Thanks for keeping on my toes.

Again my point was missed that this car has a long life transmission fluid in it and why go through the expense of changing it just to have something to do. Goes along with my comment of spending thousands of dollars on the car to make it go better when you could put the thousands of bucks with the cost of the car and buy a car that comes from the factory like you want.
