ATF Change - How many Qts?
I almost dread bring up another ATF thread but have a question. I have read probably every thread on this but am still confused on how many qts/liters are being changed. I'm back to thinking I'm going to have the pan dropped and fluid replaced. At first I thought this would be 6qts. But in the DYI it was around 4.5 I think. In other treads I see a range of 3-9 but sometimes I'm not sure exactly what procedure was used.
So if my mechanic drops the pan, can he get 8-9? 6?. I am ordering the fluid via mail so I have to pin it down. p2 |

I believe the total capacity is about 9 liters (for the 335i it is 9.5 liters) but not sure about the 325i. But you won't get all of the fluid out because some will be in the torque converter or other places.. so you'll get at most probably 6. Just order more if they're not that expensive, because if you realize you don't have enough last minute, you're pretty screwed.
Sorry this is probably not very helpful.. hopefully someone who has done the 325i AT fluid before can provide better insight. |

If you drop the pan you will definitely get more out.. I totally recommend getting 7 qts.

Thanks for the replies everyone. Here is how it went down. 58K on the car. I ordered the CTSC.com kit for the 6hp19 ZF trans. It had the pan and 6L of Lifeguard 6. Klaus assured me that 6 qts were enough. He was correct. I also ordered a sealing sleeve because of the high failure rate. Today may mechanic drained the ATF, dropped the pan, replaced the sleeve, installed the new pan and pumped new ATF back in. He ended up using 6L even with the little spill waste of checking the level. I checked out the old pan and there were no shavings with just a little buildup on the magnets. I'm back to butter smooth shifting. I think I will just do a drain and fill in about 30-40K and leave the pan for the life of the car. $275 parts, $175 labor, total $450.
As a side note: while the panels were off, he checked out a slight exhaust vibration thats been bugging me for 2 years. Adjusted a bracket and poof, gone. Nice. |

BUT!! The kit you ordered is for the ZF transmission, and in your profile you say you drive 325i. I believe the 325i uses the transmission built by GM, and only 330i/335i uses the ZF transmission! |

I would totally trust Klaus- he is a former ZF trans engineer. A few questions though- 1. How was your trans shifting before the fluid change (just asking if it was a placebo effect or a real change?, 2. How was the mechantronic sleeve condition? Was there any evidence of deterioration? and 3. Do you really have ZF trans? or GM trans? It is imprinted on the pan. My 330i has ZF imprinted.

Sleeve condition was good when he took it out. I saw no indication of deterioration and neither did my mechanic. But there was some discoloration of what I think were the seal rings on it. Yes it's a ZF. I checked multiple sources, looked at the sticker on the pan before I ordered, Gave Klaus the last 7 of my Vin, it said ZF on the old pan, Stickers for the AFT was for the ZF fluid, parts fit etc. p2 |
