CUSTOMER LETTER - UNDER CERTAIN DRIVING CONDITIONS, THE SOFTWARE IN THE PCM CAUSES A LOW PRESSURE PROBLEM IN THE CVT. THIS MAY ALLOW THE BELT IN THE CVT TO SLIP. IF THE BELT SLIPS, YOU MAY SEE A SURGE IN RPM WHEN DRIVING AT HIGHWAY SPEEDS. IF THE BELT SLIPS LONG ENOUGH, THE TRANSMISSION WILL BE DAMAGED, AND DTC P1890 WILL SET.
