Been having similar issues for a month or so with my F6 ZF 6 speed. It does the bang into 1st at take-off from lights, and also sometimes flares between gears. The latest annoying one is it "hunting" in revs at any constant speed from 70kph upwards... Like it's unable to lock into gear. So far, have changed the pan (with built in filter) and changed the fluid... Still no better... By the way, Mine has 90,000ks on it, and has been running 320...330rwkw's most of it's life. We have a fault code 701 which translates to "Trans control system circuit out of range/signals from trans control out of range". "Possible causes.. Faulty wiring/and/or connections" From what I'm led to believe, a proper ZF "scan-tool" is required to fully test the box? Next is a drive to Kewish Auto's in Dandenong (unless someone here has a better idea???)
