You are right to change it to a 30 grade but in real life it will work with any oil.

I've lost track of the problem now - is it still that you can't engage first gear?
If so, don't worry, just use second as the fluid flywheel enables you to get going in any gear. I never use first.
You can sort the linkages out over time. They are very tricky and very sensitive, it will drive you mad.

I'm sure somewhere along the line somebody has said to pump the gear change pedal in every gear to take up any adjustment. In my experience you need to do it 30 times in each gear but I remember reading in a manual you need to do it 100 times in each gear - which seems completely excessive but you never know.

Finally - have you changed the gearbox oil and flushed it?
I started a long debate on here a year ago as the Service Manual says to drain the gearbox, fill with 5 pints of paraffin, run the engine at tick over with the gearbox in neutral for 5 minutes. Then drain the paraffin and refill with 5 pints of 30 grade oil. This is to remove all the brake band deposits accumulated on the surfaces and free them up. If this isn't done then the bands don't grip.
I said 'Paraffin! That is crazy, I'll use a modern flushing oil' - but the debate was over the flushing oil not doing the job as well as paraffin and also some of it staying around after draining and contaminating the fresh gearbox oil. OK so I used paraffin to flush and then fresh oil.

Hi Graham,
thanks for your advice.
I have not resolved the first speed engage. But as you write, I can live without it. I will solve this problem after the summer when I can not go on trips. Gearbox oil was replaced, but the gearbox was not flushed with paraffin. I'll try it too. That might help. It could also solve the weak reverse speed.
Now I am dealing with the problem of spontaneous drive at idle speed (second speed engage). They also told me from one car service that it was normal. Time will show. But I rather check the brakes.

Yes I have the same. If I start the car without first checking that it is in neutral, the car will move off. This has caused me to crash into my own garage door causing £1000 of damage - to the door, the Daimler didn’t have a scratch!
Make sure your handbrake is in great condition!

Or make sure you always start in neutral.

Concerning your “weak reverse gear”. From my own experience may I suggest you check the gear change pedal isn’t impeded from returning fully after it is pressed. Ranald

Hi Ranald,
Oh, another small problem, reverse speed. I have to check it out. Is the gear change pedal somehow adjustable or fine-tuned? At some speeds, and sometimes it happens, after the gear change pedal is released and a few meters away, the pedal is still jumps up by about 1cm. But it's not often.

Hi,
I tried to set slow running. Unfortunately, even at low rpm, car starts to run.

Something is wrong. Even at iddle speed I have to brake a lot so the car does stop.

How are you checking what your idle speed is? The on-board tachometer could be inaccurate. Tickover speed should be 400rpm to avoid creep.

Hi Andy,

Thank you for the advice. That's probably true. I did not think about it. I will try to use the external tachometer. It is true that rotations per internal tachometer fluctuate from 400 to 1000 rpm. When I shot the video, the tachometer shows 400 rpm, so I trusted him. I'm just a beginner and I'm grateful for every advice.
