After watching many video's on YouTube regarding how to tune these TCM's to make the transmission last longer i decided to call a local tuner to see if he thought tuning the TCM(only) for longevity was a good idea? I said to this tuner i wanted him to make the changes below. He said that this was a bad idea in a nutshell which basically contradicted everything i have been reading and watching.
Is this tuner "full of it"? or will making these changes help my trans last?
