CEL fired and I pulled the code. P0743. So it's the solenoid I get that but what should I check before diving into the tranny. Also the light came on at a stand still when first starting up so that makes me lean towards an electrical issue. What should I check first? Fuse? Where is that? If I do end up going into the tranny can I do it myself? Most I've done is a fluid dump and change. Let me know what you guys think.
