Looks like a new recall incoming for the HO engine - MOD EDIT: NOT confirmed for HO - this is Chassis Cab SO trucks recall W57

The C&C trucks do not run the HO.

The CC have an Aisin mated, I thought they were detuned HO motors 2019+?

[ETA] OK, so I checked the specs on the CC engine and they have the same compression ratio as the SO pickup, which would make them an SO motor, so @1HasBeen is correct.

"Warmup protection" = (more) reduced power modes when cold.

If you look closer, at the correct recall documents for W57, it's clear this is for DD and DP trucks, (DD) 3500 Cab and Chassis and (DP) 4500/5500 Cab and Chassis trucks.

Welcome to the club kung pow. Just wanted to let you know that someone had already posted a thread in relation to this topic if you don't see allot of activity on this one. Great heads up though. The various articles aren't quite clear if its for just cc or all ho . Not much consistency in info on the articles
 
@KungPowMinchow Welcome to HDRams! Please feel free to post a pic of your truck and introduce yourself in the new member forum.


All, if the thread looks weird, I keep having to merge multiple threads/posts into this one. Shame HDRams doesn't have a search function. ;)

Reading the attached documents, this is for C&C trucks, not pickups, and not HO. The C&C Cummins tune is different than pickups.

He's right. Read the attachments.

It's for Cab & chassis trucks, SO engine (typo in docs?), pickups not affected (yet?) by this recall. It's a software tune fix for the "Inadequate warmup protection"

Well Guess I have all the proof I'll need down the road to Make Dodge replace my engine fee of charge. There is no way they can say damage wasn't caused early on, due to their inadequate PTM tune...shorting engine life. ~~~Kracker
