How hard is it to convert a C-6 Automatic Tranni into a 4-speed Standard?

Question

How much would this cost roughly? i have a 1977 Ford F-150 with a 351M and a C-6 automatic Tranni.

Answer 1

#1) You want to remove the Automatic, purchase a Manual and install the Manual in your truck?

or #2)are you asking how to convert a Automatic Transmission to a Manual transmission?

The first #1 is Possible but a lot of work.
new Flywheel, clutch, pressure plate ...install pedals, hydraulic throw out bearing and cylinders, etc, etc.

If you have a donor truck/car from a salvage it will be much easier.

The Second i#2 is not plausible and won't happen.

Answer 2

Remove tailshaft, starter motor, speedo drive, kickdown, Vacuum modulator line(if fitted), cooling lines, crossmember, autotrans(with convertor), flexplate, brake pedal/pedal assembly. Install pilot bush(in back of crankshaft), flywheel and (longer)bolts, clutch & pressure plate, bellhousing, starter motor, gearbox, crossmember, shifter &/or linkages,speedo drive, tailshaft, pedal assembly(with clutch pedal), clutch master, clutch slave and line. Not hard but there is a bit more to it. Your cost should be no more than parts (gearbox, shifter, clutch, pressure plate, flywheel, pedal assembly , a few bolts here and there and oil). I live in Australia so I'm not sure what parts are worth where you live. PARTS for this truck are HEAVY so don't be a hero. Good jacks are a must to hold up a big 4 speed. An experienced mechanic working in the driveway at home could easily do this job in a day. You don't say if the truck is column or floor auto. If column, you can remove the shift stick or replace the whole column with a floorshift unit.

Answer 3

It's a pain in the butt. That C-6 is the best you can have. If you want to change your truck...find a 3/4ton Dana 60 with 3.50 gears and you will see a major improvement....unless you are currently running a 3.50 or 3.73 gear set.

Answer 4

A couple hundred of bucks if you know what you are doing. Maybe as much as $500 if you pay someone to do it. Note, don't do this unless you know how to do it already. It's not rocket science. But, it's not trivial either.
