Have done almost all ford transmissions but for some reason,a C4 has never passed across my bench.The motor is basically a stock 351 W that presently sits in front of a FMX.Anyway,the case and tailshaft have a D4 casting number but haven't checked the date. There is no tag.Anything I should look for and what parts and kits are recommended?Any special tools other than the usual needed such as seal protectors,etc? Will the FMX flex plate work? Any other suggestions will be appreciated. Thanks!
