Penrite ATF FS

Has anybody had any problems using Penrite ATF BMV in the ZF 8 speed box?

Drover will have your answer bjm....from memory its not for use in the 8spds...is used in the 5spds and transfer case but Im sure all the 8spd owners are using BMV (?????...something like that) and Drover just came across a NULON alternative which was cheaper and in his opinion peformed better...he's usually on here early n then later in the day unless the weathers shyte...lol....could try a PM and he responds quickly...cheers

It should be BMV for 8 speed. I have changed mine to BMV with no issue. Had a leaking pan plug so have had another oil and pan change with 10k km and is running like a dream now. I don't see any shifting issues or anything

My error should have said BMV !

Just on a side note,
I notice alot of people seem to get issues after, changing their transmission oil and their transfer case oil.

Bear with me on this one, as it comes from a machine operator.
Back in the day when i was learning to drive an excavator, dozer etc. I was always thought, that when tramming them a long distance in one stint, that it was good for the final drive, oil pumps etc. to stop after 3-400mtrs rotate the machine and reverse for 3-400mtrs stop and repeat until you got too your destination. Reason being that this prevented the oil from finding a simple path through the system, which resulted in not all of the oil being circulated, which caused overheating and cool pockets of oil forming in low flow areas, by reversing then you reversed the oil flow and used 100% of the oil rather than maybe 70 or 80% if you didn't rotate.
My theory, which is all it is, is that because we drive our cars forward for 99% of its life, then in the transmission, and transfer case's low flow areas develop where all the shit and curd could potentially build up. So when we add new oil it may tend to disturb this and cause issues.
So might be an idea before you change the oil to reverse the car around the block a couple of times, before dropping the oil.

A couple of changes with BMV, no drama at all and the recent intermediate (emergency job) the tranny shop in Toowoomba filled it with Nulon full syn ATF done about 2K km including towing so far, smooth changes on cold or warm days, very pleased with it...

Hey Pete missed your call I was snoozing, not travelling well today, shoulders gone again......
