Been driving a manual car for years but just got an automatic. When pulling away say onto a motorway the revs go over 4000 revs and it seems to scream until i take my foot off the accelerator then it seems to change gear and the revs go to around 2000. Is this normal for an automatic or am I doing it wrong ?

A few cars have CVT transmission which makes the engine run very fast under acceleration. What is yours?
 
Its a 2019 nissan juke, 1.6 petrol.

Some of them are turbocharged, and it may make a sort of whine when pulling hard. If it screams it may have worn bearings. Turbos can be very sensitive to neglected oil changes or lack of cool-down after hard driving.

CVT transmission was also an option on this model. Does the engine speed seem to vary with throttle opening rather than by road speed?

I expect there are some better recognition points, but I am not familiar with the car. The documentation should say.
 
Its only the second automatic i’ve driven (wife can only drive automatic). The last one you could feel the gear change as the revs went up. This seems to stay in first unless you physically take your foot off the accelerator, although it speeds up to over 40. Feels like i’m screwing it thats why i took my foot off.
 
Does it have such a thing as a sport mode? i.e. push the button and it quickens the throttle response and delays gear change until revs a little higher... and therefore the next question is.. is it in sport-mode by default, as set up by previous user?

Pretty sure this is a CVT Gearbox.
They are a bit unusual compared to a Manual or Conventional Auto.
Had one in a Honda CRV Hire.

Have a look on Youtube for how they drive and work.

It does have a sports mode but its set to normal.
 
+ 1 for CVT 'box.
Only ever rode in one as a front seat passenger ... hated the thing.
I've owned auto's for decades & never found the exact symptoms the OP describes. Yes of course the revs. will rise on acceleration, but the vehicle's forward progress should match them. I'm afraid that auto-boxes, like everything else, are not like they used to be, many don't even have a torque convertor these days.

Had the Honda on Hire for a couple of Weeks and got used to the CVT Box.
On reasonably hard acceleration, the Revs sat at 4K and the Road Speed increased as the CVT Pulley diameter changed.
It feels a bit like a slipping Clutch on a manual.

That's the impression I disliked, despite not actually being at the wheel. I like to be aware of the changes, so long as they are subtle. Both my oldies, with a combined age of 57 years, have ZF trans. & one has the Steptronic facility.
 
I had an old Ford Fiesta with the variable transmission which to start with was really good, I would get on a duel carriageway and engine speed stayed static and slowly got faster and faster, but it seems the cone bearing can wear and cause it to stick, which happened to mine, and then it did seem to jump up the gears and ended up fitting a manual box, which was no where near as good.

Old automatics had 3 speed boxes often with kick down and were not as economic as manual boxes, the torque converter acted as an extra gear, but absorbed some power, the Mini was odd and no engine braking in first gear, and 4 speed, Toyota Yaris had three speed and over drive in 2 and 3 so really 5 speed, and my wife's Jag is 8 speed with a Eco, Normal, and Sports setting, new LandRovers using a 9 speed box, the manual version of Wife's Jag is 1500 max towing but automatic 1800, so it seems today the automatic has overtaken the manual and is far better, a kick down with the Vauxhall Royal I had would spin the wheels coming out of roundabouts so could be rather dangerous, but with 8 speeds that is no longer a problem.

Since there are so many versions of Automatic and Semi Automatic box hard to say how they should work, know wife's Jag also had paddles for manual changing and the Honda Jazz with Automatic box also had paddles, and worked like a 7 speed box, and that was a variable transmission so would not expect it.

I have even driven the old Wilson pre-select. The 2CV had a plate clutch with their automatic, and the big Volvo's I drive locked the torque converter after a set speed to stop it over heating.

As an ex. bus driver from the period so have I ;)
I can't understand the necessity for multiple gear ratio autos. I had a Ventora decades ago that had the GM powerglide with just 2 speeds.
A fast car with 3.3 litres that would return 18 mpg on commuter journeys, which was good for it's day.
These days, with cars built to last the warranty period, the cost of replacing such multi ratio 'boxes outside of that can be financially
ruinous.
Both my ZF's have overdrive/converter lock.

Oh I had forgotten about them, I remember coming to drive one, looked at little gear stick R - D, 1 - 2, 3 - 4 so not going to mess around, so put it in D, all that happened was the doors opened.

Rover 3500 was 3 speed, but first was only selected for towing, as standard used second and third only, but the torque converter resulted in each gear being like having two gears, but losses through the torque converter were huge, a 2 CV could do 60 MPG and a Morris Minor was around the 40 mark, so there has not been that much gain MPG wise over the years, we could do it years ago, however the Fords were rather poor, and most automatics had massive engines, and were really fuel hungry.

I was looking at the spec for my old tow car, and Austin Gypsy around 65 brake horse, 8 forward gears, did around 30 to gallon, today Kia Sorento around 165 brake horse, 10 forward gears, does around 60 to the gallon, OK can't select front or rear wheel drive, and there is no option for a PTO, but I will tell you which one I want to drive, OK could go around the Classic car shows with Gypsy, select front wheel drive pull up hand brake and pivot on rear wheels, but why would you want to?

Yes I pulled caravans up Sutton Bank with the Gypsy, with a gear to spare, can't do that with Sorento, but only because no longer allow to.
