Default Just got 2 CEL Codes. P0700 and P0740. Help on fixing them please.

My CEL came on while driving on the highway. It didn't drive differently, nothing feels different at all. The transmission shifts like it always did. Any ideas?

If you reset the ECU does the CEL return?

my apologies! lol what car is it? and is anything done to the car?

so you said it appears to still have overdrive? and shifts smoothly?

have you checked the fluid level? or driven in any strange conditions or had the car serviced recently?

It's an EJ8. Only thing done to it is an AEM intake. It shifts smoothly, fluid level is fine, no strange driving conditions, no recent service.
