There is a problem with the transmission.

Count the blinks from the Transmission Control Unit's LED, located under
the forward part of the passenger's carpet. Pull the carpet back, turn the
ignition to "II" and read the blinks.

The PGM-FI ECU also has an LED, which may also be blinking a code, so count
those too, if needed. The ECU is next to the TCM.

Any unusual symptoms? Strange shifting behavior?
