Hello!

I went to autozone today to pull the check engine code that recently flashed on today. The scanner pulled two codes...

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

So it could be either or both as a potential problem.
I do have tranny problems, for some reason when the car changes gears it seems like it jerks and has a hard time shifting, fluid has been replaced but still no effect.

My question is, is this seem like an electrical problem? Can I fix this myself? "Control system" seems like it is an electrical issue.

Also, if it is fixable by myself, were are these parts located?

Thanks in advance!
