Auto Parts: dodge transmission, dodge duster, solenoid

Question
I have a 1995 dodge duster 3.0 the transmission pops into 2nd gear when the car gets warm about 2 miles what solenoid do you think needs changed or do you think its the computer

Answer
    If this is an automatic transmission we're talking about, then you have what is known as Chrysler transmission syndrome.  Chrysler's FWD transmissions have never been very durable.  Odds are you are going to find yourself with no gears fairly soon.  I would start looking for a good used unit and someone who will do the swap at a reasonable price.
