I have a 99 Integra GS with Automatic tranny. My ECU came on and threw codes P0700 and P0740. How do I got about fixing this issue? I know I can just reset the ECU, but need to know what i need to replace and cost. Everything seems to be working fine and start up fine.

Here are the descriptions of the codes:

P0700 Automatic Transmission Control System
P0740 Problem in Lock-up Control System

I would appreciate anyone's input and expertise.

 

oh boy
