01 civic 100,000 km Check engine light came on last week, so the dealer charge $90 to check the codes,































codes are p0700, p0131, p0740































said transmisson , rear main seal , and the o2 sensor are gone, all at a nice total of $4000 + tax































the tranmisson fluid was changed last year































Any recomendadtions , the car runs perfectly fine, and there is no light on right now. Not really sure how i can have a transmisson problem if the car runs perfectly fine

You need to have this evaluated by a trustworthy mechanic. The first tip off that you were at a bad place was the fact they charged you $90 to read the codes. For $90 you can BUY the code reader itself! Don'y ever pay more than $30 for diagnostics. Get a second opinion. Or a third. And if it ain't broke, don't fix it.
