This car has only 69.000 miles on the odometer, but the owner had a friend, you replace the carburetor with a normal CA. The car is not in 2nd Gang go h at 31 km / and will not go into overdrive until it is up to 71 MPH. What we need to change it, to get the transmission to shift properly? Thank you for your help.

The car is no longer in California, it's OK to change the carburetor.
It is a very nice car, white with red velvet interior and all the bells and whistles, then I really see it just sit. PLEASE suggestions. Thank you again.
