Thread: best way to swap trans fluid in a ZF?

If you don't want to drop the box the trick I heard was do either a few flushes or as stated disconnect a cooler line and keep feeding fluid in while it's running. If they are different colour fluids it is supposed to be easy to tell the difference.

Also what's this alternative to transmax z???

Costs an arm and a leg to replace that stuff at least once a year.

Hi Edd
I have Penrite ATF-Synthetic.

I had the disco flushed and a new filter fitted last year by an auto trans specialist.It worked very well as there was not even the slightest streak of dark fluid afterwoulds.To me it is like the cooling system,get it done once properly by a specialist. Pat

Andy... DONT USE THIS....

Correct Penrite for the ZF is Penrite BMV....

I spoke to a tech at Penrite at length about this.... BMV is the one you need to use, not Penrite Synth.

Hi Toombie
Will double check the lable,it does have Range Rover/Landrover along with a heap of european makes on it,but it could be the newies.
PS,this stuff INSNT Penrite SYNTH you see in Supercrapp etc. Penrite ATF-Synthetic.The local mechanic that long since left bought it for my Grader,we inherited it when he left.We were told not to use it in the grader as it isnt the correct spec and will void our warranty.
Im running it in my TD5 manual at the moment but after reading some of Rick130s posts I will revert to a MTF once I start doing more towing.It has fixed the baulking in my 243000km old box nicely

I think I posted this a week or so back, but it doesn't hurt to do a re-hash.
This is the official ZF TE-ML-11 approval list for their transmissions. http://www01apps.zf.com/kst464/ZF_In...doID=1&id=2371

Here is the TDS for Penrite BMV http://www.penriteoil.com.au/pis_pdfs/PI_ATF%20BMV.pdf
This doc is interesting http://www.penrite.com.au/tech_pdfs/74_ATF_BMV.pdf

and FWIW, Penrite SIN ATF also lists ZF TE-ML-14C (synthetic commercial vehicle ATF) as a spec it meets.
Commercial ZF (TE-ML-14) approval list here http://www01apps.zf.com/kst464/ZF_In...doID=1&id=2493
<edit> As Mike suggested, I'd check with Penrite before substituting SIN ATF for BMV. Just cause it lists the commercial spec doesn't automatically confer it meets/exceeds the 11b spec too, even though fluids like Transmax Z are dual rated.

Interesting, but do you think LR used Esso LT71141 in their automatics from the factory? Perhaps in D3s but I doubt in any D1/D2.

I use the BMV.

More than likely one of Texaco's Texamatic fluids that was on the approval list, seeing as they had such a strong tie in with Texaco UK at the time.
TE-ML-11A are mineral based Dexron II spec fluids anyway.
