I am sorry for the long waitusually when these transmissions shift this way there is either an issue with the TV cable from the carb to the transmission out of adjustment or there is something wrong under the pan of an accumulator spring or sticking valves in the valve body or a check ball issue or the channel plate under the valve bodythe best action is to adjust the TV shift cable off the carb if it still does this the valve body and check balls and channel plate need to come down and be inspected including the accumulator springs as a lot of those springs can break and cause this issue
