hi everyone.....
has anyone experience jerking of the car when moving off from standstill as well as reversing when using the Duologic gearbox? Doesn't happen all the time, just 5 out of 10 times i drive......anyone sharing the same experience? anyone has any idea why the car is doing so???
cheers

Only happened to me once after the car had been standing for 4 days outside in sub zero temperatures.

I wonder if the oil in the box was cold or the clutch plates were sticking?
 
hapen to me lately....especialy when i am cruising at a crawling speed until to state the engine almost cut off.
add come addactive to the petrol tank...so far have not encounter any of that yet.

do anyone have any idea where the cpu for duologic located? Any repair manual on duologic?

i have repair manual on other off shelf semi auto product. the off shelf ones able to control the speed of clutch releasing. just wondering whether i can do that on duologic
 
I also have a dualogic, but don't have the aforementioned problem.

I do however notice that there's a very specific position of the gas pedal that'll make the car stutter. At some very slow speed it doesn't quite seem to know how to handle the clutch: too much, too little, too much, too little.. I suppose it's just not eager to drive with the clutch plates 'rubbing' (don't really know the right word). The 'fix' for this is simply to go a bit slower or a bit faster :)
 
yup...agree with you but lately it become more obivous...surprisingly when i add addactive to petrol the obvious one disappear but the earlier one still there but less.

agree with what you said do not press the accelerator too little...

I'm driving a new 06 Punto and have just experience the same problem of juttering as well. Similar to PandaUK, I left my car sitting in the garage for almost a week before noticing juttering.. I don't drive it very much so will have to drive it a bit more to see if the problem is still there...:eek:

I get this too - it's worse when more people in the car as the momentum of more people accentuates the jerkiness. It does it with me when engine is warm, and when car used every day.

So is this juttering normal? :confused:

Seeing how many people confirmed it, I'd say Yes.

At a very slow speed, with a cold engine, the clutch can jutter, and it'll worsen because 1 'jutter' will make your right foot jutter as well, resulting in the actual juttering! But it doesn't really disturb me. I'm still extremely satisfied with the Dualogic gearbox and would recommend it to anyone.

Is this not an oil pressure related prob?. Something rings a bell about this prob.

I really doubt that it is anything serious. I've used my Panda today for the first time in 2 weeks, and no juttering what so ever.
 
I agree with Soepy my only time I had noticeable juddering was after the Panda had been left in cold weather for four days. Cold oil, sticking clutch plates?

I'm on my second Dualogic Panda and it has to be the best auto/manual box for the money until I can afford an Audi or Porsche!!
 
Okies I've a really stupid question (I've been an auto driver all my life until now with the Dualogic so bear with me): I was exiting a shopping centre going a steep 'hill' whilst I was in second gear. Then the car slowed down so much so I manually shifted down to first gear, then the car jerked quite violently (until I reached the top of the 'hill') - have I done any damage to the gearbox?
 
i noticed that you can enggage 2nd gear if you enggage it from stand still. give you smoother ride but less power
 
Hmm.. but can anyone explain why there's a slight jerk when changing from first two second gear? This usually happens after a few days of not driving the car, and the problem goes away after about 10 - 15 minutes of driving.. any ideas? Thanks!
 
got same problem (Juttering from stand still) the problem being is is that the input shaft bearings are naff and seizing the gearbox (noise from gearbox but less so when clutch pedal is pushed in) the only solution is replace the gearbox for which im not happy. the common thing people do is use 80w-90 in the gearbox dont you should be using 75w-90 semi synth the use of 80w-90 is too heavy for the fragile and very small gearbox as for dualogic the senario is worst case have the box checked at fiat could be eletrical

Hmmm.. so you're saying if the gearbox is a normal manual gearbox, then it needs a complete replace, whereas if its a Dualogic then get Fiat to check it?

were did you hear that absolute nonsence i have an uno wich has run out of gearbox oil twice and also has had alsorts of oil in it whatever gear oil i could find in the garage i work in at the time to fill it with to avoid having to pay for some and it is still as good as new and i dont milk it ether double de cluching eveywere and generaly driving like a lunatic also it has had 2 learner drivers in it including my self

so in my opinion the 514 box is buletproof

as for jerking when seting off well this is all down to cluch wearing quicker than the auto ecu expects it to

ie as i'm sure you will all agree people with the formensioned problem will all iver be driving like nuters or live in very steap areas of your respective country howether if you take your cars to your dealers their is a cluch learn prosedure wich is used for the fitment of a new cluch wich can also be used to get rid of the jerking when seting off it is a simple prosedure to preform and should be proformed under waranty if your car is still under waranty

at the garage i work in we have put claims threw for time spent doing it and got paid for them by fiat

so if your dealer is reluctant to do it for free well tell them you have heared of it being done else wear for free i fink their may have been a service news for it a few months ago not sure

also the 188 puntos have the same problem same engine and gearbox
