My engine light recently came on on my Hyundai Tucson 2005. I did a test and it showed me those codes: P0700 and P0741, what should I consider doing? I was thinking of doing a transmission fluid flush is the best idea

The P0700 means that there is a problem with the transmission. The P0741 (https://www.autocodes.com/p07... means that the the transmission torque converter clutch solenoid is stuck. Changing the fluid could help releasing the solenoid.

I had the same problem just today, checked the transmission fluid level and was low, added fluid to thel level, can you tell if this could solve the problem. thanks

It's possible. You have to reset the light and drive your vehicle, if the light comes back than there is something else causing the problem.
