Another 3rd Gen torque converter issue?

there are many tunes available for your truck year/engine combo if that floats your boat. the stock tune is geared towards maximum fuel efficiency (does a great job of it too) but it can effect driveability depending on your driving style.

 

update?

 

what about ones that are brand new?(my 2022 has done it since day 1 ,worse with ac on?)

 

My 2023 has done it since new and they finally replaced the torque converter. It is much better now but it's still does not feel smooth, not like a new $40,000 truck should feel.

 

They are putting a new tranny in mine after i finally brought it to them ,mine was feeling just like what OP was describing except mine was doing it since brand new and ive kept it stock ....was getting ready to pull the trigger on an OTT tune but i read my tuners disclaimer that basically said if you have TC shudder the tune will only make it worse .Whatever my problem is (they didnt specify )one test drive (without me )and they immediately said new tranny.No runaround like OP has been given( feel sorry for you bro ,and i was expecting the same thing thats why i hesitated so long to take it in)

 

did you ever get a tune and did it shudder anymore?
