I love my six speed. However, the factory pilot roller bearing is crapola and should be replaced with a nice Kevlar bushing. If you like the stock pressure plate, wait until you use a LUK or South Bend clutch with the larger diameter plate. They come with a flywheel to make it work. When I first did mine, I almost shoved my foot through the floor- the pedal effort was that low. It has firmed up a bit, but not as heavy as stock. More clamping force though.

When you get about 10,000 miles on the fluid, change it to Mobil 1 and add a bottle of friction modifier to it .It will quiet it down and make it shift even better.

I have a 2000 f550 with the zf6, and am having trouble with it jumping out of OD when you let of the fuel... 136k on the clock. anyone suggest what may be the problem? When it jumps out you have to shift it to neutral before it will go back in, otherwise the gear grids,but if you let it go to the neutral position, it will go back in OD no grid

The funny thing about having this transmission in my 2010 F250 is that people either understand exactly why you like this type of drivetrain, while others can't understand why anyone would want to be constantly shifting gears! I will say that people who are not truck oriented are very intimidated at the thought of driving the huge pickup with the 6 speed.

This is my favorite picture, so don't be surprised if you see it in other topics.
The 6 speed manual in this truck has over 220k. It pulled the set on the picture a month ago on 5%, 6 miles long grade east of Las Vegas, where lot of vehicles rest on the shoulders with hood open in 100F heat. I kept my right foot on the floor for about 1/2 hr at the time every hour.

I have a 2001 f350 ext cab 7.3 6spd with manual 4x4 and all the accesories (very hard to find around here). over 200,000 miles with no problems at all, P.O. has a 5th wheal on it with extra leafes and air bags in the rear, so they where hauling some heavy a$$ trailers.
I recomend going to dieselsite.com, they have a screw on filter assembly that goes on the cooler lines. I am going to do that soon (about $100 for filter assembly, and then 10.5 for replacement filters.)
I have heard some news about the pilot bearing issues, some say it is all the 6spd trannys, someone else said it is only the diesels, and someone else said it is just the 10 cylinder. I have yet to clear this issue up though.
the only down side I see is that the 5 spd has 2 pto covers and the six only has one, but do you really need 2?

vze,I just love posts like this and this thread! My, I'm getting to the point of being a dinosaur with my manuals and everyone telling me your not in the stone age anymore? I'm on my 3rd manual 250. First 2 were 5 speed, my 02 is 6 speed and all with 4.10 gears. The 6 speed takes a little getting used to even to a person like me with a stick all my life. My 02 is at 180K with not one problem with the clutch or tranny, enjoy yours and tell the naysayers with autos my tranny will outlast yours 2 to 1
