Reverse Gear Engagement: Is this a fault?

I can't believe this has anything to do with my driving impatience, but is more a fault of the 6-Speed ZF gearbox, and perhaps an age-related (the car that is!) one at that.

In the past few months I've noticed that, when selecting reverse after drive, the gearbox can take a second or two (seems like longer sometimes but it's probably not!) to engage and allow me to actually manoeuvre. As this is certainly a weekly and quite possibly a daily occurrence, I have done my own non-mechanical tests by ensuring that I do let the car stop before selecting reverse and do ensure I maintain pressure on the brake pedal before moving from drive to reverse.

The car was first registered in July 2011, is a MY11 and has 86k miles on the clock. I'm the second owner but it's always been main stealer serviced/maintained and on time.

So, anyone else experienced this with the 6-Speed (or even 8-Speed) box?

Only seen that on a 6-speed with a linkage that needs lubricating.

Is lubricating the linkage as easy as fitting the rear ladder or emptying the ashtray Rolling with laughter

Somewhere between the ladder and the ashtray.

Guessing it's a good read of Disco_Mikey's thread then. Am I lubricating the component that appears in the second pic down in his wiki - http://www.disco3.co.uk/forum/topic31656.html ?

Mine was always the same, seemed to take a few seconds to (what felt like) build pressure and engage drive/reverse

New box is the same, though not as pronounced, but can still catch out 1St gear if you are too quick with the throttle pedal...

Thanks Disco_Mikey. Was I right in thinking the gear linkage is the component shown in pic 2 of your wiki? And if I am lubricating it, what lubricant should I use and what exactly am I lubricating (the shaft or linkage components themselves)?

Isn't reverse selection delayed as standard, so when going from park to drive it doesn't engage? Confused Thumbs Up

Did lubricating that linkage sort it?

Mine did this to me today, trying to do a 3 point turn and no drive in reverse for a couple of seconds followed by a slight shudder and then we started to move. Was a bit unnerving at the time as I was casuing a minor obstruction Embarassed

Mine is the same age as the op. And mine does this. I reverse up a gradient to get on my drive and it feels like it is slipping or not engaging very quickly. Last night I had no drive in reverse and had to go back to park then r and then I had drive. My d3 never did this.
My d4 has 1 previous owner to me and 60000 on it

Is this likely to be the linkage?

I have to admit to never getting around to trying or doing this I'm afraid. Embarassed
