Jatco E39 528i M-Sport Transmission fill plug not found

Hey guys,

Ive been wanting to do my transmission flush and change the filter, I have everything ready but just cant find the fill plug anywhere. Searched the web with no luck of finding a transmission like mine. Any help would be much appreciated

Here are some images of my transmission, couldn't take any wider shots cause was up on jack stands with not too much clearance.

There are 2 bolts on the bottom, one with the Hex i know is the drain plug, not sure what the other one is for... Filter?

_{the one with the allan key hole is the fill plug .}

So the one one that looks like a bolt is the drain plug and the other one is the fill plug? So this one is filled from the bottom up?

Yes, you'll need a filler pump with a pipe and a soft ubend on the end. There's a tube that runs up into the box, and the top of it defines the fluid level (it runs back out down your arm when it's full). Level is determined hot and running in gear at a set speed, so you might want to take it to someone with a lift...

Don't bother buying a BMW filter, it's the same as a Nissan so any auto specialist will have them (and the gasket) in stock.

Alright thanks for the help, will open the allan key one and have a look.

Can someone give me a recommended Transmission Fluid for this transmission?

Ive been given these options:

- ATF5005

- DEX4

- Syntrans MV 9340-5

Are any of those good or is there a better one?

Thanks in advanced
