Does yours chatter at low RPM or when you lug your truck? I mean chatter as in making a chattering noise like the '99-'03 Super Duty 6-speed PSD's do, but not quite as loud.

My IDI has clutch chatter.

 

mine has absolutley 0 of that in fact when my uncle (zx250) drove it he was amazed by how smothly my tranny shifted and worked he said it was smoother than his his is a 99 7.3 and has a sonnix shift kit

 

I Did the SMF Conversion, and "Chatter" is putting it mild. At Low RPM's, or with the clutch pedal out and tranny in neutral it sounds like a bucket of marbles rolling around.

 

You have a 5 Speed? I thought you had a E4OD.

 

Same with me.

 

No sounds outta mine, the fly wheels knocks harder than an old Chevy 305 when you turn it off with the clutch engaged in neutral, but other than that, seems to be fine, even with the mileage that's on it, reverse can be a pain some times.

 

You still have a DMF, right?

 

Yup, everything in my drivetrain is all original. Never been touched.

 

I question the use of chatter here ... You will feel chatter through out the whole truck, the dash will dance and this only happens when you are taking off slowly letting the clutch out.

The rattle you get when lugging a Diesel (Strictly a NO NO) is the Diesel pulse slamming all the drive train slop back and forth destroying everything from motor to axles! You'll most likely hear it in the transmission. This does not mean there is a problem with the truck!

This is called gear rollover rattle, not chatter!
Either put the DMF back on or fill the transmission to the top and kiss your transmission goodbye in time. How long depends on how much you let it idle in neutral, though I must admit it'll likely out live any of us unless you live in a cold region that you never shut your truck off in and it spends horrendous idling hours.

ya didint relize he was a 5 speed till after i had posted im going crazy lol

 

I want to switch to a SMF cause my clutch and DMF are done for and can't afford a new DMF. what i understand from this quote is if i change to a smf i'm putting a death sentance on my tranny?

 

it clatters with the smf, it did it bad with the dmf, and clunked when i shut down. the smf clatter is normal. thats why a lot of guys try and keep hold to the dmf as long as possible.
