I have a C4 tranny, with the removable bellhousing it also is the panfilled type with the dipstick in the pan, I can tell its a 70's model It was behind a stock 302 which I put in a truck and sold the truck but I kept the C4 ,Ive cleaned it up really nice painted it Ford Blue ,its all stock but I was wondering what is one of these worth? Are there any pros and cons to the C4 with case fill, or panfill ?
