Ok, unless yours has an aftermarket transmission oil cooler, the factory one is integrated into the radiator which means you have to replace the radiator

  1. Remove the air duct.
  2. Disconnect the negative battery cable.
  3. Remove the air cleaner assembly.
  4. Drain the cooling system. Remove the radiator cap to speed draining.
  5. Remove the inlet hose from the radiator.
  6. Remove the transaxle oil cooler lines from the retainer clip at the bottom of the cooling fan shroud.
  7. Remove the fan shroud clip from the condenser tubes.
  8. Remove the bolt that connects the fan shroud to the condenser hold down bracket.
  9. Remove the air deflectors from the top of the radiator.
  10. Remove the cooling fan shroud bolts.
  11. Remove the coolant reservoir hose from the radiator overflow neck.
  12. Remove the radiator upper support brackets and bolts that connect to the fan shroud.
  13. Disconnect the engine cooling fan motors electrical connectors.
  14. Remove the cooling fan motors electrical harness from the fan shroud clips.
  15. Remove the cooling fan shroud.
  16. Remove the outlet hose from the radiator.
  17. Disconnect the transaxle oil cooler pipes from the radiator.
  18. Tilt the top of the radiator rearward.
  19. Remove the condenser hold down bracket from the radiator.

After removing the bumper cover I found that the original Trans Oil Cooler was NOT part of the radiator. I was able to remove the original cooler and replaced with an after market one. So your recommendation that I would have to buy a radiator was incorrect. I can not give you a rating at this time.
