    is the transmission fluid low? let's hope thats all it is because all the other possibilities probably indicate a significant repair is required. pretty sure you check it warm with the engine running . do what manual says for checking it and filling it if it's low. pretty sure it should be a nice healthy pink/red color too. anything beyond topping-off the ATF fluid is probably best left to professionals.
