The Puma is definitely a "girl".
You have to be really smooth with your gear changes. Bring the clutch out really slowly. More noticeable when cold going up a steep hill, like the one I live at the bottom of.
I used to drive an automatic Hilux. Took me 6 months with the radio off driving around town to get to know her.....
My experience of 1st to 2nd change is that when the box is cold, I double de-clutch and do so slowly - no grind, smooth and sweet. Once the oil has warmed up - slow changing, finding neutral on the way through, and it's all good too. :)
The box in my Td5 is the same. As well as changing slowly, a momentary pause in neutral before continuing to second should help. Slow and steady.....a sportscar it's not.;)
I mostly take off in 2nd if I can. The only time I use 1st is on an upslope. I don't find my gearbox clunky, unless the gear change is too fast. Slow and deliberate, it suits the character of the vehicle.
Naks, are you sure that wasn't a typo? If I drive in 6th at anything below about 80km/h it feels as though I'm about to stall. Changing up into 6th is only done at about 100km/h.
No diesel Defender has ever like going too slow in too high a gear...
I've seen people do a lot of damage changing down too late or stalling in a high gear. In fact one of the work Prados snapped his 6th gear clean off when a chap more used to an automatic was too slow with the clutch when stopping.
If you do that regularly it might actually be a contributing factor to the problems you seem to have lately.:(

No, I was testing the new gearbox: at various speeds (40kmh, 60kmh, 80kmh, 100kmh), I put the clutch in and shifted between all the gears. Everything is smooth except for 5th-6th below 60kmh. When changing at speed (100-120kmh), there is no grinding, so it's probably due to the low speed.
Weird, in my Td5 I could trash the gear changes and it was super smooth compared to the Puma!Quote:

if your used to driving a series box or a loosened up r380 forget trying to shift that fast. you need about 2/3rds the effort on the shifter for about half a second longer to get the box to shift well. It gets better when its warmed up and the higher gears are easier as well. my advise is to learn to read the traffic and avoid needing to downchange lower than second if you can.
Thanks for all the feedback. Looks like slow and easy is the go - at least I know its normal behaviour.;)
When I first picked it up from the dealer (a Pom - knew his LRs), he said this is how you drive it: Nice and easy in 1st, floor it it 2nd and 3rd.:twisted:
I normally drive from 2000 to 3000 rpm - gear change at 3000, cruise at 2000.
Thanks

Isn't it funny, I always ripped the 1>2 change through as quick as I could in the R380, particularly dead cold when Syntrans was my fluid of choice as it always went through like a hot knife through butter (no resistance whatsoever) otherwise it could baulk.Quote:

This would happen even more frequently in low range, which doesn't happen at all anymore.
I've had exactly the same from dealers every time I've complained. Anyone think a good transmission specialist could improve it? Must say though, I'm pretty used to it and with the VNT turbo giving better low down torque than the old TD5 I had before, I'm now less bothered by it. Even when towing a big load and hill starting, am always impressed by how much off boost torque there is - making fast 1-2 changes less critical.
