Leaving break-in oil in parts, especially non-filtered mechanical parts such as the transmission and rear differential was something I wanted to attend to sooner rather than later. Today, I drained the trans oil and replaced it with new stuff.
I'm very glad I dumped it. My eyeball (even though it's not scientifically calibrated) told me changing it out was a good idea....glad I did it. I'm not sending it off for an O/A and I'd bet it would've came back analytically fit for continued service based on the miles in service (10k) but now I know it's free of break-in debris floating around inside the trans and it has nice fresh red colored oil inside again.
I guess my point is for you guys that haven't serviced your manual tranny, go ahead and do it....it's easy, only takes 6 qts of fluid and about 30 min (max) of your time
I know that the ZF has ATF instead of gear oil but I am not sure if this is synthetic or if a sythetic version of it (Its Mercon isnt it?) is available.
I believe it does say Mercon however, I used a full-synthetic replacement (and it does shift a bit smoother now).
p.s. If you totally pull the check plug out and then pull the drain plug the oil comes out like Niagra Falls. I had a big concrete mixing pan under there and it was trying to bounce out of the pan it was coming so hard. Next time I'll leave the check plug in and just crack it some.
