Yes the larger cooler should work better. Most of the heat is generated in the torque converter and it does a great job cooling itself with those attached fins. The water to oil cooling approach is a bit of an interesting set up. For the most part the transmission cooler is in parallel with the radiator. The coolant going to it is the same as that going into the radiator. It is the flow (volume) that determines the cooling capacity and when underway (radiator has sufficient air flow) the coolant flow will be dependent on load and speed. Higher load = more cooling!
