Driving a Puma smoothly
Forgive the post, but l am completely new to "Puma" Defenders having only owned TD5/300tdi

lam struggling to drive it smoothly, when accelerating away it's difficult to make smooth gear changes without clashing of the transmission.

lt seems that you need to get your foot off the clutch as soon as possible because riding the clutch (such as in slow moving traffic) results in very jerky progress.

l've looked it up and people were complaining about this when the vehicle was new back in 2014.

BAS say their remap removes "90%" of this jerkiness at low speed. Obviously that will be my next move if l keep the vehicle.

Also l did change the rear drive members yesterday, from past experience they are usually worn and it was the case here, about three inches of play at the wheel rim.
After replacing it was down to one inch of play.

And it is a bit better on the road today. The output shaft is obviously another item, although this one seems fairly good, once you've got the clutch out it's quite smooth on and off the gas without the "clunk" that most Puma's that l test drove had.

l've found that it's often much better to start off in second gear particularly if you're on any kind of downhill. But l imagine this will reduce the life of the clutch.

The Defender has done 49,000 miles.

I had a lot of kangarooing on my 2.4 2007 110 when I bought it last spring. It then had 130000km.
Since then I have:
New drive members all around.
New bushes all around.
New A-frame ball joint.
New oil throughout the driveline.
One UJ replaced.

Before I bought it the clutch was replaced and had new suspension all around.

It now drives the best I've had a 2.4, but there is still a little jerkiness but nothing that bothers me. The biggest one was the upper link bushes.

Recently though, me and my wife started to speculate that one of the root causes to the jerkiness is the lack of sound insulation in the engine bay. We noticed that if you rev it to 2700-3000 rpm you almost always get a good gear shift. But especially in slow city traffic it just doesn't feel right due to the loud roar from the engine. It would be interesting to hear from someone who have added sound insulation to the engine bay, if their driving style was changed.

Hello


Mines poly bushed all round and a remap, I do tend to start in second.... I know not the best thing to do, I find 1st far to short it town. Its on 110K so still seems ok.


Drives more than fine like this. I am 'gentle' with it.


I have other issues that I am addressing but thats the diff / tannsfer whine... Very Happy

posted this info in your "tuning thread"

regards "kangarooing" then if you rest your foot on the clutch switch it will try and activate the anti-stall and can see things a little less than smooth
I also had various issues when first purchased which in the end turned out to be a faulty clutch switch and is transformed once it was replaced

You mention “transmission clashing”. Do not rush shifts. It is a truck, not a sports car. Clutch in and pause for the revs to drop before shifting. Or, you can double clutch on the way up.

I’ve not driven a puma, but people say that an atb centre diff kind of preloads the transmission and takes out the driveline slack. 1983 110 automatic OM606

Could be a case of faulty clutch switch.

I did test disconnecting the clutch switch and also shorting the connector on my 2.2 (you will find quite a number of posts here saying to short the clutch connector - unlike a Td5 where the connector should be left open), but neither case gave me a good or smooth running of the engine.

If I recall correctly-

With clutch switch disconnected - the engine maintained very high revs between gear changes. Throttle response was normal. I suspect that this would be the state of the switch when your foot is off the clutch.

With clutch switch shorted - the engine rpm dropped very quickly, faster than when clutch switch was connected, but throttle response became too sharp and led to kangarooing.

So in short, check that your clutch switch is operating correctly. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

lt seems to be working because if l hold the clutch pedal down a little, the engine is less smooth, so something is changing.

The issue is, and l am sure this has been discussed to death already, when changing up through the gears if you bring the clutch up too slowly it can chatter and "kangaroo". lf you bring the clutch up quickly it doesn't do it but more often than not you get a lurch as the engine revs match your speed.

Sometimes l get it right and sometimes not. l suspect a new clutch and output shaft would improve it, together with a remap.
But that's £1,500-2,000

As suggested above changing gear at 2,500 rpm is better, but it's unnecessary in traffic and probably uses more fuel.

Don't drive it like a car, don't slip the clutch, don't rush the lever movements and don't loiter with the clutch movements. Double-declutch both up and down the box and change from first to second at little more than a fast tickover. When pulling away in first, unless on a hill, don't touch the throttle until the clutch is fully engaged.

Most of which equates to develop mechanical sympathy and drive it like you'd drive a 1950's lorry, which, in many respects, is what it most resembles.

I have always ( except when towing or hill start) used 2nd to pull away.
Its a tip I got from the Land Rover Experience Guy back in 2014

And like the above say.. a direct but sympathetic change with a bit of double declutching works wonders.

I have had a Puma since 2010 both 2.4 and 2.2 and never had a remap.
Its just not for me..although I can see for some there are benefits.

Eventually you will drive it without thinking as it all falls into place.

Once you’ve eliminated as much slack as possible you just have to get used to it and adapt your movements.

There is huge variation so some vehicles are better than others, in the course of work vehicles I had a brand new 12-plate which was absolutely horrible and a 10k-mile 60-plate which was pretty tight.

In my opinion none are as nice a change as a Tdi/Td5 but it’s just the way the gearbox/clutch is it seems.

Completely unhelpful to Lightning, but your last sentence is so true. I have in mind future proofing and streamlining my 90 ownership from a 200tdi & 300tdi into a Puma (again!) which has many advantages including the 6 speed, but the earlier gear change is so nice Confused Rob

It would be worth checking the state of the clutch, too. If the driven plate has lost its springiness it will take a lot more dexterity to drive smoothly. Plenty of threads on the Puma clutch death rattle.

Unless you're supremely unlucky the MT82 gear change should be much nicer than the agricultural change on the R380 (but noting that there are bad and good examples of both).

Clutch switch can be involved a lot, Bear in mind there is I think about a 20% or there abouts momentary torque cut with the clutch switch.
When it’s in good condition there isn’t an issue, but as they get old and worn they can get sticky, when it gets really bad you can get rev hanging.
In my experience the rear DM’s and the clutch switch has the most effect, if you’ve got poor rear damper bushes can make things wobbly too when pulling off if badly worn. ____\We|Will|Win/___

Mine is the same. The only way i can drive smoothly is to change every gear at 2000 rpm and not touching the throttle until fully off the clutch pedal. Having replaced bits and bobs over the years nothing was every worn but I've managed to nurse it to from 50000 to 86000 miles and now the clutch is making more rattling than normal so its probably clutch time! joy 1953 80"
