Hello All,
I have recently bought my first car (FIAT Grande Punto 1.4L Petrol 2009) with Dualogic (semi-auto) transmission.
At first the car was running great (apart from issues with starting due to old battery; now replaced along with new starter) but a short time later it started leaking gearbox oil. I had the shaft seal replaced and new oil put in, yet since then I started hearing a high-pitched whistling/wheezing sound when accelerating on gear 3 (normal mode) and gear 4 (ECO mode). Few days later my Punto started to jump out of gear (I think) when on gear 3 and now the wheezing/whistling sound can be heard also on gear 2.
The first time it occurred I was driving uphill on gear 3 when the revs suddenly have gone up to the roof and the car started to loose speed. It's as if the gear slips out to neutral though the screen shows it still being on 3. Only once (the first time) the system started beeping...
One of the mechanics (different one) said there is still leakage seen between the engine and the gearbox and that probably only the external shaft seal was replaced.
The fluid was filled up again to see how badly it is leaking over time (without incurring the cost of removing the whole gearbox) and although it is still dropping out of gear (between 3 and 4), it is not as aggressive as before. I'm guessing it's due to having more fluid now.
Additionally the gear change is occurring slower than before (I can rev it up higher before the gear changes). The issue is also happening when using the manual mode.
Does anyone know what the problem is and how to fix it? Would fixing the leak possibly resolve this? I'm asking as I'd rather not put money in costly repairs if it's pointless at this stage or if the gearbox fails in a month completely. Also seems like not many mechanics are familiar with semi-automatics or Dualogic itself for that matter (at least in my area).
I would be most obliged for any advice provided.
Kind regards
Zak
