Try looking for an AOD transmission. They are called AOD or FIOD. You can find them in many ford cars and trucks. They came out in 1980 and up to 1992 had no electronics except for a neutral saftey switch. From 93 on they are all electronic and switched names from AOD to AODE then 4R70W. They are not hard to find and are not that much more expansive to rebuild compared to a C6. The only thing you would need is a throttle valve cable. It is in a way like the 700R4 in that it has no modulator and works off throttle pressure. Hope this helps.
