[QUOTE="Coopers_Dad, post: 1064162, member: 16511"] When I'm towing and sometimes when I'm driving unloaded a 6-5 and 5-4 downshift will happen with a significant thump. The rest of the time the trans is smooth and quiet. I've had it at the dealer twice and all they did was check the fluid level and scan it for codes, both of which were fine and clear. The truck has about 75k on it now. Even with an upgraded trans in my SRT it doesn't shift nearly this hard. Ideas would be greatly appreciated. [/QUOTE]
