Slow speed shudder in eco mode 2018 SRT

opticjimg · Mar 18, 2022

2018 Durango Morpar 18 edition
Hi had a shudder under light acceleration only in eco mode.
It is the DTCM, Drive train Control Module . It was reprogramed / flashed to current part number 68250125AG
Shudder got and drives much smoother, just posted in case anyone else has this problem

could it simply be the engine switching in and out of 4 cylinder mode..

no, the the flash of the DTCM fixed the whole problem drives much better now

Did it do that just when going into 4cyl mode or continually when in 4cyl mode?

continually, been 2 days and nothing

At 25k miles, my 2018 just started doing that when 4cyl mode kicks in, but not continually. Feels like a downshift or play in the drive train. Doesn't always do it, could be related to grade.
