Stalling an auto 'box

Has anybody else managed this? I did my first artic shift last night, after passing my test in a wagon & drag. Went pretty well. But got back to yard, putting trailer in its place, I managed to stall the truck :open_mouth: . The dude that was with said he’d never that before.

So was wondering if any of you lot had managed to stall an auto 'box motor…?

Ā£5 says it was a MAN

I’ve managed it in a MAN too. Usually at a roundabout. Always when you’ve started to go, but have to back out of it cos you see a loony flying round the roundabout at warp speed. Seems to confuse the truck, resulting in it stalling.

Not really a stall but ive been stuck in traffic and tried to pull off at the exact moment the auto engine shutdown kicks in.

I have with my scania when I was stuck in snow, I choose too high a gear to pull off in.

Both Scanias own box and Arsetronic (one of its many failings) can stall if turning tight fully loaded and you don’t lock it in gear, the thing changes up a gear and modern engines can’t cope with too low revs.

As Damoq above, at junctions too Arsetronic can’t cope if you have to stop then go again its buggered.

It was an MAN. Not on a public road, luckily. But in the yard, slight incline. Was trying to creep forward, so veryy little throttle. So little in fact, it stalled.

Happens allot on my daf but been told the gearbox needs 're mapping

Managed to knock an autobox out of gear before.

Misheard?, they probably said it needs replacing with one fit for purpose… :laughing:

nice bit of skirt in the offside lane?

Yep, bit embarrassing to be fair, especially having to reach down and turn her back on again after a failed launch.

Yep. In a DAF. Starting to move off then having to stop again. Also when checking the trailer is properly hitched up. As Dipper Dave would put it, ā€œaborted take-offā€ and when ā€œgiving it a tugā€.

Done it on an MAN a few times myself. Each time was on a roundabout that didn’t have a clear view of traffic approaching from the right so just as you think all is clear and good to go, and you wait ages for the truck to actually move, someone suddenly bolts on to the roundabout and you have to abandon your attempted pull out, just as the truck finally decides it will lurch forward after all. The incredibly slow acting gearbox gets confused, throws a massive tantrum and stalls, leaving you sitting there like a prize pear.

At the risk of upsetting some most of the problem is down to driver error , auto-boxes require a little more care from the driver , ie, a check of the illuminated gear indicator will tell you which gear you are in , most drivers will know if the particular gear is correct , if its not then simply use the manual override and engage the correct one for the conditions , I have had the same problem with the I/shift which I found on several occasions was not any better than the others .

After you mate.

My MAN ridged doesn’t stall but some times the computer goes do dally and won’t change gear and comes up with error message and I have to turn off and on again

It was my first time driving it and had done 300+ miles in it without drama. The gearbox appears not to like low speed enviroments. The rigid I usually have has never stalled mind

Stalled a 12T auto MAN rigid attempting to pull away uphill on full LH lock with the front O/S wheel on the grass verge. Restarted it and tried again. Stalled. Tried again. Stalled. Tried again with huge amounts of throttle - managed to keep the inside rear wheel spinning enough for it not to stall. Didn’t much like the burning smells coming from the clutch. There was no lower gear to select - it was already in first.

And i humbly thank me learned friend for the opportunity.
My humble apologies for being lax, was watching the last Sleepy Hollow of the current series with my fair maiden, Ichabod is doing his gentlemanly best.

Its one thing when the autobox fails to proceed, they all do that now and again and always will because its impossible to program every single variation into the computer in charge of the box.
It’s entirely another when the combination of an unfit for purpose gearbox and an engine lacking in lo revved torque combine to stall the engine immediately after a failed start so admirably described in some of the posts above, this doesn’t tend to happen with Volvo (also used in Renualt) boxes because they are the exception to the rule and are fit for purpose, and their engines tend to have some stall rev torque still…maybe the EU boffins can make sure that’s programmed out at Euro7 i have no doubt they’ll do their best… :unamused:

I as some others on this forum drive the vehicle constantly in manual when loaded, and most of the time when empty, in MAN’s when empty in manual the box will default to 3rd as start gear should you come to anywhere near stationary (it usually starts in 5th in auto unless you come to rest uphill or are starting from scratch), so a combination of auto and manual override at junctions has to be used to make any sort of normal progress that a lorry driver who takes a pride in their work would find acceptable, again dropped into manual as soon as moving.

We are lucky in that at least we still have the Profi (manual) option on our Arsetronics, where some fleets have auto only and indeed on the euro 6 DAF i was unfortunate enough to drive a few weeks ago…DAF what have you done…the bloody gearbox reverts to auto and bloody eco within 30 seconds and even if you lock it as best you can in M, soon as you use the retarder it triggers return to auto.
Its utter garbage, can’t believe its from the same maker of the last one i had, a CF 460 manual which was a cracking little motor, and i still see it now and again with its new owner or driver passing everything on the road.

Indeed something myself and one of my compatriots have been monitoring is clutch and other failures on the fleet MAN’s, interesting that the manually driven vehicle is not only better on fuel overall its the only one which hasn’t yet needed a clutch and is proving less troublesome by a fair margin, this vehicle also gets warmed up and cooled down and will till it’s no longer mine no matter what the bloody suits say otherwise.

Why do we drivers, or most of us anyway, know that many of these auto gearbox designs (Volvo excepted) are rubbish and the only way to make them perform efficiently is to take over and drive them ourselves, yet the companies keep agreeing with the sales bod and accepting them, makes a mockery of them being called auto, try steep hill climbing with many makes at full load weights and you’ll end up stalling the thing unless you drive it in manual.
