Hello, I live in France and I have a '63 riviera with a 401 ci and a dinaflow transmission (twin turbine) .it need a driven gear but I can't find this parts (my speedometer don't move when I drive the car).I try to count how many teeth are there on the drive gear and I saw 3 or 4 ,is it possible??:clonk: I hope some one can help me Thank you very much bye

Are you sure the cable is not broken? Spin the end of the cable by hand at the transmission end and have a friend watch the speedometer. The speedometer should move if the cable is not broken. Spin it both ways just to be sure you are spinning it the right way.

I test the cable it is OK ,when I spin it the speedometer move on.
I take off the driven gear housing and the driven gear is not there!!
So I would like to find one but I don't know where.I look in the transmission and count how many teeth is there (3 or 4) and try to find the right driven gear .And it's for this reason I wanted to know the axle ratio. Bye
