juddering and jerking in 3rd and fourth gear like its running out of fuel

anyone got any idea whats wrong withn my series 3? when it gets up to 30ish it judders and jerks like its out of fuel, gear stick jams when it goes in reverse

Sounds like a fuel problem until you mention the reverse problem. It could be unconnected but it sounds like a gearbox is on your xmas list.

Oh...is it diesel or petrol?

the reverse problem is i put it in gear release clutch and it snatches, press clutch again and gearstick is jammed, got to select 4wd and low box to release it

petrol

Sounds like your gearbox innards are not too well, JamesMartin is the guy to ask, I am not too familiar with the cogs n' wheels inside the box.

yeah, it don,t sound good does it, cheers

checked the prop uj'sfor wear?
just a hunch at the mo..

Have you got any oil in your diffs and steering balls?

Have you got FWH fitted?

Does it make any noises, or does it just judder?

props are ok,

got oil in diffs etc, got fwh fitted, it don,t make any noises, it is just like its running out of fuel, if i stop, then set off again its fine in first, second, third is ok till its nearly ready to change to fourth, then the jerking and juddering starts, change to fourth and its ok till it approaches top speed then it starts again.

got oil in diffs etc, got fwh, no noise, first and second gear is fine, it starts jerking in third at medium to high revs, change to fourth and its fine till it gets to medium to high revs

have you tried medium to high revs in first and second?

yes, its fine, its just 3rd and 4th, plus the gearstick jamming in reverse

:scratching_chin:
forgot about the reverse issue.......

fixed it, it were only the gearbox fooked!!! series 2a gearbox has done the trick.
