1994 Buick Roadmaster • V8 2WD Automatic • 95,000 miles

Our 1994 Buick Roadmaster is being serviced for rough shifting. The mechanics stated that they had changed the computer. They also said that they must now bring the car to a dealer shop to reset the computer because their equipment only goes back to 1995 Buick Roadmasters and they must have a dealer reset the computer. This does not agree with all that I have read regarding the computer reset. The VIN is: 1G4BN52P8RR413337. Please advise me accordingly.

The computer does need to be reset or reprogrammed. I can't tell you about their equipment, but honestly, things change so fast, everything becomes out dated.
