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.

Something inside the transmission. TCC solenoid/valve could be a cause. Have the codes checked, even if the check engine light isn't on.

Well, the first thing one should check is the transmission fluid level. Add Dexron ATF to the transmission until full when the vehicle is at normal operating temperature after 30 or 40 minutes of driving.

Secondly, if the car's transmission hasn't been flushed and filled in 30,000 mi. it's recommended that you do so as normal maintenance. This service typically costs about $100 or so.

If the car only runs forward but not reverse, a solenoid may be plugged up with clutch dust, or it's shorted out and needs to be replaced. However, tearing down a transmission on a 2001 Cadillac Seville is rather expensive, in the thousands of dollars.

One might consider getting a good used transmission that has a guarantee on it and have it installed, or have the one in it rebuilt.

Good luck on this repair.

The 1998-2004 Cadillac Seville SLS use the 4.6 L LD8 Northstar V8 motor. As long as your replacement motor is the same as your original motor then it will fit perfectly

i have a 1994 cadillac seville sls and it wont shift out of 2nd gear i have replaced the shift silenoid "B" and the vss and it still wont shift and the pcm is still good. What else could it be?

The engine control codes need to be known to go further The codes can be retrieved at most auto parts stores as they can sell you the parts recommended to fix the cat they usually don't charge to retrieve the codes and then the parts lookup computer can make some recomendations on the repairs needed. The transmission codes might not be retrieved this way and this is only giong to give you an idea of whats wrong and not a for sure. Following though on engine control codes is best left to a pro and the parts guy can probly tell you a shop the fixes cadillacs regully and buys the kind of parts that yours might end up needing

The selector switch at the transmission!

check trans cooler lines

Yes, unfortunately it sounds like you have a blown head gasket. You can check your oil dipstick to see if there is any water in the oil and also check your coolant to see if there is any oil in the coolant. If so then you have a blown head gasket. The problem can only be resolved by having the heads machined and replacing the gaskets.
