It is not possible to actually determine that such an error is actually a transmission error. Unfortunately, with the way the error systems are linked, when one thing goes wrong, it will usually set the rest of the errors off. If you can bring it to the dealer immediately when the error is showing (try not to power down the vehicle, as that can sometimes make the problem go away), they can see it (you will learn that with Honda/Acura, you have to show them each problem) and possibly go about diagnosing it.Mine isn't being replaced as of yet, but I am getting a transmission error from the computer on my 2017 MDX awd tech. Anyone else have this issue? I get a slew of computer errors: Parking brake error, emission error, BLind spot monitoring error, and transimission error. I am hoping this is only a computer glitch and just needs to be reset or loaded. The cars transmission and acceleration feel fine otherwise. This has happened twice so it is a little concerning. I only have 435 miles. I am not a bot! I am leasing this car but it isnt what I had in mind! I would have bought an Audi or VW if I wanted to visit the dealership all the time!
