I dropped my car off at the dealer to fix my fuel gage. He offered the 30,000 mile service to me. The car only has 26000 miles so I indicated that I would wait. What I really want to know is if that service is really worth it. He indicated that they open the transmission and change the fluids. I have heard many mechanics who advise not to fool with the transmission if it is not given a problem. The service mananger also indicated all the stuff that is done to the car. many i do not need because I have done them recently. ie tire balance, blackwing filter etc. Transmission and coolant I have not done. Any advise would be helpful. He indicated that automatic transmission and coolant change would be 270.00 dollars. Thanks
