To get all the fluid out on other vehicles you can remove the return line to the transmsission. You then drain, clean and change the filter, put the pan back up and fill. Start the car and as the fuid cirulates instead of going back into the tranny you put it in a pan. Pump a quart or two out then refill and repeat until the fluid changes color. Reattach the return line and there you go, all the fluid is changed.
Would that work on our cars?

I guess it should work but with fluid that costs a LOT of $$, might be a bit of waste. I can't imagine being able to clearly decipher the difference between new and used oil that easily. It all depends, how dirty the old oil is.

It's less wastefull then pulling the pan again and quicker. If you know how much fluid the tranny holds then count how many you put in when you filled the pan and then put the rest in.

There is no need to pull the pan a 2nd time. You just do it once when you want to change the filter. The proper method to top off fluid is to run the engine and let the fluid get to a certain temperature range and then to use the fill plug to top off. Measuring what came out is another way but not what ZF recommends in it's manual.

How does ZF recommend getting all the fluid out? Flushing machine? When I change the fluid I want to change it all. Even draining twice the old a new fluid mixes in between drains. It may not work on our cars just sharing information. I'll need to change my fluid soon. Don't believe in lifetime fluids. Who's lifetime anyway? Mine or the transmissions? Their not real clear on that one.

How has the transmission been acting since having this running for a couple of weeks? what are your thoughts on using Pentosin instead of ZF lifeguardfluid 6 which is recommended fluid from ZF?
if anyone else used Pentosin, I would like to know your thoughts as well! I have to change my out because there was a crack on my oil pan.
My dilemma is I cannot find ZF lifeguard 6, so looking for another alternative, But if you cannot get a 100% flush and you have to have 2 brands mix wouldnt this be bad?
Thanks in advance for you input.
