2005 Cadillac CTS Question: How to check transmission fluid level?Better to flush or change(filter)&fluid?
if your car has a lot of miles on it and the tranny fluid hasnt been changed before it would be best just to leave it alone just make sure the fluid is topped up - goodguy
i rec you have it done by a pro,these can be slightly diff to deal with. there are alot of places that do it for a very fair price - globalhelper
