Hi - 3.3l built 10/97. 103K miles. 'Service Engine Soon' came on. Diagnosis codes P0731 (incorrect ratio for 1st gear); P1784 (L R Pressure Sense Circuit) and P1790 (TP Circuit Malfunction or Fault Immediately after shift). Car drove normally and light went off on its own next day. A service bulletin was issues in 2/98 stating software update avail thru Chrysler to correct these errors. Anyone have similar experiences and what was the outcome?
