355 355 F1 Gearbox warning light is on, Slow Down is Blinking

Hello , Im Michael from Berlin,
first I would like to apologize for my bad english.
FChat is the most important Ferrari forum for me, because of my bad english Ím a reader only, until now


I have a big problem with my 355 GTS F1

After changing the clutch flange and Bearing Ím desperate.
At first it starts normal, so I bleed the the system (without sd2),
than I start the self calibration (pis, io and octopus; d41 wsm).
At the end of the io calibration the slow down light begins to blinking and the gearbox warning light going on.

Now, if I put the key in pos.II, the Gearbox light is on and it BEEP (4 Times).
I can only shift in 1, 2 and R……if I start the Motor I only shift in 1 and 2.

I believe to test everything, but I dońt find the solution.

- Pressure Sensor is working
- Speedo Sensor is working
- Octopus calibration is okay and confirmed with one beep
- Relais and Fuses all okay
- vescovinis are exchanged with the duo cat ecu from ScudIng Swiss

Headaches give me the slow down blinking if I the motor is running (combined with gearbox warning light).
Im sure the slow down blinking in combined with the gearbox warning light are related errors.


Thanks a lot of your help
Kind regards from Germany

Michael
