I have a 68 mustang fastback with the original 289 engine and automatic transmission. The two barrel carb has been replaced with a four barrel carb. The rear end is original. I would like to replace the transmission with a one that has overdrive. Any suggestions????
I got you covered, just buy all the stuff listed here and then get a rebuilt Ford Automatic Overdrive transmission (available from 1980-mid 90s): https://transmissioncenter.net/shop/c4-aod-swap-kit-1965-1973-classic-mustangs-aod-conversion-kit/
Don't forget to do a constant pressure valve body as it will save your bacon as it will give you a constant line pressure and the T.V. cable will in effect be a kickdown. A misadjusted T.V. cable will burn up an AOD quickly. Aside from that, enjoy it. They are a good transmission.
