Normal for the M5OD?
Hey there,
I have a 94 f150 with the 302 engine and M5OD manual transmission. I did an engine swap and replaced the clutch when i bought the truck about 4,000 miles ago (2 years). I know these transmission’s are not known to have the smoothest operation, but it’s pretty bad.
here is what i mean… the clutch engages at the top of the pedal which is fine, but it only releases at the very top as well. It has a very tiny window of grabbing (not sure what to call it) it’s either clutch fully engaged, or clutch released at the very top.
After driving the truck for 2 years im pretty used to it, and it generally doesn’t give me many problems because I know how to drive it. But if ANYONE else drives the truck, even if they drive a standard trans, they have a super hard time.
Wondering if there is any sort of adjustments that can be made. Was my clutch installed wrong? Is this just normal M5OD operation? Thanks for any replies.

Could be a bad slave cylinder.
My 95 is pretty linear for how it grabs.
I knew a guy 20ish years ago that had an 88ish truck with an M5od that acted the same as you describe. Never did find out what caused it. You could look up under the dash and see if the bushings in the pedals are worn, that would be a good place to start.

1-2" of pedal travel before the clutch disengages is great(I think).
As the clutch disc wears, the pedal will travel farther.
Brand new parts, zero slippage, its grabbing, that's great.
If clutch disengages with half pedal travel or lower to the floor, I would then be concerned.
There are a lot of people that 'say' they can drive stick, then there are the ones that truly can. Every vehicle is a little different.

while I do agree with this, I was taking his "no slipping, it is engaged or not engaged" into consideration. That is not normal. You should be able to slip the clutch. Now maybe he can and he didn't explain well. But, I have had performance clutches that were light switches. And let me tell you, that is zero fun in a truck. And that is how I was understanding the original post.
For me, it depends on what boots I am wearing, or running shoes. Cow-boy boots, I can't even walk in them, let alone drive stick with them.

I wonder if maybe the primary cylinder's not 'self adjusting' correctly-
if the plunger inside of it can't return all the way to the top of the bore,
it doesn't uncover the equalization port, and the system becomes closed.
Quick test is to have someone push the pedal down 2-3", then open the bleed
port just a little, and let just a bit of fluid out. If the clutch bite point then drops
and stays there, it's not equalizing. If it climbs back up to the top again, then
the hydraulics are working as designed.
I suppose it could be a radically too- big main cylinder- but it'd take a huge one
to go from stock to 'light switch' clutch.
The other thing- if there's a solid friction disc in there, those behave
a lot like a switch. Most friction discs have a wave spring in the middle,
to give a 1/16th or so 'give' to the disc so you can gently modulate it.
Some designs of dual- mass flywheels do that in the flywheel, and use
an unsprung friction disc. That's a long shot, but also possible...
...I mean, that there's an unsprung disc, not that there's a DMF for a smallblock.
