2000V70SE Light flash & temp loss dash speedometer
Sudden loss of speedometer with flashing dash lights. Most soon go off but the "low gear" light continues to flash. Stopped car. Turned off. Restart & car very slow to first gear, but proceeds.
After 15 minutes, dashboard lighting returns, including speedometer.
ATF fluid at appropriate level and color looks good. Has 150k miles.
Thoughts?
