Citroen C3 Owners

Hi everyone,

what a nice forum and thank you for all the good posts . I am facing a bit of an issue with automatic gearbox and after some suggestion/pointers.

I have C3 SX 2007 1.6 (petrol) Automatic, the gear box shifts are very smooth when car is started, after some drive when i approach a round about or approaching a slow moving traffic and breaking then transmission changes gear down as you expect it to be however, now when i press accelerator i can see gear box is bit hesitant & then with a Jerk it gets into gear and start to drive okay.

I am thinking it needs ATF oil change , There are no fault or snowflake icon on the dashboard. Has any one else faced this ? if this more than ATF oil issue ?

Thanks in advance for reading !!

Wow! A plethora of AL4 faults.
Forgive me if I cut and past from another post.
The results from changing the gearbox oil seem to vary. It works for some and not for others. Just because it works for them doesn't mean it will work for you and vice versa. I believe either way it's not a permanent solution.
It seems 70% of the time the fault is the pressure regulator or torque converter lock up electro valves.
30% of the time its a worn out auto gearbox. If the gearbox is worn out a rebuild is typically uneconomical. However, it tends to be the brake bands and friction surfaces that ware out and this causes the gearbox gears to slip and you get "rubbery" gear changes.

JAGPURR has a post on how to change the electro valves here:
