Driving an automatic car

    Much easier all round I have found is to permanently disconnect the battery condition monitoring cable and forget about this unnecessary and mechanical wear inducing system.

    Tbh the idea of 80% of traffic being diesel all idling in traffic didn't really sit well with me either. So tried to use it as designed where possible. In the end the car wasn't suitable for a variety of reasons and we got rid of it.

    Wish I'd known what everyone else seems to know before I bought a 2017 Nissan Pulsar 3 months back (70k km on it). It seemed OK if a bit odd until I started driving it long distances at higher speeds and noticed rpm fluctuations and juddering which is getting rapidly much worse. I heard a belt slip screech this morning. I think I'm stuffed frankly and stand to be out 12 grand.

    No idea what to do except find some place that does auto gearboxes and get them to check it. If I can find one. Most places have no idea about cvt maintenance. Gutted frankly.

    Anyway. Avoid Nissan CVTs 😕

    Sorry to hear that, Lucky for me my old Audi A6 from 2003 had the entire CVT replaced at considerable expensive by Audi U.K before I bought it, many if not all Multitronics failed again after replacement or having whatever failed replaced rather than the whole Box.

    My Brother had a 2004 and lucky for him the box failed under warranty, he got it 2nd hand, the car was out of Audi warranty but the dealer he bought it fair play got a new box fitted.

    The Multitronic was a nightmare for Audi, later ones had software that made the box change radios to make it feel more like a manual, it was actually decent but still not a patch on DSG for driver enjoyment.

    Car manufacturers use CVT because they're cheaper to produce which is why I called them Budget Boxes earlier in the thread. Of course Toyota/Lexus hybrid CVT excluded.

    The oil needs to be changed regularly in the CVT and pretty much all auto boxes.

    rpm fluctuations and juddering are a sure sign that the CVT is failing.

    Nissan CVT are notorious for failing.

    You might be able to flog it if it's not noticeable or intermittent, go to a dealer and see if they'll take it as trade in.

    I thought that too after several years and now back in a manual and absolutely love it, plan to keep it a long time so having a manual is less to worry about.

    I thought the majority of powershift were in the early days like DSG ? Most of the issues were ironed out with the DSG 6 speed , they went Dry clutch with the 7 speed and had issues in the early days with those too but they're pretty reliable now.

    A lot of people and dealers don't replace the oil in these boxes.

    Even the Prius MK II had issues , Toyota said the oil was life long oil and this turned out to be bull crap because, funny enough the box didn't fail but one of the motors shorted out that is in the box which gets bathed in the same oil and on the U.S prius form at the time people got the oil independently tested proving that the oil was the cause of many failures , impurities, bits of metal perhaps , don't remember now exactly what caused the motor windings to short out but it was directly related to the oil.

    I had to ask my Toyota dealer to replace the oil and told him the story so he did change it and said it wasn't in good shape, can't remember exactly the kms I replaced it, maybe around 100,000 Kms.

    If anyone has a prius/lexus hybrod I'd make sure the oil is replaced regularly if they don't do it request it.

    Thanks Mad_Lad. I very much doubt the oil has ever been changed in the gearbox. Nissan told me 100k is what it says in their service manual but that sounds crazy. I'll start there - I found a place called Cassidy Motors in D12 who do auto transmissions and they might do that for me. It seems a messy job. If it settles a bit then I'll trade it in sharpish!

    Funny thing, I found moving it from drive to "manual" and shifting to 7 (highest gear) made it much better. But that's just messing. I'd prefer to sort it or drop it.

    Oil change can in some cases fix the juddering but the erratic RPM could be a sign of inevitable failure so get the oil changed as soon as you can, drive it as little as you can in the meantime and if it fixes it get rid of it quickly.

    Oil deteriorates over time regardless of Kms.

    For simplicity you really can't beat manual or EV, Toyota/Lexus Hybrid for automatic reliability, EV has no gear box in the traditional sense, it has a reducer gear, very simple but I went back to petrol manual after 10 years in EV, wouldn't go back.

    I'm at the point now where I intend to spend as little as possible on a car and want as little electronics and computers/screens as I can possibly find, I even have have halogen headlights again because if many modern headlights fail they cost a lot of money and I had 3 headlights replaced in my Id3 but this was related to moisture rather than the leds themselves but they were matrix headlights, they were excellent but if they fail out of the miserable 3 year warranty they cost thousands and need to be coded to the car's main ECU, absolute nonsense, all I will have to ever do is replace a halogen bulb !

    Cars now are just money pits, PCP is a clever con and there are plenty of older cars that are just fine and get the Job done, I don't need to drive around in a high tech entertainment centre on wheels.

    I have a manual car that I plan using now and again on the farm . 4 wd and tow bar .I might have to tax it and transfer insurance as I need it . Kinda looking forward to it myself



  • Registered Users, Registered Users 2 Posts: 1,427 ✭✭✭Mad_Lad


    Yeah, I think modern cars are very appliance like, there's little fun or driver engagement , sure, they are very refined and powerful vs cars of the 80s 90's but they are also big heavy tanks of yokes that are absolutely shite to drive especially SUV and electric.

    Cars are very refined now too so everyone hasn't a clue how fast they're actually going and are speeding everywhere.

    I love being back in manual for the driving pleasure.

    It would be difficult to see over the steering wheel alright! 😉
