Have you had the trans serviced recently? If you don't know when the last trans service was I would get the fluid and filter changed as a minimum, doesn't cost that much and contamination is often the cause of many trans problems.
It was done about 15 000 miles ago, I tried putting a ball bearing into the vacuum solenoid line, this did not help at all. I have an appointment to get the fluid / filter changed in couple of days. I was really hoping someone had experienced this problem before.
I don;t know if there is an electronic diagnostic method for this transmission engine combination.
Thank you for your interest.
