   Discovered leaking fluid on 9/12/2026. Scheduled service with local Acura dealer on 9/15/2026 and found that the leak is AFT from unserviceable seal between the transmission and transfer case. The recommended repair from dealer is to replace both transmission and transfer case for $15,000. This is a significant issue for a vehicle that had been well maintained.

   The car was being driven as normal and while at a stop light the car shut off and alerted the driver with a transmission error code. The car would not start for about 30 mins after the incident. When we took it to be looked at by the dealership we were told that it was related to code P07E4. The dealership reset the system and the code and returned the car back to me. They stated that if this happened again they would need to replace the transmission. My concern is that this…

   While driving home on a Sunday afternoon, out of nowhere, a very loud pop sound happened followed by grinding. We were so worried that my husband pulled over thinking we had done major damage to the car somehow. Visual inspection under the car yielded nothing leaving us puzzled. No warning lights came on before, during, or after. We had it taken to the Acura dealership in Fairfield, Ohio. The car was still within warranty at this time, and they found nothing nor could they…

   Factory seal allows water to seep into the internal coupling cavity. The water mixes with the factory grease, creating a rusty, muddy brown fluid that eventually washed out and leaks from the casing. Over time, this moisture causes the interfacing splines between the transmission and the transfer case to strip and shear off completely.

   At 75,000 miles I noticed that the vehicle was losing fluids on the bottom. The fluid color was a reddish color. I took it into Acura for a diagnosis and I was told that the seal between the drivetrain and transmission has worn and is causing all of the fluids to be leaked out of the car. They told me it would be $10,000 to replace the drivetrain and transmission because the a repair cannot be made.
