Thanks for the info. At this point in the car's life I think I am just going to ride it out and see how many more miles I can get before it really gets bad. We have had this vehicle for many, many years and my wife now drives it pretty much as a grocery getter...no long highway or high performance trips anymore. The car looks great and still gets comments and runs and drives fine but realistically it probably isn't worth much more than what it would take to have the tranny rebuilt. I love wrenching on many things but transmissions are not one them. Again, thanks for your comprehensive comments.
