Evening all,
Picked up a 53-plate 4.4 V8 yesterday and originally thought the ZF box was going in to the 'cooling strategy' mode, and probably had a clogged oil cooler, etc, because it was holding gears for ages before changing. However, I've now realised that's not the problem...
If you start the car, the dash and lights near the gear selector correctly show P. Move the selector in to reverse, and they correctly show R, etc. If you move it in to drive, or sport mode, the gear selector lights always show the correct position, and the dash initially shows D as well. After anywhere between 2 seconds to 45 seconds later, the D on the dash will disappear, and the gearbox then refuses to change gear. If you slightly touch the gear selector (and I do mean slight!), the D reappears, and the car then changes gear. If you drive along with one hand held pushing the gear selector very slightly forward towards neutral, the D always stays lit and the car drives perfectly for miles and miles (but you do end up with a tired arm!).
Changes are nice and smooth, and basically the gearbox itself seems great.
I had a quick search around on the forum and couldn't find any threads relating to a problem like this, only people who couldn't get it in to drive at all. Presumably it's an issue with the linkage or the selector on the gearbox, but given that only the slightest of touches is required to make it work perfectly, I'm hoping it can't be anything too major!
Any thoughts..?
Thanks!
