    About month ago I had shop mess with clutch linkage and now it it's harder to shift transmission, particularly from 9 to 10th and 10 back to 9.
    Low range gears seems like once I shift gears it will jerk forward between gears.
    This is eaton Fuller 10speed and I float gears most of the time. Guy didn't adjust clutch on the adjuster nut but instead messed with clutch linkage and brought clutch pedal up as far as I remember.
    He said "there's too much clutch brake" as he adjusted linkage rods which brought pedal up.

    Ask the Expert: What is the correct way to adjust a heavy duty clutch? | Vehicle Service Pros
    Short article. You can check the 1/2" between release bearing and clutch brake yourself as well as the 1/8" release bearing to release fork. Should not ever have to mess with the linkage. I've adjusted plenty and never touched linkage.
    It's harder to shift even when floating or only when using the clutch? If when floating then you have other problems as you are not using the clutch when floating gears. There is a spec for pedal height if you can find it or get it from someone.

    It's actually both. Hard to double clutch and when floating it sometimes doesn't want to "release" from one gear to another

    Check the adjustments.
    Bing Videos Go to the 3:25 mark in the video. It shows how to check the adjustments. You could buy a 1/2" wood dowel at Home Depot etc. to check the release bearing adj. Or use just about anything that is 1/2" wide.

    1/2 inch socket extension works well.

    It's interesting to point out that it became harder to float gears after mechanic messed with the linkage.
