Consumer Description

No check engine light come on until continued driving over 15-20 miles. Transmission slams into second gear when taking off or when stopping it may or may not downshift into first causing safety issues when in traffic. Possible electrical error or clutch inside transmission. On this model it is a sealed transmission so no way of identifying if metal shavings come out with a transmission flush. The issue only happens when vehicle is at temperature, if under and still cool drives perfect but as soon as it hits the temperature of 210 it slams very ugly.
