1st thing in the morning, 2 days in a row, get 2 miles from home and the RPMs drop to 900 and the transmission drops to 1st gear. Accelerator pedal has no effect at all. Turn engine off/on and light goes out and drives normally. Naturally, the dealer can't duplicate the problem. Any ideas ?

 

What year?
