This Fluidmatic claims to meet ZF M-1375.4 Shell Specs. But you're saying this alone doesn't pass muster? link https://catalog.lubricants.total.com...UIDMATIC-MV-LV
What are the chances of just flushing out the transmission and starting over again? I recently took a trip that total'd a few thousand miles up to Canada from CA. The vehicle has 55k on it. Does the transmission stand a chance of being saved? |
1. I understand it was two different shops. I understnad the second was the "ZF certified" shop. Telling me that it was a self-promotional claim about being only one of 15 in the USA helps. Discount this 100% unless you can verify with ZF.
2. BMW doesn't pump out software updates for the transmission left and right. If your car has the 'proper' SW in it, and it is likely it has, there is no update. Anyone -including BMW- can press the 'reset adapttations' button. There are perhaps 100 posts here and on Bimmerfest of people that have reset adaptations an it has (1) worked and (2) not had a negative impact. Hence this 'one of 16 ZF certtified shops' advic3e to not reset adaptations seems like stunningly bad advice.
3. ZF recommends only ZF fluid. Period. BMW recommends only ZF fluid. The fact that ZF fluid meets 1575 and 'other fluid' means 1575 DOES NOT MEAN that ZF='other fluid'. Remember those Venn Diagrams? Classic example.
4. To be frank, I would not be concerned about your mixed fluids. If you are having ANY shifting issues, don't worry about fluid. The fix is probably a 2x drain and fill, which will get 75-80% out (math subject to correction). But again, why piss away $$$ if you are still chasing issues.
5. Why didn't you (they) do the mechatronics sleeve when they dropped the pan and changed the filter?!?
