Hello,
Noticed on a few 4C's (mine included when new) the TCT oil stands low. After priming, there's almost no oil in the reservoir.

How to check: cold engine

Open door,ignition on. Open boot and leave it for a while. Oil lowers when priming and goes back up after a while. When oil stands on minimum or below the mark = no good. When low oil in reservoir (below the minimum mark) and priming the reservoir is almost empty.

Refill procedure:
Open door,ignition on (primes and the tct oil lowers) and check reservoir. When fully empty refill until the MINIMUM MARK immediatly. Wait for a while and the oil rises to the top of the reservoir.

Please test this procedure for yourself, maybe this is not the right way to measure/refill the reservoir. I've done this to my 4C in the begin when purchase. (Garage said there was no problem when contactin them about this).

Bougth new with:
low tct oil
low coolant
to much engine oil (above top mark dipstick)

All i want to say is: please check the above on your 4c...



Tip for people with a 'yellow' unreadable reservoir: put it in a dark room and shine behind the reservoir with a strong light for measurement.

Please when incorrect , i'm here to learn 🤓

I didn't know you could check the TCT oil?? We are talking about the Twin Clutch Transmission, correct? I thought you had to go underneath the car and check at the fill hole.

...I think most knew what you meant. Thanks for the observation.

Procedure for level checking (if I understand the topic correctly) is on the 4C cloud.

Thanks for this; had not done it before as I did not even think about it but just went to the garage and did it. It is quite difficult to see through the reservoir but I would say the level on my car sits around 3/4 of the reservoir; which I checked by unscrewing the cap the "measuring" with a cutter.
I am assuming the MIN mark is the bottom of the reservoir (did not see any mention to the MIN mark in the manual).

Please check with a strong ligth behind the reservoir and dim the garage ligths. Put your hand on the intercoolerhose and shake the car gently. Now you can clearly see everything (min mark is towards you and oil level)

Reservoir location within engine bay, for reference (because the images on the procedure are too close in to actually identify the spot well).

Only thing I could find remotely close/easy to order was Ravenol which meets the spec in the manual: Amazon.com: RAVENOL J1B1010-001 Hydraulic Fluid - GHA-F Gearbox Hydraulic Actuator Fluid (1 Liter): Automotive

Petronas was $$$$ from over the pond. What have others used? I just want to have some on hand, I'll have to check the level this weekend. Thanks for the info!

[EDIT] Mopar OE Fluid P/N is 68092638AB

Wow, I did not know about this! And I'm a "read the f'n' manual" kinda guy!

Maybe contact Alfissimo International for the Petronas?

Looks like Kroon oil made a mistake in their catalogue??? Will contact them personally...
The oil they use for USA/Canada is not a hydraulic type??

Beste Andre,

Bedankt voor uw feedback. In eerste instantie inderdaad een opmerkelijk verschil in advies. Als ik de EU adviezen vergelijk met de USA adviezen dan zie ik inderdaad een verschil in voorgeschreven specificaties. Voor de USA modellen adviseert Alfa een Mopar PN 68092630AA specificatie voor de hydrauliek van de bakbediening. Deze specificatie is inderdaad een API GL4 SAE 75W transmissieolie. Voor de EU modellen adviseert Alfa een olie volgens Fiat 9.55550-SA1 specificatie, een automotive hydraulische olie voor o.a. cabrio kap bediening, hydraulische bediening versnellingsbak etc. Ik ga er vanuit dat u een EU model heeft en ons advies is om inderdaad de SP Fluid 3023 te gebruiken voor deze toepassing. Wij zullen onze dataleverancier navragen het OEM advies voor de USA versie te controleren en indien nodig aan te passen. Wij vertrouwen erop u hiermee voldoende geïnformeerd te hebben.

Google Translate to English is interesting. So the spec difference appears to be from Alfa, or from their supplier.

Thanks for your feedback. In the first instance indeed a remarkable difference in advice. When I compare the EU advice with the USA advice, I indeed see a difference in prescribed specifications. For the USA models, Alfa recommends a Mopar PN 68092630AA specification for bucket control hydraulics. Indeed, this specification is an API GL4 SAE 75W transmission oil. For the EU models Alfa recommends an oil according to Fiat 9.55550-SA1 specification, an automotive hydraulic oil for convertible top control, hydraulic gearbox control etc. I assume that you have an EU model and our advice is indeed to use the SP Fluid 3023 to be used for this application. We will ask our data supplier to check the OEM advice for the USA version and adjust it if necessary. We trust to have informed you sufficiently

One of the specs is the actual transmission oil, perhaps?

Think they made a fault for the hydraulics
Best thing is to stay with the oem oils just to be sure...

Thanks for the translation btw

The shop manual I have for my 2017 is a bit different process than the 4C Cloud version (2015?) above. A carefully placed light does help, my level was at or a bit above MIN after opening the door/triggering the pump/pressurizing the system so once it is depressurized (I need AlfaOBD) it should fall in between MIN/MAX as desired and where the visible line is on the 4C Cloud process labeled as MAX.
And I can see why shaking the car is required to establish where the fluid level really is, these reservoirs get stained on the inside and may look to be higher than actual.

Yes, Mopar PN 68092630AA is the actual transmission gearbox fluid, the hydraulic selector fluid is Mopar P/N 68092638AB

I just took a picture this morning showing the level. Sorry but I still can't figure out what the MIN mark is
