5 speed / 6 speed ?
Hi I am new to the list, and am very excited - it seems there are lot's of very smart Ford lovers out there!!!
K: I have an '00 F250SD - 6.8 V10 - 5 spd manual trans.
I love the truck, but want a 6 spd manual.
Anyone know, can this be done? How difficult ? Would you recommend ?
Any help is appreciated!
Peace,
Mike

Less FWY rpm ...
Ken thanks for the quick reply. Looking for less fwy rpms. Need to know if later model 6spd manuals bolt right up to a 2000 w/ the 5spd manual. And if it does where can I get one? Any ideas?

Weclcome to FTE , Michael! Gald you found us all here! 
The difference between the ZF-5 & the ZF-6 overdrive ratio is .04.
The ZF-5 is .76:1 and the ZF-6 is .72:1.
Is it really worth the expense to swap for a lousy 100+/- rpm difference at 60mph?

You guys are absolutely correct - it would be crazy to swap a 5sp for a 6sp - for a lousy 100rpm.
That said, what would you suggest? I don't do a lot of towing, but do drive the truck a lot on the hwy. Just looking to save some rpm's. I realize it's not a honda civic but you can't blame a guy for trying to save some $. Already have larger wheels/rims. I'm thinkig chip? or gear swap? It's a 4wd. Not sure how to identify the differential ratio. Actually, never messed w/ transmissions & don't know where to start. I appreciate any ideas or pointers. U guys are OK... <M>

lower revs is NOT necessarily better for an engine.
Ask the I6 guys with 35s and 2.73 gears. They get horrendous mileage and guys with 35s and 373s get better mileage. It's all about staying in the powerband of the engine.
Having a 4x4 is the ultimate strike, being so aerodynamic (yes, sarcasm).
Chip will need premium (unless you have to run that in a v10, doubtful) no matter what and doesn't do much for a stick shift, unlike how it firms up shifting in a slushbox.
