i have driven an 04 6.0 with a 6 speed and have noticed that at low speeds when disengaging the clutch its quite noisy, i dont mind this i am just wondering if it is normal. also does the 02 do the same? how do these 6 speeds hold up under performance mods?

 

Define noisy. Mine growls at low speeds, remember that the engine is only at about 650 rpm. when I disengage at that low a speed, I get a 'clack-clack' as the driveshaft unwraps from the rearend, and slaps the other edge of the pinion. Feel free to insert your own noise here.....

 

i am talking of the same noise that you have described, i just want to make sure that this is norma. i am in the proscess of selling my 96 f350 and am in the market for an 00-03 f350 with a 6 speed, just wanted to know about them before i bought one

 

There is allot of whirring, thumping and noises with a Diesel on a manual tranny. Just so there is no grinding or bearing noises....
