There are a couple of things to rule out before you replace the shift computer. Make sure that the vacuum line to the modulater is connected and not leaking. Check and adjust the line pressure. Check the level of the trans fluid and smell it to see if it is burnt. Also check color. (It should be red without small black bits in it). Check the cable adjustment to the shift computer. Make sure all of the connections to the shift computer plug are clean and tight. In the end it will probably be the shift computer but you will kick yourself if you wait for it, spend for it, go through the work to put it in, and still have the same troubles. Mileage doesn't seem to be a major factor in failures of the shift computer. You do not have to drop the fluid and pan to replace the computer but it is a good idea to peek inside once in a while.
