young 01 Member 28 Member For: 14y 5m 11d Gender: Male Location: Vic Posted 04/10/10 09:27 PM Share Posted 04/10/10 09:27 PM Not sure if it is just my F6 or if it's a common issue and I just need to get over it but the downshift from 2nd to 1st is pretty severe and is causing concerns. Mainly happens when pulling up to a round-a-bout, almost coming to a stop and then accelerating (normal driving, not sinking the boot in). The gearbox hesitates then clunks/bangs into gear? I have taken it back to the dealer and they found that the rear seal had split and thought this may be the cause, smoothed out an upshift issue I had in higher gears but not this one. Do I need to keep pushing this with the dealer or are all others the same??? Cheers . Link to comment Share on other sites More sharing options...

I was linked to recently from a thread here. The ZF shunts his car when slowing to an almost stop then applying a bit of throttle again. I'll see if I can dig up the thread once I'm home as it's in my browsing history. Basically it's a known problem but still seems hard to get it fixed under warranty at some dealers.Hope you can get a new box!Oh I also have a similar thing in mine, when coming to a give way T junction as I leave home, if I dont completely stop the car will shift from 2nd to 1st as I'm pulling out into the corner. There's a fair delay in the shift and if you aren't used to it you'll apply more throttle, but then it hits 1st and the extra throttle makes you burn off like a madman. If you are just patient it isn't so bad except for the crappy delay.I think it's not being sporty enough on the change and holds 2nd for too long due to me not hammering around in D very often. I use semi auto 95% of the time so I can control the gears as I see fit. Edited 05/10/10 04:05 AM by -SteveR- Link to comment Share on other sites More sharing options...

Steve, it would be great if you could dig up the link for the Jag, sounds exactly like my problem, I think I will push the dealer harder for a change over. I like the idea of manually shifting although with this being my first Ford I am struggling to get use to the reverse shift pattern. Link to comment Share on other sites More sharing options...

Complained like fck but got nowhere at the time, and have just learnt to drive around it now I guess (don't even notice it).Have found when driving in full automatic to prevent the 2-1 lurch you need to almost stop and then roll forward a bit slowly so then the down-change is smooth and you're in the right gear to take off. Or otherwise you could just drive very sedately and it'll never use first gear (or use manual all the time obviously). Link to comment Share on other sites More sharing options...

Variant 2 is exactly the issue I'm having, problem is that if it's been going on that long and they still haven't found a solution I think I will have to learn to live with it although I will still push the dealer as it can be pretty severe. Thanks again for you help on this. Link to comment Share on other sites More sharing options...

Was something one of the BMW guys found out.From memory it was accelerate to 100 in 6th, then roll to a stop on each go. Do this 6 or so times, and it helped teach the box how to shift properly. Didn't solve it or make it fully go away, but did help.If you read the link from the BM driver that took a ZF guy out for a drive, he's basically been told its unfixable. Is the base software in the box that causes that, and is not something Ford can fix. Its essentially a built-in "feature" that can be fixed.I remember when I first got the car, variant 1 almost put the front of my car into a wall a couple of times, until I got used to it. Although I ended up getting a new auto from ZF, for other reasons, and that seemed to have made the problems less noticable. Its still there, but scarcely noticable.

spic Donating Members 148 Member For: 16y 7m 16d Gender: Male Posted 07/10/10 05:16 AM Share Posted 07/10/10 05:16 AM Just wanted to get on the list as I have exactly the same issue. Call me a skeptic but if it's an inbuilt fault with the software why aren't we seeing more members highlighting this issue?Would be nice if anyone is experiencing this issue pls drop a short confirmation on this thread, the more incidents we get may give us a bit more muscle. I have access to ZF staff thru work but didn't want to make contact until I could get a few more members on the list. Link to comment Share on other sites More sharing options...
