I just finished my auto to manual swap in my F250. Just thought i'd give a huge thanks to the guys here that answered some of my questions. Here's a brief list of how i made it happen.
-parts $2300 (all from same guy listed below)
-trans fluid $50
-Fuel in my buddies powerstroke for the 800 mile trip $150.
*(ALL LABOR DONE MYSELF)
Found a guy doing the opposite swap and i got all of my parts from him:
-zf6 manual trans
-clutch and flywheel assembly
-clutch master and slave cyl
-transfer case input shaft (couldnt swap the whole thing b/c i have manual t-case shifter and his was electric)
-clutch and brake pedal assembly
no need to go into elaborate detail about how i did it. I did NOT swap the floor humps. i just used a floor jack, some 6x6 blocks, and little patience and "finessed" it up. (had to jack it up to clear the zf6). then i measured and cut the hole for the shifter, it looks great and the carpet hides any minor imperfections in the metal work.
i also didnt swap the steering column. i just removed the old shift lever, and will be getting new covers soon to cover the hole. I will also be getting a new wiring harness for the trans, but for now i have just spliced the 4 wires that needed to be connected to "fool" the old computer into thinking that the trans is in park or neutral to enable it to start.
all in all, everything is working fine so far, and my only regret is that i didnt do this 3 years ago when my first of what would be 3 automatic transmissions went out.
A FEW OTHER NOTES:
your truck should already be "prepped" to take the manual set up. mine already had the holes through the firewall for the clutch pedal to bolt to and the master cyl to go through. it also was already wired for the plug that is on the clutch pedal (i believe to be the neutral safety switch). it was really a very basic transmission swap that isnt too hard for the average do-it-yourselfer thats a little mechanically inclined.
COLUMN REMOVED, (i later found out this wasnt required, but you do need to do it access the shift indicator to remove it.)
SHIFT INDICATOR REMOVED. (2 plastic squeeze tabs on either side and it slides right out.)
SHIFT INDICATOR COVERED WITH BLACK ELECTRICAL TAPE. (looks like a stock 6-spd dash!)
CLUTCH, BRAKE PEDAL INSTALLED.
