Re: ZF-8 fluid change - good for life?
Dry fill is for a new/rebuilt unit that hasn't had fluid in it yet. The trans fluid is supposed to be a lifetime fill but I don't really think that's a great idea for very long term dependability. It's a pain to change since there's no dipstick; it drains and fills more like a transfer case than a transmission.
