2012 Raptor, 92k miles and 100% stock. Bought the truck 3k miles ago, and just noticed this starting:
When sitting at a red light, if you ease partly off the brake to roll forward (still a little resistance on the brakes) the truck shudders, like an up and down motion in the rear end as it eases forward. It's a very rapid shudder.
The same occurs if you are sitting at a light with a slight uphill incline.... if you lift 100% OFF the brake and let it roll forward. No other shudders on acceleration. It's just when easing forward at say 1mph.
The truck has 92k, never had trans fluid changed
Any thoughts?
