Having problems with my 2009 F6-E:

  • Jolt or Clunk (intermittant but frequent) when slowing down or stopping and tranny changes to 1st
  • Jolt or clunk (intermittant but frequent) when accelerating from stand still or slow roll
  • High Pitched Whine, seems to be coming from the front of the vehicle, audible on lower speed <70k and acceleration only
  • Ticking on idle

Local ford dealership just changed 2 side and 1 centre diff bushes sighting that this was the cause for both of the above issues. Looks like it may have fixed the acceleration issue but not the slow down to 1st change.

They sighted Idler & tensioner pulleys for the Whine and the idle tick. These have been replaced to but both noises persist.

My last FG Falcon was the 5 speed and I never had anything like this changing to 1st. I assume this is not normal. Any ideas?

ok thanks! so far the downshift clunk seems better now the diff bushes are fixed as does the jolt/clunk on accelerartion. BUT I assume the jolt on acceleration isnt normal?

I have also occasionally found when driving like your grandma's mother the ZF likes to remain in 2nd when stopping (which is good - no lurch into first)

Then when I decide to be less *beep* and stand on it from that stopping position, the ZF drops back to first and causes a minor driveline jolt.

I have a nolathane diff bush which Jesus will hopefully replace soon, I can fart and the driveline clunks.

mine did it quite badly when I bought the car (approx 8000klm ago) only when the oil was hot though. I got the oil dropped and new filter, gasket etc and hasn't done it since. That was about 2500-3000klm ago now. If you have a steel pan I'd imagine around about $400-$500. If it's plastic probably a little more. That's an option, or just have to drive around it. Or like Bionic said, drive in manual mode. First gear is rubbish anyway in my opinion.
