206 auto problem

[Woodyzapp]

Hi I have a Peugeot 206 1.4 lx automatic on a 99t plate. On the dash the snow and the sport light are flashing and the car appears to be stuck in 2nd or 3rd gear, limp mode I guess.

Took the car to local garage were the put it on a diagnostic machine this is what it came up with:

Slipping (clutch brakes). Intermittent fault

Sequence solenoid valve 1 output fault open circuit. Permanent fault

The guy then tried to see if he could reset it and the machine now says:

Accelerator pedal programming not learnt. Permanent fault

He checked the transmission fluid and says that's ok.

Just wondering if anybody out there has any idea as to what the problem might me and what I could try to fix it. Any help would be greatly appreciated .

Thanks in advance
