lt's only if l don't get the clutch and engine RPM right.

l am actually getting better at it. First gear is best avoided unless starting on a hill as you almost immediately need to change to second anyway. And then you lose the momentum you've gained, waiting for the engine RPM to drop so you can engage second without crunching.

Double declutch first to second.

Blackwolf must have a faster left foot than me, or better hand-foot coordination, to manage a double clutch before becoming stationary again. I’m not saying it can’t be done, just that I’m not there.

Lightning: I’ve started to pay closer attention to my gearshift since this thread started. As I wrote in an other thread, I’ve had a lot of clonking when shifting but have now reached a point where she runs like a ’normal’ car. I too tried different strategies to meet the clutch with a light touch on the accelerator, to match the rpm. Sometimes it worked, sometimes it was much worse.
Now, with new DMs, new bushes and new oil, I don’t touch the accelerator until my left foot is off the clutch. No clunking no jerking. Smooth! And no upshifting below 2500 rpm.
What is it like if you cycle between drive and coasting on a flat road? I had the feeling that there was tremendous amount of play in the driveline and that the rear axle came kicking me in the back upon coasting. Upper link bushes made the biggest difference. Now I almost don’t feel any play and cycling between driving/coasting doesn’t produce any jerkiness or clonking.
I can’t say if you have the same problems as I had, just that once you find yours you’ll be able to shift without problem, even if it doesn’t seem like that right now.

It possibly helps that I've been driving vehicles with no synchromesh fairly regularly for getting on for 50 years, so double declutching both up and down the box is second nature. With the Puma's superbly low first gear, a clutch brake might have helped but it would baffle 21st century drivers! Very Happy

If you want a real gear change challenge try the (non-synchro) gate change on an early Scammell or similar.
