I have owned a 93 850 for at least 10 yrs. A couple years ago I posted help for PNP and then transmission solenoid. Last year I finally got around replacing the S2 solenoid and things were looking up!!
HOWEVER....the newest problem is that the car has started to surge in gear at stop. The idle severely drops and the car must be placed in N or P. Once the red light changes, I have to place the trans back in D and after a sluggish start, it runs fine. Until.......another red light!!
This appears to be the torque conv. not slipping properly? I have check the fluid and all appear OK. No light on the dash but I plan to run the diagnostics on trans (front fender). Has anyone experineced this type problem? What was the outcome? I considered changing/flushing the trans?
Is there some type of idle kick-up that may cause this problem?
