I have an 99' with automatic and it sometimes seems to take a long time for it to shift from first to second and also third. Some times I have to let off of the peddle for it to shift. I change the fuild and it still does the same thing. It doesn't do it all the time, it does seem to be doing it more often. Is there anything that I could check ? I do recall something about a throttle positioner may need clean. Is there any suggestions.
