Technical Fiat 500 Dualogic understanding this system and how it operates

[Digger Downunder]

Hi everyone... There seems to be a lot of confusion with how the Dualogic Trans works. First let's clarify what we are dealing with it is not a Automatic Trans... It is a Manual Gearbox with a hydraulic system to operate the clutch and gear shifts it has its own special Fluid NOT to be confused with the Gearbox Oil.. This hydraulic system operates at high pressure 40 bar + and requires its own maintenance ( often neglected ) this is where most problems develope with the system.... This post is a Basic explainition of how the Dualogic operates.. In future post I will cover some tips. Hope this was helpful......

This is a much needed item. Its a good system to use but frankly the adverse comment on here have meant I wont consider a car so equipped. I have always thought it cannot be that complex and it should equally be possible to repair mechanical defects. Auto doc have been offering some parts recently so if you can share some good info it will be useful to many I am sure.

I'll second that.

Ideally we need input from folks who've successfully stripped and rebuilt these units.

There's a list of adjustments / calibrations in MES on Dualogic / Selespeed. But as far as I remember the proper order is crucial...
