ok so I am looking at a 63 falcon with a 170 and 3 speed. Old age and bad knees so I need an automatic trans Will a C4 work and what do I need to change it over? Thanks...
Easy would be to find any 70's 200ci C4. Also the block plate, starter and driveshaft yoke as the C4 may have 24 or 26 output spline, I'm guessing the 3 spd is 10 spline? Can use any of the 64-81 170/200 C4s but the later 70-up units will already have the updated bits and be more plentiful. 250/300 use the Windsor bellhousing. This won't work with the 177/200.
Adding a auto ******,to were a factory standard was,will most often need rearend gear change also. The factory rear for standard shift [ higher #] is lower then,factory auto. gearing=[lower number ] Standard shift rear gear with auto ****** will cut MPG,so you buy more gas! Still it will work,with out fooling with rearend at all,just MPG drops.
Its called getting old and your wore out, abused, body is telling you so, but you still want to drive your old rides. If you don't find that out in another 15-20 years, consider yourself lucky.
If you keep your engine, be sure to remove the pilot bearing from the crankshaft. Also will need to add transmission oil cooler unless radiator has provisions for the cooling lines.
