No it will fail, i had same problem on my old 1.6sx bravo and it was the speed senser in the gearbox, i would get it sorted asap as my speed sensor then wiggled though and managed to destroy 5th 4th 2nd and 1st gear leaving me with only 3rd and reverse to drive home from wales (i live in york so thats over 500miles!) haha
oh the joys of when i was a fiat owner!!
Now a 200SX owner
