No, as long as the engine is not running hot it will not bother the transmission.

Where at in a 1991 Honda accord lxi is the transmission fluild why does the engine run faster at times than the car is really going?

You can find the dipstick for the transmission fluid of an automatic transmission on the passenger side of the engine block (this is where the automatic transmission is mounted). It is way down in there and somewhat difficult to see - a flashlight will be helpful in locating it. You need to be careful when checking it because it is easy to burn your arm on the radiator hose as you reach down in there to grab the dipstick. As for the engine revving, depends if it is an automatic or manual transmission. If it isn't the clutch or the transmission, it could be a faulty throttle position sensor, bad oxygen sensor, bad fast idle thermovalve, or many other things.
