2002 Cadillac Seville SLS Questions & Answers
I ment a 2002 Cadillac sevile SLS won't go into reverse??
If the vehicle will not go into reverse, you are having a transmission issue. Check transmission fluid level and condition. If fluid level is correct but fluid is burnt or watery, immediately have fluid and filter changed but don't expect a miracle... it may or may not fix the issue.
You may be looking at the need for a transmission rebuild.
How can I tell if I have a faulty wheel speed sensor on 2002 Cadillac Seville SLS
One possible cause is that these systems remember values from the last time the vehicle was started. Sounds like sitting for a long time is caused unacceptable differences between current and last readings. This is possibly because of a vehicle attitude change, often due to a low tire pressure. Modern low profile tires are very sensitive to pressure changes - pressures tend to drastically change with changing ambient temperature and will deflate over time.
Also try starting the vehicle more frequently - that is needed to keep the drive train and electronic systems in good working order.
