Thanks for a great forum and thread.
I jumpered the diag connector on my 90 Accord and the "S" light gave me the following codes.
7 short blinks
8 short blinks
When the light begins flashing, I lose 1st and 4th gear. If I turn the care off and back on, the light will reset, but once it shifts into 2nd, the "S" light starts flashing and no more 1st and 4th.
Can anyone shed some light on these codes and some possible causes?
