Check engine light code thats came up

Question

P0501 VSS I changed that
P0722 came up twice Output speed sensor
P0730 also twice gear incorrect ratio
And
P0715 input speed sensor
I'm assuming that I should change the other 2 sensors right. And should I not be driving the car until I change them?
Thanks in advance!!

Answer 1

Yes , when there is a input speed sensor and a output speed sensor , check the transmission fluid level. and the condition of the transmission fluid.  For these code the check the connection there is no signal reporting the speed
