Good luck and let us know how it works out.
A side OT note. My son's 97 Blazer with 4L60E tranny at 100K miles was doing a slam hard 1-2 shift after it got warm and was flipping in and out of OD at will. Shops wanted $1500 to tear it apart after I explained the symptoms. I researched on the net and called shops to find out more about the 4L60E. It turns out this was a normal thing after 100K (like clockwork). $200 for a new valve body kit and it shifts like a dream.
