2018 Raptor engine problems after replacement

[Nb120]

I have a 2018 Gen 2 with 91k miles, i just got it back from getting its third engine after the second one grenaded itself, and as i was driving on the highway in traffic at around 35mph it was in 7th and was jolting hard and it seemed like it didn’t want to downshift into a lower gear. and at idle it rattles hard and then raises the rpm’s and then it’s fine after that, it also takes a while for it to gain power even when the turbo is making boost.

May I ask the circumstances for each of the engine replacements? Sorry to hear!

first motor went out because of hard driving and was towing way over its max. The second one blew randomly didn’t show any signs of it being hurt, i’m thinking that it’s probably from towing a lot that hurt the trans but even before the 3rd motor the transmission has always been fine

Sounds like you’re using a performance 1/2 ton truck as a 3/4 ton diesel work truck & this is the end result, lots of people do towing/hauling w/ these w/o issue…..how much weight are we talking about & how often?

Were any of the engine replacements under warranty? I imagine yes or otherwise you’d have been much better off cutting ties w/ it & buying another?

I’d consider using some transmission fix fluid see if it helps or if tranny shifts better once warmed up & trade that thing in asap
