4R70W shift question
Factory Tech Valve Body
If you can do the work yourself, you will have less than $300 in the whole job -- including the oil and filter you will want to replace while you are in there.

Sidewinder,
I had a chip which improved shift firmness, but by increasing the pump pressure. I switched to the Factory Tech Valve Body when I got rid of the chip, and I am very happy with it. Check out their website and you will be impressed. Also, service is outstanding.
