2002 Saturn SC1 3-Door Coupe - Mechanic replaced transmission, then said computer had made the transmission bad, needs replacement. Is that logical? Transmission coded "gear ratio incorrect" and was replaced. Mechanic said the car's computer was bad and that it had made the first transmission go bad. Said computer needs to be replaced and the cost is $500.00 to buy part and $65.00 per hour for labor. Is this a reasonable repair? I can't find any reference online to a computer in my car.

The gear ratio incorrect could be coming from the clutch packs slipping-Get out of there and get a 2nd opinion

Just to add to this one I have never heard of a bad computer damaging those transmissions. Usually when you get a incorrect gear ratio code its caused by a pressure issue which is a bad pressure regulator in the valve body. You want to blow the guys mind that replaced the transmission. Ask him what the exact codes were and how he diagnosed step by step it need another transmission. Please let me know what he says most likely he will say because it had the gear ratio code. Which is a bunch of nonsense. Also ask him how he knows the computer made the transmission go bad more fun there. When I worked at saturn I used to get calls all the time feom transmission shops that couldnt fix the transmission.I even had a major transmission shop chain like the biggest one out there. The transmission was shifting hard in every gear they rebuilt the transmission and it was still ahifting hard. They brought it to saturn I looked at it 20 mins later found it need a line pressure control solenoid not a rebuild. More times then not when you have a gear ratio code they want to tear it down and rebuild it or replace it. Without ever doing a high low pressure test and step pressure test followed by air checking the clutches.I know those transmissions well.
