Below is a severe example of what often happens to your Accord TCM -transmission computer. Sometimes the capacitors will simply corrode and destroy the printed copper traces on the circiut board without the resistors or capacitors catching the TCU on fire.
Symptoms will vary depending on how the failure is taking place, or where the corrosion is settling in. Trouble shifting, S or D light issues and high gear only(fail safe mode) are good indicators that something is happening with the TCM. It is common, it is a given at some point for every Accord owner.
