I'm new to the forum having recently purchased a 2009 Fortwo Passion with 86,000 miles on it. I have only had it 3 weeks and 500 miles. It has run perfectly until yesterday (Even with the stupid transmission). Yesterday, running it in the automatic mode, as it was shifting through the gears it went from 4th to 5th as normal. Then it down shifted to 4th gear. After a few seconds it shifted back to 5th, then down to 4th. It kept doing this until I pulled the shift lever into the manual position. It ran like normal when using the paddle shifter and 4th and 5th gears worked great. Today I disconnected the battery, reconnected the battery, started the motor and let the computer reset everything. I just finished driving it in automatic mode and it is doing the same thing, shifting back and forth between 4th & 5th gears. I could use a little help from anyone. The nearest Smart Car dealer is in St. Louis and I am 180 miles south of there.
