I have 66 mustang with the i6 200 sprint and C4 transmission. it seems when i shift in to drive it seems that my transmission starts in second gear. and it wont excelerate. when you floor it it shifts down real quick and it then shifts back to second gear. i have replaced the vacuum modulator and tried to adjust the kick down cable. the timing is correct and the valves have just been lashed. i replaced teh fuel pump. i cant thank of any thing else. any one give me any other ideas i am open. thank.
