My 96 Ford Windstar transmission was rebuilt some time ago and it has developed a surge/bucking feel in overdrive at about 1400-1600 rpm. I have tried to isolate whether this problem was electrical or mechanical over the last few months. The #4 fuel injector has been changed along with a new set of plugwires and double platinum plugs. The engine has no noticeable miss at idle or acceleration, but as the transmission drops in to overdrive and rpm settles at around 1500,you get severe bucking until you change the engine rpm - problem disappears - then returns when idle drops back. I have tried driving in drive only(third) and although the rpm is higher, the problem still returns. Any ideas on whether this problem is electrical/sensor/computer/or transmission related? The trouble light is not on and a buddy of mine checked for any codes and said there were none showing up. One suggestion was warpped plates in the torque converter, any and all others appreciated.
