Since you have an auto trans fit a thermostatic bypass oil cooler on to the auto trans. It is important that the trans fluid still goes through the cooling coil in the bottom of the radiator (It warms the trans fluid up to operating temp!) but have a separate oil cooler that the trans fluid is shunted through by a thermostatic valve if it gets too hot - thus cutting down on the heat pumped into the water of the engine cooling radiator and keeping the auto trans fluid at operating temperature.

The 2.2 motors sometimes were fitted with a 4-speed Over Drive Nisin-Warner auto trans in the cars they were fitted to originally. I am trying to adapt an Isuzu Piazza auto trans of the same type to my 2.2 motor (2.0 with 2.2 crank) as the increased torque should drive the OD gear nicely!
