The torque converter expands beyond its limits putting excessive pressure on the flex plate which over time cracks. To illustrate did you ever take a can of soda, crush it then take it in your hands and fold it back and forth? What happens? It cracks and if you continue you rip it in half.

So would a tranny cooler help? If not any suggestions ?

Check for loose bolts first.
Take off the little shield at the bottom and use a big wrench to turn over the engine so you can see each bolt.
I used a 2 or 3 foot 3/8ths extension to reach the bolt to torque them in.
