Trans has a fresh rebuild which includes a reman valve body and rebuilt convertor. Everthing seems fine on 1-2-3 shifts but SOMETIMES at 35 mph when the convertor locks up it will shutter? Is this a bad convertor or another problem. Fluid is at the add pint line hot idling in neutral with type f valvoline fluid which I dont feel to be an issue. Any suggestions? Thanks in advance!
