Honda replaced my converter and now if I drive over 3 miles distance then D flashes. They said it was the torque converter and kept replacing it. Took it to a trans shop and they said the clutch solenoid was not mounted correctly. Was fine for 300 miles. Took it back to shop, light will not blink. Drove it 40 miles home and now it blinks.
I just have no idea what to do next if shop can't figure it out. Fluid has been drained and filled 3 times. 92,000 miles on transmission.
