Re: Is ecm tuning worth it?
Kind of.
TM only comes into play during shifts. It works by closing throttle, pulling timing or a combination of both to prolong trans life.
It's become much more prevalent as HP and vehicle weight has gone up over the last 5-6 years.
Killing it in a heavy vehicle with a lot of HP will have a significant negative impact on transmission life and is NOT a good idea.
