Flexplate Match Another important consideration is the size of flexplate and bellhousing you intend to use.
All early Bronco C4s were column shifted. One full rotation of the input shaft equals one full rotation of the output shaft. To reduce line pressure, counterclockwise. Lubricate the thrust washer with transmission assembly lube. Ford says one full turn either way adjusts line pressure 2 to 3 psi. At 3 inches of vacuum, expect to see 138 to 148 pounds of line pressure in any forward gear. The C4 remains one of the simplest automatic transmissions ever produced, which means you can build this transmission with confidence if you follow instructions and take your time.
