Welcome Tink to the forums. You have found a great place for info, how to, and advice on Smart issues.
I also had shifting problems, and used these forums, and also the Evilution site to get everything sorted out.
Sounds to me like its either the shift actuator, or the shift motors. My 09 passion, has 84K miles, and was throwing
codes, occasionally would not go into gear, and one time locked up completely. So, use this forum, try all the
techniques, and you should end up with reliable, smooth and proper shifts.
If you have not already, get a code reader... that will help to identify the problem. Try to re-learn the tranny, very
easy to do, and will usually get you by as a temporary fix. Removing/Inspecting/Cleaning/Reinstalling the shift
actuator is not that hard. The Transmission shift motors is a bit more difficult, as you need to remove the air box
to gain access. If you get to that point... you may as well change the tranny fluid while the motors are removed.
Instead of reinstalling the air box, get a cold air intake tube, much easier to deal with, and I think the car runs
a little better with it.
Where are you located, how many miles on the car, are you mechanically inclined? Maybe I should have asked
these questions first?????
If the car was actually in manual it would do just what you are describing. So being new to Smarts the first question I have for you is when you purchased the car is that what the previous owner reported was a problem with the car? Because you seem to be indicating that the car is shifting up and down in manual mode. again being new to Smarts it sounds like you may not know how to get car back out of manual mode. Since I don't believe you can start your Smart with the floor shifter in the manual side position, do you have shift paddles on the steering wheel? My daughters all called me the first time they drove my Smart to to ask how to get car out of manual after hitting the paddle shift accidentally when turning.
So turn the car off and take out the key out. If you can do that the shifter is in the auto position where it should be. Then start up car and move lever to "D" and just foot on gas and drive car with out touching paddles. see if it will shift.
Also ask previous owner about it if it was not part of a problem they had with the car.
From manual 2 ways get back to automatic hold the up shift paddle in until the gear indicator turns to "D" , or moving the floor shift lever to the left then back to the right the right will get you back to automatic mode.
