automaic transmission oil radiator (AL4 overheating)

hi all,

I'm sorry for my bad english first.

I've c3 2003 1.4i bva petrol automatic..

* snow and sport light was flashing..
* Sometimes, Although i was not going to press the gas.
* When the gear 3rd gear to 4th gear, was left undecided. It suddenly slows down. So, 5-10 seconds sport and snow light flashing.. And then go on normally.

I had some problem with automatic transmission.

automatic transmission was repaired. Some parts changed inside. changed solenoid valves.

Now..
In heavy traffic, stop-and-go,(stop and go, stop and go, for 10-15 and over minutes) the gear can remain undecided in the transition from 3 to 4. It suddenly slows down. So, 5-10 seconds sport and snow light flashing.. And then go on normally.

i have lexia..

automatic transmission oil temperature seems to over 100 degrees in heavy traffic.. Other times about 90 degrees..

I wonder where the transmission fluid is cooled ?
There are two radiators in my car .. What are these?

Because of stone smashed the shutters side ..

i want to change radiator.. so, are problems (automatic transmission problems..) solved

thank you all.

Number 5, its a transmission oil to water (engine coolant) cooler.


The water is cooled by this radiator:

If you fix this first, you may solve your other problem? Its worth a try

Special coolant for the Citroen C3

i have lexia..

What faults does lexia show for your automatic gearbox - sport and snow flashing?

Thanks a lot

So, I want to reduce the temperature of transmisson oil.. how do?

i see "slip clutch" on Lexia...

Sounds like one of the clutches is slipping.

Repair the slipping clutch would be my suggestion. Slipping clutch creates friction which makes heat, which heats the oil....

there are two radiators..

one of them, The water is cooled by this radiator.. (first or second?)
the other one, what does ? I understood the part No. 5.
its a transmission oil to water (engine coolant) cooler

How does circulate oil,
where to go Is it possible, for c3 thanks all again.

for the climate control?

It goes like this

I don't know what this is cooling? But I don't understand how it can repair your slipping clutch (as lexia says you have).

i know exactly now..

Thank you all again..

now,
oil temperature 119 C degree.. i think so high ?

I don't know what the temperature should be, but the fault you show in your lexia screen captures in not a temperature fault. If there was a temperature fault, I would expect lexia to log a fault for it.

Lexia has detected faults with the clutch/brake parts.
If you clear the code does it come back?

Lexia thinks you have a problem with a slipping clutch.
