Thread: Disabling the weird Puma revvy thing.

Wally, any chance of some video. Can you use your phone.

Lagerfan, know what you mean. I felt like a real goose when I got mine. Apart from a lot of over revving with gear changes, I also did a lot of driveline clunking, occasional kangaroo hopping and clutch slipping. I found slow gear changes and slow driving generally make for a smooth defender.

It has taken some time, but to me it seems a timing thing. Which is a pain if you have spent many years with different timing.

I've adjusted my driving and it doesnt really bother me now. Just take your time when shifting but not long enough that the revs drop and then you get the kangaroo again! lol

I'll try and take a video later.

Thanks for the tips guys, am noticing slow and steady wins out for sure when driving "George". Another top tip I found (here on AULRO.com of course) was to treat the gear changes as a deliberate two movement process, i.e gear to neutral, neutral to gear, that seems to really help with the klanks and other general schoolboy error stuff when getting used to our new ride, it could be it just slows you down to the Defender's pace, anyway it works!

But still think Wally is onto something here, changing at low speeds I'm sure we see some revving going on resulting in occasional kangarooing and unnecessary gear changes when at those speeds & revs (controlled by the human foot!) it should be smooth as. Could it be the anti stall thingamajiggy? I do tend to have a light touch with the revs???

I might add to, my old diff, the original one was a bugger to keep quiet. Perhaps 3 or 4 changes out of 10 were quiet, the rest just banged. This seemed to exacerbate the sloppy gear changes in my book, but perhaps vice versa.
I have a different diff now that was set up by a specialist diff shop. Now days I really have to bugger up the change to get a quiet thud out of it. Maybe the accepted back lash and drive line slop that LR say is normal has a bit to do with difficult gear changes.
Honestly, every change is smooth and quiet now.

Yeah, probably a good point. The backlash does seem to contribute. But I have at least as much backlash in my Tdis and smooth gear changes are easy in them. But then you could argue that after driving them for eighteen years I've had plenty of time to learn how to get it just right.

I have to say that having a properly setup drive train by a specialist taking all of the slack and backlash out makes a massive difference to gear changing. I used to notice the slight increase in revs but I am so used to it now it doesn't bother me at all as the disconcerting thing was the sloppy drive train.

Drivetrain on mine is a little sloppy but quiet, clunk-free gear-changes can be had with a deliberately slower change and also an increase in revs prior to gear engagement

... not possible when off-road!

Defender2 - View topic - Clutch switch and throttle responce

any of you tried this???

apparently as grappler has mentioned, shorting the clutch switch wires disables the revvy shifting thing while keeping the anti stall going when at low speeds... is that correct?
