Car stays in third gear only.

So just recently I went ahead and changed the oil in my car. Started
it up, everything was running fine. Car sounded good, ran fine, and
when I parked it in the driveway, it seemed perfect. Later that day I
went to start the car and it started making all of these clicking
noises, one by the underside of the shifter and another on the left
side of the dash. I assume these to be connected with the not being
able to take your key out unless its in park. I have also been having
problems with the little park light not coming on when I put the car
in park.
It really only does this when its cold.
Any advice on what needs to be fixed?

 

=============================================

Best if you tell us the make, model, year and mileage of the 'car' and
then we can tell you how to fix it.

If you want to look for yourself, you'll find some TSB's that apply to
your mystery vehicle here: http://www.tegger.com/hondafaq/tsb/

You also need to clean and tighten your battery terminals, and possibly
the battery ground connection.

I don’t think this is the perfect fix but it’s worth a try. I have had
a similar problem with ours, the buzzer was going off & the car only
wanted to run in od. I disconnected the battery for a couple of hours
to let the computer reset itself. I reconnected it & all was fine.
