I don't think anyone mentioned talking to ZF, but I can tell you that ZF doesn't make their oil it's rebranded Shell M 1375.4 as another member mentioned.

Myself I've used Pentosin ATF +1 and it's the same.

Does any know what is the torx size of the 24xBolts on the plastic sump of the auto trans on E60 6HP19.

According to the link below it should be using T40;
https://5series.net/forums/diy-do-yo...-refill-88129/

According to BMW part number, there is no information;
Torx screw - 24 11 7 552 108 - M6X28,5

According to the bolts on my sump pan on the car, it is T27.

Reason for this question, when I already know that T27 is what I have on my vehicle - I am planning to replace the pan and oil on the my trans and 14 bolts seems to have its torx teeth #@#$#@ by previous INDY's, so I will need to replace these bolts. The new bolts which I will buy, I need to know the size of Torx bit so I can by that tool as my hollow Torx bit T27 broke while I was trying to un-screw the pan

Also, what tools was used to open the fill plug, I know it needs 8mm Hex socket, but mine won't fit since there is very less space and the thread above says to use L-shape tool, what is L-shape tool?

L-shape tool -- hex bit (long one) bent to a shape of "L"
Hollow Torx screw is called security torx. Why were you using the security torx bit? Get yourself a good set of torx and reverse torx bits set.

Thanks PCY, if you are saying to use "hex bit (long one) bent to a shape of "L" ", then how can one do torque on that bolt on the transmission to 25lb/ft??

No, of course you can't measure proper fastener torque with an L shaped wrench.

Buy a set of drivers like this to fit your torque wrench (1/4", 3/8" or 1/2").
3/8" Drive Star Bit Socket Set

If you do suspension work (higher torque values) you really should have at a minimum a 3/8" and 1/2" torque wrench, and ideally a 1/4" also for small fasteners and tight places.

Follow the tightening pattern on the pan bolts strictly in order as the pan is plastic and will not compress the gasket evenly if the pan distorts when being torqued.

I bought Land Rover's LRN13754, which as you can see by the part number, is SHELL M1375.4. After reading numerous treads, it was the cheapest Shell oil available (bmw wanted 40$/liter, land rover is 14$).
I decided to stick with OEM oil, as I had a w203 mercedes and changed the oil for non-oem (but better on paper than oem) spec and had erratic operation until i flushed everything out and put back one of the approved oils on Mercedes' list.

Thanks, I have a proper hex bit socket, but it is too long. In order to avoid using the L-shape key, I need the hex bit socket length to be 30-35mm at the max. Otherwise, only L-shape will will fit.

Guys, just in case the above post is confusing, I would like to know following;
1. What is the torx size on the bolts that hold the plastic transmission oil sump pan, T27 or T40 (why am I asking the question? -> read above post)
2. Is there a socket available that will fit the small area to undo the filler plug on the transmission? (So, I have only read about the L-shape tool but those do not let you torque it to specification and I can't find any 8mm socket that is in total length of 30-35mm as that is all the space there is near the transmission).

1. who cares, buy the whole set of torx bolts you'll need them. While at it go get some new bolts which are hex heads and some copper washers just like the oil drain plug. They will not break or strip on you.
2. I don't remember the size of the allen wrench but I think you'll need 2. A man can never have too many tools.

Go to Ace Hardware and take a bolt from pan with you, you'll match it up like I did. I posted it in the tranny DIY. But you'll still need the torx set eventually so keep it.

Calibrate your arm when you torque up the drain plug. Remember how hard you pulled, and do the same when you use the L-shaped wrench on the filler plug. Not ideal, but it works well enough.
