You must get transmission service done. it will replace the pilot bush in your transmission your car have a 5 speed tiptronic transmission it's need to get transmission service done at every 65000km otherwise you will get problem. seems to be leaking from pilot bush.

Mine is having the same problem. What was wrong with yours? I hope it is nothing major.

take the car to dealership and get them to cancel the fault memory of the engine control unit. Then if the warning light comes back on you will need a full diagnosis check to establish what is causing thefault.

Why not take mit back to the place that repaired it and ask them to fix it properly?

I have always had a place in my heart for the Olds Cutlass. I own a '90 Olds Cutlass Calais--WITH the fuse box COVER. I went out to the car and removed the cover and have it next to me so that I can type the EXACT fuse order as they appear on the inside cover.There are 2 col. When I've finished the l/h side, I'll make a line to indicate the start of the r/h side. I will also put the Circuit on the left & fuse on the right. If you are ready, HERE WE GO:

Check your ABS sensors. One is likely bad.
