1 Radiator Hose problem of the 2007 Nissan Frontier

Failure Date: 07/13/2019

While driving on the highway on 7/13/2019 I felt my truck jerking/tugging which has never happened before. On 7/14/2019 the 'service engine' light came on and the jerking was more noticeable, I made an appointment with the local Nissan dealer for service on 7/16/2019 and I was told that there is coolant mixed in with the transmission and the tcm eventually fried since it is housed inside the transmission, apparently the transmission cooling hoses route to the radiator and the only remedy is to replace the transmission and the radiator. I searched online and found that I am not the only one that this has happened to. The problem.
