Any of you ever tried Mobil Universal Sun synthetic in your ZF 6.speeds? It was recommended by a transmission shop and I have never heard of it.
Thanks

 

Why not go with Mercon SP ATF? It has been long-proven in these ZF 6HP26 transmissions, meets the required Shell specs, and remains very affordable....

"Universal" is a dangerous term in the ATF world....

 

No reason other than exploring other options. I have used it as well as lifeguard 6 without any issues

 

Great question! My research shows that Mobil 1 Synthetic LV ATF HP fluid "meets or exceeds" the requirements of JASO 1-A and Ford MERCON V. It is spec'd for 2000-2002 XK's with ZF6 transmissions. Both Mobil 1 Synthetic LC ATF HP and also Mobil ESSO ATF LT 71141 meet this spec, (as do Pentosin ATF1, Valvoline Maxlife ATF and MERCON V, among others).

2003-2006 XK ZF6 transmissions require an ATF that meets Shell M-1375.4 specs. Honestly, MERCON SP can't really be beat, and the price is right...

Hey Redline, good to see you. Agree Mercon SP. Thanks for the spec's on the other ATF's. Castrol Transmax (Dex/Merc) seems to be another choice in here.
