Trans/Driveline Fluids Service

[Lexicon740iL]

I have decided to do a trans fluid service on my new E53. Mostly as Preventative maint. /service being the new owner.
I usually like to swap out the fluids so I know when the last service date is.
Also It does have a sight whiplash effect when shifting into second from a rolling start on cold mornings and It's becoming annoying.

I know the subject has been covered many times but I just wanted to start a thread to document my adventure and have you guys look over my list of supplies ect.

Transmission Filter - Transmission filter kit Made by ZF OEM Part # 24 11 7 543 550
Transmission Pan Gasket - Transmission Pan gasket Part #24 11 7 543 484
Trans Fluid Type - ZF Lifeguard 6 ?
Qty Needed - ?
Transfer case Fluid Type - Transfer case fluid. Made By BMW. Part# 83 22 0 397 244
Qty Needed - ?
Transfer Case gasket needed?



Bav auto has the trans service kit with the filter,gasket and o ring for 80.00
I'm guessing I can get the separate parts number for a bit cheaper from Tischer or my local dealership with CCA Discount but I noticed Bav auto has the ZF Lifeguard 6 Fluid also so I might just grab it all from them.

So First Question

The ZF Lifeguard 6 is the correct OE fluid I have in my 06 4.4i With the 6 Speed Auto right?
This is what I should be using correct? is that the general consensus?
Next
How much will I need?

The Bav. Auto says 6Qts for my Trans.

Is this the correct amount assuming I will be only dropping the pan, cleaning off the magnets, swapping the filter and gasket and buttoning it back up and topping it off?
I won't be flushing out the torque converter, lines ect.

While I'm down there I figured swapping the Transfer Case fluid would be a good idea too.

How much does it take my buddy who is a Euro indy said 350ML or something slightly more. Is this correct?

I'm assuming I can order a qrt. of the OEM lifetime transfer case fluid from Bav. auto also P/N 83220397244

Will I need a gasket for the Transfer case fluid swap? P/N? R&R post?

TIA Guys.

I did all my fluids in August before driving cross country. Wasn't difficult at all with the minor exception of needing to remove the reinforcement plate to access the front diff.

As far at the tranny, I got my supplies and read all the instructions here:
California Transmission Supply

Hmm. It appears the instructions are gone now. I may have them saved somewhere.

No, they are still there. Buried a bit
About Oil

I don't recall where I got the transfer case fluid from right off. It was the most expensive per litre of any of the fluid.

Get the x-drive fluid straight from the dealer. It is not expensive, but is a special sauce formula that you cannot buy in a store. I bought the service kit from BMW as well. Came with two new plugs that had magnets on them. You also need to reset adaptations on the X-drive. Some do it, some don't but it is recommended. No gasket needed. If I remember correctly, you need just the one bottle. It takes slightly less than the bottle.

Get new reinforcement plate bolts, they are one time use. Torque to yield.

Get the oil from Thectsc as Giznaz recommended. You will need 6 for sure with an oil pan drop. ZF lifeguard 6 is correct.

Thanks for the input guys.

Looks like I'll go with this kit.
Oil change kit for 6HP26x

REALOEM says I have the GA6HP26Z So I believe this is the correct kit.

There was another one that had a plastic pan that integrated the filter into the pan permanently I don't think that's what I'm looking for.

And the Transfer case fluid From Tischer

This should cover it with the exception of the transfer case bolts Slick Mentioned

I am not sure you need the new drain and fill bolts. You can easily re-use yours. But you might want to use new washers. When I got the service kit, it came with the fluid, new bolts and washers. I am almost sure ECS tunning had a package deal for all this for our Xdrive.

Yes, you have the metal pan, the plastic pan with the filter is for the 5 speed cars.
