Ok so I found something else wrong with the 02' ram quad cab that I just bought used two months ago. I've noticed that sometimes when the engine is cold, when i put the Trany in reverse it takes a few, maybe 3 or 4 seconds until it seems to actually go in reverse. No other problems, it shifts great, no noise from gears and doesn't slip. I drained the Trany, changed filter and oil. Same problem. It's an 02' with the 4.7 automatic.
