Q: Transmission problems

A diagnostic is only meaningful if there is a specific identification of a part or parts that have failed, are worn out, defective or the like. The bearings in the differential that you refer to are not visible for inspection, even if the axles are removed from the vehicle, which I presume didn’t happen because removal of both axles is involved. Thus, their mention of bearing failure is nothing but a guess. One way to inject some rationality into something like this is "get it in writing". In other words, if a mechanic cares to offer you a diagnostic get the result in writing so that you can then evaluate what is being claimed. You’re dealing with a very technical subject and whatever they "say" is going to be hard to parse and pin down unless it is in writing and you can then, at your leisure, see if it makes any sense. One thing of concern is the relatively low mileage on the vehicle. One-hundred thirty-eight thousand (138,000) miles on a Honda transmission is not a lot and if you are the original owner and the car was not abused, I would not expect the transmission to be worn out. So, the next person who says there’s a problem with the transmission, ask them to write down the specific Diagnostic. If they refuse or even balk at the request, that means there is either nothing wrong with the transmission or they fundamentally lack interest in your problem, of course, in either case your task is to simply find somebody else who can help you. If you are detecting noise from the transmission, do get it investigated. Obviously, a certified mechanic, dispatched by YourMechanic can come right to your location if you request a noise diagnostic and that responding certified mechanic will get this resolved for you.
