Having problems with your 1997 Buick Century ?
Transmoissin when hot wont shift to overdrive
You could try having the fluid changed but beware, if it hasn't been changed in the last 100k miles or so the fresh detergent in the trans fluid can sometimes clean too well and leave you needing a new transmission. If you know it's been over 100k without a fluid change my suggestion would be to keep nursing the trans along and start saving money for a new transmission or a new car.
