Weird Zf Behaviour

[Big Dazza]

I have noticed that my ZF box behaves weirdly when coming to an almost stop then taking off (ie at a give way sign, speed hump etc.). It seems like it momentarily drops down from second to first then quickly back up to second, making for not very smooth take offs. It seems to happen mostly before the transmission warms up in normal driving mode, but sometimes when warm.

Is this a normal trait? I find it quite annoying. Possibly something to do with adaptive mode, and the car mostly getting driven like a pussy due to daily commuting (stays in second when almost coming to a stop). If so would disconnecting the battery reset the default settings?

Not really worried as the car is still under factory warranty, however I would imagine that it would be complete waste of time getting a Ford dealership to give me meaningfull feedback on this issue.

Feedack appreciated...

Cheers.

pulling the battery for 10mins will reset the adaptive learning.

Try running it in sports mode and see if it does it as well. I have noticed my gearbox also does it, but generally stays in 1st, but I drive it hard most of the time.

Mine does the same

yep mines the same. its done it since new so I never worried about it.

feels like it slips for a second before grabing the gear.

On the CAPA tune...the reaction/delay time of the ZF can be changed for when you nail it.

Apparantly it was Fords little safe guard for breaking things in the ZF

Wog changed mine in my t ute to no delay and the response for changing was better.

I'd probably say its showing signs that it needs the oil flushed.

My ZF has been flaring when its cold only recently.

Car has just clicked over 90,000ks

these zf's seem to have a few troubles here and there are they generally a solid box ?

just noticed a few threads of complaints

and a few of rebuilds

My car is getting a new ZF auto in the next week or so, this being one of the complaints I have with it. When it happens to me, its accompanied by a thud and a small shunt forward, as its pushing against the brakes. Most of the time you can hear a metallic noise with it.

This is one of a couple of complaints I have with the thing, harsh shifting being the common theme.

Problem surfaced when I started getting used to the car when I first got it at about 13,000km. Complained at the 15,000km service. Seen the ZF man twice and Ford area manager, and now finally they have agreed to a new box. Car has just touched 29,000km.

If you take it to Ford, push hard and keep arguing until you get a decent response. It may be as simple as the ZF bloke coming out and adjusting line pressures or something... But something Ford can't do. As you can see by the amount of time it took me to get somewhere, it's a painful exercise.

This sounds like a different thing to what my ZF is doing.

I came across this "shunting" type problem being discussed on another aussie Ford forum, with a link to a UK based BMW forum, where there seem to be quite a lot of complaints re: this issue. I think the trans slams down into first when coming to a stop.

If I find the link I will post it.
