So then, as far as i can tell every puma has a problem in that the clutch wasn't really designed for that gearbox, which is linked to a hand-me-down engine. and as such theres and obvious clunkiness changing gears, just wondering if anyone has found a way to change gear in such a way which makes it less obvious? or if there is in fact a 'fix' or some other method of fixing it.
clutch is <5k old and it was the same before, and was the same on my previous 2.4 90 so either its something i do (and my dad) when driving or its just a fact of the puma. any advice or insight would be appreciated Cheers, David Land Rovers of all shapes S3 onwards… Daily is a 110 V8. |

yeah I've found often slower is better.
interestingly too, gear changes seem to be smoother the more I rev (2.4-2.5 seems to be nice but its excessive around town or when in traffic where the clunk is most pronounced) oh well, just a defender thing  Cheers, David

I don't have a problem driving mine but my mrs struggles to keep it all smooth, so it may just be technique, i was told never to use the clutch as a switch on a defender and to be very gentle and slow with engaging and disengaging the clutch, couple that to the fact i'm never in a hurry and it seems to help me.

I'd imagine it's all down to the bite of the clutch and the small amount of slack in the drivetrain. I think lower gears are worse especially 1st to second and second to 3rd other than that not too bad. ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️

Yes, me too, and worse when cold. I find I also over-rev slightly in the lower gears and then change gear slowly it's OK. Uphill with trailer is worst, because the car slows down so much whilst doing the slow gearchange that if you don't over-rev in the lower gear, then it labours in the higher gear. I'm not a fan of revving a cold engine, but luckily my first uphill bit is a few hundred metres from the house, so I'm rolling by then. Gearbox oil is the standard Castrol (although I have changed it). I think I'll try other lubricants, or maybe an additive next time (IIRC DGardel recommended some ceramic additive which has miraculous benefits) Defender "Puma" 2.4 110 County Utility (possibly the last of the 2.4's) |

I've found that not rushing the change and squeezing the throttle slightly just as I start the change smooths it out -- but I've no idea if that's good driving practice. I'm sort-of-getting-used-to accepting the moment of disengaged drift you get during the change, but that may be part of it being a Defender, not a Maserati. 2009 110 XS Station Wagon

Don't rush it, adapt the speed of change according to the temperature of the box, and double-declutch down (and up if necessary).
The Puma box needs a rediscovery of the old skills for changing gear! It is much more satisfying when it works than a modern can't-go-wrong gearshift. |

The Puma also has an anooying habit of holding revs a bit high during gear changes, (supposed to reduce drive train clunking) but it's not clever enough to match itself to your driving so sometimes it doesn't help at all.Cheers,

Have never driven the 2.2 model but in other Defender models I have driven around doing clutchless gear changes - that is one way of getting your timing and co-ordination right - or you get very noisy mechanical feedback.

Probably got salt water in from recovering your rib
Your OP says it all a mishmash of parts not up to the job mine is the same  |

An easy way to help with smoother change is never let your foot fully off the gas. When changing down give it a little blip.
Everyone says change slow I don't agree. I think you can change as fast or slow as you wish. Changing gear is about matching the revs of the engine to the gearbox. The engine needs to be running at the same speed. If it clunks it's telling you your not doing that right. I call it the c***ometer. It's telling me come on rob get your act together.

Cuthbert I agree with you. If you drive clutch less you have to match the revs else it just doesn't go into gear.

Some say this, some say that, each one is different but drive it like a eurobox saloon and it will clunk. Steve.

The stealer had mine for a week but fixed that damn clunking/backlash. Now it's really good and even the Cook might try driving it now.
