Technical 2017 2.3 150hp - transmission

[Omolland]

Noise from gearsystem when shifting to lower gear. Red message alert in display: «Transmission unavailable»
Next day it was able to gear with no alert.
Even though the camper was transported to garage. They found lot of dirt in gear-shift system. Was drained and flushed 3 times.
Back on the road - after 400 km alert was back. When starting and tried gearing, red alert «gear unavailable» appeared.
Contacted workshop again, their conclusion was to change the Comfortmatic gear-shift system unit.
Now awaiting parts to arrive..

Camper is a newly bought 2017 Solifer, first time registered in 2019 with guarantee from dealer.
Has only 16000 km on counter.


Any similar experiences?

Yes, Comfortmatic from 2017

Sorry, I haven't seen one of the lines when you wrote it's a Comfortmatic gearbox, or it has been added. Nvm.

It's a complicated system, workshops tend to replace it (as they are earning a lot of money on it), but most of the time it requires precise and regular servicing. It is operated by 3 fluids, one of them being DOT4 braking fluid, which is highly higroscopic and should be replaced every 2, max 4 years, otherwise it loses its properties.

Then, the servicing consists of 3 or 4 actions using MultiEcuScan that have to be done in a precise order.

There are numerous threads in here (and other forums) on the Comfortmatic / Dualogic / Selespeed / F1 system (it is sold by the FIAT group under those makes). Especially the one that has 'the one and only repair guide' in the title seem to be interesting.

 

[Omolland]

Yes

Here's a FIAT eLearn manual on the Selespeed in the Alfa 156. The system logic is the same, the location of the parts and their size might be different, but it should allow you to understand the system and its servicing:
