Fuchs oil used in transmission service!

There is no issue with Fuchs, it does meet specs and is used in a lot of vehicles that run the same transmission.

I have been running it for a long time no issue, as has many of my friends.

If you want to spend the money to put yourself at ease that's fair enough but you don't have to.

Don't worry about it. I've done 100,000k with Redline ATF D6 which I put in myself when I changed the pan. The oil is listed as suitable for the ZF 6 speed. There are not many listed specifically suitable for the ZF boxes but Redline is and I presume Fuchs aswell.
It's a bit like being told that you have to use Mobil 1 in the engine. We all know that Penrite meets the specs and works very well, and many on here are happy to use it.

Interestingly I noticed yesterday that Penrite has an oil called ATF BMV that is now suitable for the ZF 6 speed. Their last version wasn't.

Long story short. I wouldn't worry about it. Fuchs, Penrite and Redline are all good oil companies with good product. You don't always have to pay for the name on the bottle.

Great service and I'm happy to have it go to them, only problem was the fluid they used in my 6speed ZF box, or the lack of communication around it. I was 100% sure they'd use the zf fluid because nowhere on their website mentions fuchs fluid and they sell a service kit containing proper zf fluid with no other fluid option. I was disappointed to find that they used fuchs when I didn't know I had the option! If I knew I would have just done it myself and saved $300 :( I queried it obviously as I was a little deflated, but they said it meets all specs and they use it all the time with no issue, mechanic uses it in his disco as well. This made me feel ok but I still have some paranoia surrounding a $7000 rebuilt if something goes wrong! They offered to dump it and refill with ZF and I'll pay the difference, but I dont know. It's probably nothing. What do you guys think? Oil is Fuchs ATF fully synthetic 4134.

I have used Fuch Oil in my D4 for some time now without any problems. My Auto guy says that the Fuch is better than the original.

have a read of this attachment.. especially the last page: ZF listed approved aftermarket alternative fluids

Don’t know what you’re reading on that PDF but there’s no listed equivalents for LG6.

And people... None - absolutely None of the alternatives like Fuchs or Redline etc are approved... there is an additive pack that is not available to ANY aftermarket blender.

It's not hard to do a full flush with LG6 as the incoming fluid. Have a look on the Pommy Disco3/4 website for a "how to do it", because I can't remember if it's on here (I think that there's a link, just search). You'll need about 11 litres for a full flush, and everything's cleaned out, including the torque convertor.

I did it - successfully - when I put a BMW steel sump, filter and pan gasket in October last year, in the back yard. It takes about 45 minutes.
If I can do it, nearly anyone can!!!

Change to LG6 - use the specified lubricant!!!

Otherwise you might Fuch it up.

Just bought a ford with ZF 6 speed, has done about 145000Km. ZF now states that the oil should be changed at this mileage, so I looked around for suitable fluids. Lots of "multi vehicle, do everything oils", ranging from $10/litre, up to ZF lifeguard6 @ $40/L. Read a very good article saying that any oil that is listed as multiple use, ie, mercon-V, and dexron111 and jatco-1, is not good for the ZF. The tranny requires a specific set of oil parameters, and other oils don't do as good a job. No, I don't work for ZF, and I am tight with my money, but these transmissions work really well, and I don't want to stuff it for the sake of a couple hundred dollars.
Regarding the Fuchs oil, it seems to be specific to one type of mercedes transmission, so should be OK until you change it.
cheers
