It is a consultation about the semi-automatic transmission of the foreign car.
The semi-automatic transmission made by Magneti Marelli is "Selespeed" when it is on Alfa Romeo, "Dualogic" when it is on Fiat, and "Dolce Far Niente (DFN)" when it is on Lancia is a semi-automatic transmission system of Italian cars.
The transmission body is the same as the manual transmission and has the same dry clutch as the manual car.In short, it is a mechanism that the hydraulic robot performs the shift lever and clutch operation on behalf of a human.
Hello, Please teach me by all means.
Judder comes out occasionally when transmisson is cold.
In addition, at the time of deceleration after running for 2-3 hours, when the automatic shift down from 3 to 2, a shock of the sound comes out.
I have added selespeed fluid into my owm work sub-reserver tank to ensure that there is no shortage of unil opals.
A year and a half ago, as of 63000k, both mission oil and engine oil have been replaced.From there, I still run only about 4000 kilometers.
I was setting Clutch Travel to 27.9mm, after calibration by using Multiecuscan, it is a shift shock recurrence at 240 km running.
What are the assumptions about these?
The worst, I am thinking of synchronizing mechanism corruption.
I would greatly appreciate your response.
I sympathize with your car's symptoms, and understand that you are in a lot of trouble.
First of all, it is not confirmed about the damage of the synchronizer mechanism that you are imagining, but It seems that The selespeed is designed so as not to cause excessive shift change so that damage does not occur to the mechanical mechanism.
Whether it's a cold judder or a shock when shifting down during warm weather, I feel that the clutch operation is not smooth.
The operation of the clutch, as you can see if you have experience riding a manual mission, especially near the meat point is required very fine control.
There is a difference in the feel at the time of meat between warm and cold, and especially when putting it in the back gear without the synchronizer mechanism, the shift lever operation is hard and may not enter as you think.
It is natural that there is a difference in the connection of the clutch because it is said that these things that humans have fine-tuned sensia are executed by simple (although I think it is quite complicated).
"My Cele is quite good and troubleless from the start of riding" in the side, the shift returns to neutral while driving, does not enter at all in the 1st gear and R gear, also, such as no longer missing while entering the R gear, There seems to be a selespeed which is often hit by trouble, too.
In recent years, there is a light car equipped with the same mechanism as the Selespeed called AGS in some of the Suzuki, but the half clutch is longer than the product of Marelli, and the shift operation is also slow.It may be filling in the error of the machine, or it may simply be room for improvement.
If Marelli has made severe settings to get the pleasure of driving a car and sacrifices the stability of the product, I feel that the difference in clutch movement as described above is appropriate.
Although the adjustment of the small hand hardly improved, the selespeed unit, the clutch body, and finally, when the controller was replaced in order, it was clearly solved at some timing.Only the repair of such a touch stands out as Web information.
I think that the supply of parts is the age of the car which has become a delay.With the use of good recycled parts in mind, it seems to be difficult to make a short-circuit or short-cut, short-circuited either, whether to carry out an exchange inspection as much as the budget allows, or to stare at the multiecuscan data monitor patiently.
We look forward to hearing your questions and consultations.We will answer simple questions that you can't hear anywhere for free.
