Question
QUESTION: The O/D off light is now on after having a smog test and having a hose replaced. What to do to get it to turn off. Brake light is on  but will turn off for a few minutes after I have stepped on the brake hard. Then it comes on again.

ANSWER: Hello, have you checked the brake fluid? Check the electrical connector on the master cylinder?

---------- FOLLOW-UP ----------

QUESTION: Brake fluid is fine. Brake light jas been on for at least 3 months.
OD off light came on after a new AIR intake Tube Resonator was replaced to get smog certification.  Today one time when I stepped on the brake today, brake light stayed off for almost 30 minutes, (happens randomly),sometimes it just a few minutes, to several minutes. Maybe a selenoid?

Answer
It could be a problem with the fluid level switch on the master cylinder, remove the electrical connector and see if the light stays off, if not place a jumper wire between the two terminals on the wire connector if the light stays off replace the level sensor, the overdrive will not work as long as the warning light is on.
