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!

Have to pressure test it... but it fits well and is about 3/4" thicker...
so must be better at cooling eh?
