05 frontier in limp mode no codes transmission just replaced
If you paid a professional to replace the trans, go back to him first so he can give his opinion. Before you do, check the fluid level of the trans, and the condition of the fluid. Any sign of water?
But the problem may not be the trans, there could be faults in the engine or cooling system causing the ECU to select limp mode to get you back home.
Have you scanned the computer directly with a scanner?
Don't rely on the check engine light for very thing relating to codes.
