Technical Gears not shifting beyond 2nd / No Reverse (Semi-Automatic gearbox)

[ssray23]

Hi, I drive a Fiat 500 Semi-Automatic 0.9 DuaLogic (2012 UK registration). I had the car's clutch replaced when gear was stuck in Neutral (N) late at night. I called a mechanic nearby and he towed the car to his garage and replaced the clutch. He said he could smell the burnt-out clutch. After fitting the new clutch, he could not complete the reprogramming steps - The car drives fine now but only shifts till 2nd gear automatically based on speed. Car does not shift to higher gears (3,4,5) or Reverse gear- If I accelerate beyond 20mph, gear drops from 2 to N and starts beeping (a dangerous situation while driving). I somehow managed to drive the car back home.

What could be the issue? I asked around on a few Gearbox specialist websites and ASR suggested I might need a new actuator (easily £2000+VAT). The AA guy told me it could be faulty wires inside the gearbox assembly and/or sensor issue (He did a OBD scan and high hydraulic pressure reading was seen). The clutch repair guy suspects it's the hydraulic accumulator, but he suggested getting it confirmed by gearbox specialists / Fiat. Getting an appointment at my nearest Fiat Service Centre is a nightmare - no dates available before April...

Confused. What should I do next?

Thanks in advance
Roy

Hello,

It's a robotized gearbox. It's getting problematic when not properly taken care of. The gearbox with the same principle was installed all over FIAT group makes and called Dualogic, Selespeed, Comfortmatic, F1. And had same problems.

Assuming there's nothing broken the servicing consists of 3 steps, it is described in the MultiEcuScan and also probably in a couple of places in the documentation. However bear in mind that even the original documentation contains errors

There are numerous threads on this forum (and everywhere else, too) as most of the users have same / similar problems. And FIAT is just replacing parts for lots of money.

I was very close to bying a Ducato with this robot, but someone was there before me. Pity. I have a similar (but less complicated) robotized gearbox in my non-FIAT daily and the problem is the same - no one knows how to service it properly, and everyone is assuming 'no clutch pedal = automatic', so everyone forgets it until stuck somewhere. And usually it means it is too late.

There are 3 different fluids involved, one of them being the highly higroscopic DOT4, which needs to be replaced every 2 max 4 years to maintain its properties.

Check for other threads here. Especially the longer ones.

And have a look at the documentation someone posted on the forum some time ago:
