Hi, today I was driving the car and for no reason is really strugled on hills, it tried to sort itself out and the gearbox was jumping from gear to gear trying to get drive. I pulled over and when I pressed the accelerator it was wery flat on the low revs, almost like it was "missing". I started driving again and the same, really struggled and almost died on a hill. I stopped again but once I set off the "trans fail prog" warning came on the dash. I limped home and she's on the drive, any ideas?, by the way I hadn't just filled her up, she was on the same fuel for the part week with no probs, even that morning I went out and she was fine.
