Hello
Thanks for the donation

Do you notice if the OD (overdrive) light is on or flashing? This usually indicates an electrical problem with the tranny. A sensor would be suspected if this is the case and a reputable tranny shop can run a diagnostic on the vehicle for around $50. The diagnostic fee is much cheaper than paying out thousands of dollars in replacing the tranny with a new or rebuilt one.
