Making a mistake in the tasbeeh of ruku' or sajdah

In salah if I make a pronounciation mistake in sajda or ruku while reciting the tasbeeh first time or second time and if I correct it in the third time, will the salaah be still valid or the moment I make a mistake in sajda or ruku the salah becomes invalid. If the mistake happens in sajda or ruku, if I correct it the total tasbeeh becomes 4 times and in other sajdas it will only be 3 times. Does this difference effect the validity of salah and how to correct myself when I make mistake in sajda.
