So I have had this truck 1 yr now and recently the tranny feels like it is staring to hit gears harder. Especially when slowing to a red light but then accelerating as it turns green, it down shifts then feels like it gets confused and finally hits up a gear. I have 69K miles and figure the tranny fluid and filter needs changing. Any thoughts?
