Hello guys, I have a sonata 2006 with 2.4l automatic with gas installed, since this is my car, I've had it for like 6 months now. And I got an error code (the photo attachment). The problem I'm having is when I put either in reverse or drive my car just like shakes one time. I've been to 2 mechanics and neither of them have solved the problem. I have like almost no knowledge about cars, but what I've read in forums, that basically I have a tcm(transmission control module) in my car, and near that tcm(or inside) is a relay which is malfunction or some problems with it. Am I correct? And also I tried to locate the tcm module, but couldn't find a specific location for it, and searched my car and couldn't find it either. And the only service manual I could find on the internet was like 15 dollars, so maybe someone could explain where the tcm is located ? And like how should I solve it. Can it be done by myself or should I send it to a mechanic. Would like to save money and do it myself. Also since this problem is present, my car is in limp mode, which means I only drive in third gear.

Check fuse box locations in manual & look for TCM relay from the diagrams. Swap with a non-critical identical relay if present & reset code to see if it reappears.

If you can't follow these directions ask Advance Auto/Autozone for help swapping the relay only if you buy it from them. They should also reset the code for you with an OBD2 scanner.

Best of luck!

Okay, so fuse#10 just an empty slot, so should it be full, and that's why it's having its problem? And we'll, I've tried to locate the tcm fuse, I've found 2 fuse boxes in my car, and I'll attach the diagrams in the picture below. Could anyone tell me which would be the problem? Thank you in advance guys.
