I think I've solved part of my problem. I was going to purchase a valve body and send it to Broader Performance in Texas to have it altered with mild shift improvers. This all being done to hold up to the stroker motor that goes in shortly. I ended up finding a shift kit!! Can you believe it?!? Transgo used to make a kit and after 20 or so phone calls I was given a phone number of a place that specializes in "outdated" automatic transmissions. The guy buys the kit, SK 3VL, from shops that are clearing out discontinued parts. He even had more than one! If anybody wants the info on the place I will post it when his business card comes inside of the package.
I guess you just have to know where to look to find performance parts for the Cruis-o.
