Q: Am I being scammed?

I hesitate to say anyone is pulling a scam, but it does sound like you’ve been through a lot. Lets take things one at a time. To start with, it’s not uncommon for transmissions to fail after a fluid service. If you are in the habit of servicing your transmission every 60 thousand miles, then a fluid change is a good idea. But if you let the transmission go 160 K without a service, changing the fluid can cause built up deposits to break loose and they can clog up the works. If you have a car with high mileage and no transmission problems, it’s best to say "No, thanks," to a recommendation for service. It’s hard for me to say from here what might be wrong, with respect to the vibrations you are experiencing, but don’t just let it go, if you think that something is not right, it will probably get worse. As for the oil leaks and overheating: whenever you do major work on a high mileage car, you shift things around and put stress on all the rubber parts by taking them loose and reinstalling them. Pieces that were in marginal condition will fail and cause you a series of problems. It will look like the mechanic screwed up, but it may be more like he opened up Pandora’s box and the problems that were in there waiting to come out, did. I like to try to head these problems off by replacing all those worn rubber parts, but that drives up the repair bill and makes it look like I’m trying to scam you. That said: if you think you’re not getting what you pay for from your guy, you should contact Your Mechanic. They can send a technician to your home or office to check out your Honda and advise you as to your next steps
