So I just bought inherited another 4 runner from my uncle. From what he can tell he has no knowledge that the tranmission had ever been serviced in the 200,000 miles he has owned the vehicle. He took the vehicle into the shop to have it serviced before he gave it to me and had the transmission fluid checked. It came back dark brown/black in color and had no particles floating in it so he had his mechanic the flush the transmission and change the fluid. My question is has anybody ever heard of 4 gen 4 -runners having transmission failure after the scenario described above or is the transmission failure on high millage cars just kind of myth ?
