cat007 Member 236 Member For: 6y 10m 3d Posted 12/05/21 07:51 AM Share Posted 12/05/21 07:51 AM Could be as much as 300ml difference in volume from cold vs hot.IIRC when I replaced my fluid, it was about 5.5L to fill it according to spec. Don't quote me on that. But 4.5L seems too little...

I have heard of a lot of transmissions failing because the fluid was dirty or it didn't have enough fluid in it. I have never heard of a transmission being over filled, well at least not a ZF because you can only get a certain amount in before it will drain out. I'm not here for forum kudos, I worked as a mechanic years ago and still do all my own work at a friends shop. We went through this all 3-4 times last year filling and refilling the ZF. We followed the ZF procedure on 2 different occasions and when I drove the car hard it went into limp mode. A transmission shop recommended filling when cold so I tried that and got a litre in or so. Had no dramas since x 2. You cant guarantee the conditions to be perfect on every transmission with the 'warm' theory. We live in Australia it is basically warm all the time. I have a trans fluid temp gauge on mine and it is usually at 25 degrees every morning when I start the car and only takes a few minutes to be over 30C.

Do it from cold or you will underfill it.

cat007 Member 236 Member For: 6y 10m 3d Posted 12/05/21 08:36 AM Share Posted 12/05/21 08:36 AM I think that's the point. Cold and the official recommendation is the same thing. Just means not 'operating temperature'. Link to comment https://www.fordxr6turbo.com/forum/topic/96247-transmission-fault-code/page/4/#findComment-1704726 Share on other sites More sharing options...
Puffwagon Gold Donating Members 16,348 Member For: 10y 5m 8d Gender: Not Telling Posted 12/05/21 08:40 AM Share Posted 12/05/21 08:40 AM I mean cold as in the first start for the day, not after running for a minute. Literally have someone in the car, raise the hoist, get them to start the car and put it into drive and start filling until it comes out. I spose if you live in nth qld then 30c might be your starting point. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96247-transmission-fault-code/page/4/#findComment-1704727 Share on other sites More sharing options...
