Newest TCM flash. Don't get it if you're not having issues
We all know all the issues we have been having with shudder.
If you don't have issues DO NOT get this flash. Jeep changed the entire shift strategy to avoid shudder, in doing this they have killed fuel economy on anything other than flat ground.
I data logged to confirm my suspicion. If you have the cruise on in a hilly spot it's the most noticeable. The jeep will not allow more than 20% pulse width below 2000 rpm in gears 5-8 (that I have confirmed). so now instead of using tq to help up hills it bogs down and down shifts killing economy.
To say I am pissed that Jeep is "detuning" our vehicles to avoid design flaw is an understatement.
