Dennis, thanks again, it's not that I'm not satisfied with the automatic, so much as it the fact that I am having difficulty getting it to perform as it should. From the beginning, I ordered a master rebuild kit and also a shift kit for the tranny this spring, I rebuilt it according to specs and several books I purchased including Ford's shop manual for C5's. When I installed it and tried it, I had no reverse, pulled it apart and checked everything, couldn't find anything wrong. re-installed with new seals and plates, still no reverse, checked pressures at the port and everything checked out OK, pulled it again and tore down, everything looked OK, put it back together and sent tranny down to transmission shop, 100 miles away, very respected shop, lot's of recommendations. He tore it apart and said everything looked OK, except the torque converter had a problem, he cut the torque converter in half to take the weights out for overdrive, because he said they were a problem, but someone had beat him to it, they were already gone. So I realistically had a C4 with C5 guts. He put it on the dyno and said it worked fine. Installed it and lo and behold I had reverse, but, when I first take off with it in drive, it will not shift into second until I reach about 35-40 mph, this is not floored but just slowly accelerating, then it will not shift into third until I am going about 55-60 mph. After it warms up, it shifts into second at 10-15 mph whether I'm going easy or floored, and shifts into third at 35-40 floored. I have adjusted the modulator several times and it still does the same except when it gets warm, I can increase or decrease the shift rpms with the adjustments. Also, if I take off in drive and let off on the gas before it shifts to second, it will go into neutral and I can rev it up, if I floor it it will go to about 3500 rpms before it comes into low again. So, I have a C4 also to rebuild this winter. I'm outta here
