R ichard Member 75 Member For: 3y 9m 29d Posted 15/08/22 07:11 AM Share Posted 15/08/22 07:11 AM hay guys looking at getting a 2nd ZF out of a 2009 ge6T 90,xxxkm, guy has a built gearbox but is going in a different direction with his car, atm valve body and convertor are in the car with his built gearbox question is can I use the valve body and convertor from my gearbox or would they be stuffed from the coolant and trans oil mixing? car is going in on thursday for them to pull it apart but pretty sure its stuffed, when I we checked the oil line on the trans cooler it was pretty much all coolant 😒 im thinking it might be cheaper to buy the 2nd hand ZF ( 1200 nzd without the valve body and convertor or 1600 nzd with them ( would have to wait 2 weeks for him to remove them from car ) than for them to muck around pulling part mine and doing flushes etc is there anything else I should be aware of? sorry if they are dumb questions, any feedback is welcome Link to comment Share on other sites More sharing options...

Just wait for advice from the transmission shop that's pulling it out as to how much you have to replace. That $1200NZD was for a built box? seems too good to be true... so they're two different boxes, I assume? Another stock one is fine if you wish to get it. If you have big power goals just get the whole job from the built one Link to comment Share on other sites More sharing options...

Depending on your power goals, go with whichever full package and get rid of your own valvebody/tc/gearbox and replace it all, imho. (a few hundred extra for that peace of mind is worth it) Link to comment Share on other sites More sharing options...

It still doesn't mean it got into the box and stuffed it when it initially failed, while it was running. There will be water/coolant in the box now but that doesn't matter. What matters is if it got in there when it was running and mixed up a milkshake for you. You still haven't told us if you dropped the oil and if it is clean or milky. This will dictate whether you need a new box or not. So...drop the oil, see what it's like and take it from there. Far out man To save further replies, if your oil is farked then the TC as well as the entire box will need fixing, including the valve body. You may as well swap the lot unless you're going to get a rebuilt box with a rebuilt converter. #woosah Link to comment Share on other sites More sharing options...

Keep an eye on your temp gauge for a while, as the radiator may still decide to not work properly after it got filled with oil. Link to comment Share on other sites More sharing options...

I may have mentioned it but you can use clothes detergent to flush it, it works quite well. A fair bit of oil will still collect in the header tank over the next few drives, pretty normal as the block and radiator will have residue. Anyhow sounds like it's under control now so crack a beer and cheers to good luck Link to comment Share on other sites More sharing options...
