Shifting issues with M6800

[matt86]

I bought a used/single owner 01 M6800 last fall. All around it's in good condition. Has about 4600 hours. Besides some wear and tear items I'm replacing, I'm trying to get the gear shifter straightened out.

Those that don't know, it's a 8 speed, 4 high 4 low. Doesn't matter if it's in high or low range. Shifting between the left or high side of the H pattern (1/2 to 3/4 or vice-versa) is very difficult. Like it doesn't feel like it doesn't go between. I've only pulled the access cover off just below the lever. Linkage seems tight/no slop.

Has anybody else had this issue with a 6800,8200, or 9000?

Need to known exactly which model you have, there are several variants.

Do you have the WSM?

I do have one, forgot where I bought it from. I believe it is a M6800HDC. Cab, 4wheel drive, loader. Just looked around online about my serial number, dont think the dealer gave me the right one, its 61xxx. Missing a letter in there right? Or did that only start in '12?

Give me your serial number and I'll see if I have the right WSM.

Year+ later bump. Thought I had updated this post last year after an equipment company came by and looked at it with me. For those that find this thread here is the latest.

I forget which shaft it is (first or second shaft) in the transmission is sliding a little bit inline and not staying still. This is causing shifting to the right side where 3rd and 4th are located nearly impossible. When we took the access cover off we found the first and second shaft, gears, syncros, visually appear to be in good condition. Shift forks are not bent/worn as well. Syncros still have life in them per the mechanic. When he held the shaft forward you could shift between all four gears with ease. Looking at the transmission parts diagram there is a snap ring at the end of it between the transmission side and the rear diff case. He theorized when the trans/rear diff are split there may be a broken snap ring laying in the bottom of the case.

I have not had the time and access to a shop building yet. Hopefully this fall/winter now that a friend of mine has his built.

For now I drive around in 1st/2nd in high and low range. Pulling a 10ft rotary cutter 3-low seems to be the sweet spot. 4-low when I can get to it seems like a jogging speed at PTO RPM and too bumpy for the land I mow.
