I had a nearly identical accident, and right around the same time too. About the second or third week of September, I was on my way to school one very rainy morning. Traffic on I-49 started slowing down, but then went from slowing down to IMMEDIATELY stopped. A small Honda right in front of me went front doing about 30-35 to suddenly locking up her brakes to a dead stop. Of course I can't stop a 18 year old Suburban as fast as a small Honda can, ESPECIALLY in the rain. So I plowed right into the back of her even though I tried desperately to stop. It honestly felt like l just bumped or tapped her, the impact didn't feel hard at all and the airbags didn't deploy or anything. Her car had VERY minimal damage to the rear bumper cover and trunk trim. After I pulled off the highway, I was stunned to see that my bumper, grill, and all the lights were all completely destroyed, the hood and driver side fender are both bent a fair amount, and I had transmission fluid spewing EVERYWHERE because the trans cooler busted open.
The lil Honda was able to drive away and go about her business, yet I had to get towed to my house because I was bleeding red fluid everywhere.
(BTW, after I repaired the lines and topped off the transmission fluid, it took almost 6 quarts to get it back to normal operating range.)
