Hi i have a 93 850glt yesterday the orange arrow light in the dash started to flash. I checked the fluid and it was very muddy looking so i drained off about 3 litres and refilled it with new oil . I then took it for a test drive after about 5kms the orange light started flashing and i just managed to get home. This morning i started the car and the orange light came on again i then left it for about an hour and when i went back to it and started it there was no light on and the car would move back and forwards but after 2-3 minutes it would'nt move . I checked the on-board diagnostics which gave me the code 3-2-3. Which say's in the manual Lock-up slips or not engaged. Hope someone can help thanks.
