My first suggestion would be to pull up the drivers floormat and look under the accelerator for the kick down switch and make sure it's free, or even unplug it.

If that doesn't fix it, open the hood and make sure the Bowden cable is attached to the linkage, and moving freely.


Next I'd drain the pan and torque converter of fluid, and refill with cheap Walmart brand fluid, get the fluid level correct at operating temp on a level surface.

This way you know what is in there.

Next get a bottle of trans-X fluid solvent and drive for a week or so, then drain the fluid again and drop the pan and change the filter and gasket. Refill with high quality dextronIII fluid.

If no improvements are found after this... Consult a transmission rebuilder.
