Check the "kick-down" linkage for proper adjustment first. After that, change the filter. If you can not find the factory canister filter replacement, remove it and use a 64-65 type "in pan" filter instead. You may find that the current in pan filter screen may have come loose and allows the unit to suck air on the curves & hills.
If all that stuff checks-out fine, the next move would be to swap-out or rebuild the valve body.
