ATF-3+ transmission fluid equivalent?
Does anyone know if we can purchase a lower cost tranny fluid than this BMW ATF-3+ fluid they basically try and restrict us to?

Thanks so much. Do you know if there's a procedure for a person without any flushing equipment to get all the fluid out of the torque converter as well as whats drained by gravity?

There is no need to get everything out, i.e. torque converter and heat exchangers. It's completely okay if some is left in, and extra work involved will give negligible to no difference. |

Why do you think that there is water getting in there and from where is it getting in from? Small amounts of clean water wont do harm as it is boiled off during operation.
By undoing the valve body, I mean slightly undoing the bolts so that you can drop it few millimeters while it is still held up by the bolts. This will let it drain the top side via the gap made by loosening the bolts a little. Last edited by Raimo5; 12-14-2023 at 10:21 PM.. |

In that case, the transmission and everything that holds transmission fluid must come off the car so it can be drained properly. Other possibility is dynamic transmission flush, but I dont recommend it, as their "flush fluids" are cheap base stock and full of nasty detergents.
I really wouldn't bother and have faith in ZF's excellent engineering. Especially if there are no complaints with the transmission. They put these transmissions to some heavy offroad vehicles. |

Regulating O2 sensors are mounted in the front section of catalytic converter. These can be accessed from engine bay. Part #1 on this chart.
P0171 is bank one lean code. Has intake been checked to make sure there are no actual leaks? |

I would first approach it with electronic diagnosis system, because that does not require disassembly of anything and can rule out sensor and probe issues if you can interpret the data correctly. Usually, there will be disagreements between MAF, MAP, O2, adaptations if one or more of those are faulty. If all checks out, then I would start by inspecting intake parts. If memory serves correct, then N63 has completely separate intake tracts for both banks. That can give a good reference how parts should look and what noise they should make under operation. In your case, bank 2 is good. So if you listen to and visually check parts, make sure that everything on bank 1 intake run works as on bank 2. If you find discrepancies, audible air leaks, then that would help you pinpoint the issue. Again, 1000x easier with smoke machine. I can help you out with repair manuals if you need them. It would be the passenger side on left hand drive vehicles. If you stand in front of the car, looking at an engine, then cylinders would go as 1-4 (one being the closest) on your left hand and 5-8 on your right hand. EDIT: Lets move this conversation over to another thread that you have already opened. Last edited by Raimo5; 12-23-2023 at 11:02 PM.. |
