in the BMW section:

2. Control Units
1. Drive
10. EGS 6HP transmission control
5. Live data
1. Performance variables, gearbox: (checkbox) Oil temperature, gearbox [ I also checked Oil temperature, engine & Battery voltage ]
View Data [F3]

Does that sound right? Might be a little different from your menus, Andrew, or is there a different path to get Transmission oil, temperature, like you have?

I didn't update the unit yet.

There's also a 11. EGS 6HPTU transmission control menu choice, just below 10. EGS 6HP transmission control in the third step. Anybody know which is correct for an 04 N62? They seem to have the same choices available, at least for the live monitoring.

Numerous modules are duplicates I never know which Is the best one but I think they are basically the same with some minor changes depending on what is available.

Thanks! Let me know if you see a good summary of the BMW functions for the Foxwell.

I'm going to have some questions about reprogramming the transmission module after I finish changing the ATF. My mechanic friend says it's a good idea. Also, I think there may have been an update since the last time it was at the dealer, which was probably in 2007! I'll start a new thread for those questions.

Yeah, but don't do it. Not unless you've changed the mechatronic or some other major component. An oil flush (change) is NOT cause for a transmission adaptations reset - and doing so could possibly cause more harm than good.

Is that the same thing as updating the transmission software?

This info, for a 745i with the EGS 6HP, has Reset/relearn values as menu item 7. It's on a NT510.

Nope - not the same. A Reset/Relearn is an adaptation reset - to be avoided unless you have replaced major components in the transmission.

A software update requires a copy of the new firmware for the transmission controller (EGS) and a tool (laptop and software etc.) for programming the transmission controller. Note that I said transmission controller and not the transmission itself. Transmissions aren't programmed but controllers are.

The hand-held scanners will not update software/firmware in the car (in general).

No. That's updating the firmware on the TCU. Need a computer for that and I don't know which software
