There is an ad for this car and the person says the TCU quit working so the car will only get up to 2nd gear. So, what is this, and how much would it cost to repair it? Is it safe to continue driving the car and will there be any further detriment to the engine if one drives it in this state, just in 2nd gear?

Last first, it probably won't hurt the engine, but it could further damage the transmission to continue to drive this crippled car. It's possible that the TCU is the only problem but I know there could be internal problems in the transmission. Who diagnosed the car, the owner? How long has he been driving it this way? The 'limp in' default mode is for getting you home or to a shop ASAP, not to allow you to drive it as if nothing were wrong at all. Check the trans fluid, if it's black or burned smelling, the transmission has overheated at the very least and is probably damaged.
If you really want to buy this questionable car, get a guaranteed estimate on repairs from a reputable shop, which pay for. Then buy the car real cheap because these cars are not easy or cheap to repair. There is no way for me to tell you what's wrong or how much is it will cost to repair it without diagnosing it myself.

Thank you. That was helpful information. The owner said the engine was rebuilt and it's been parked since the TCU went out. I will definitely call a mechanic to get an idea of what to expect. Thanks again!
