Well I put my range and delete on while driving around today and it didn't do anything to stop the shudder at 25mph...i did however switch into manual mode and shifted into 2nd gear (No shudder) 3rd gear(No shudder) 4th gear and up had the shudder
Sorry should be specified, it's a 6 speed, I have a range afm module so I can try and see if that makes a difference but I'm pretty sure when I was using it before it made no difference
Hey guys I have the rumble strip affect when decelerating around 25 mph. If I throw the truck in neutral and slow down the rumble doesn't happen...yo8 think torque converter??
