FO202 Ford/Mercury FE 410/428 to Ford Small Block AOD Transmission



This kit will also work for a C5, C6.

If you plan on using a C4, be sure that you have the larger 164 tooth flexplate style bellhousing (Ford also made a 157 tooth version). An easy way to check that is by measuring across the inside of the bellhousing to see if the 14.25” O.D. of the 164 tooth flexplate will clear; the 157 tooth flexplate is about a full inch smaller.

(1) *Balance Weight for SCJ or CJ428 Applications Only

*Due to the precision of the SCJ and CJ 428 we will provide you with the counter balance weight for the flexplate. However, it will come as a separate piece and will need to be balanced with your rotating assembly to ensure accuracy. This is not a capability we have in house.
