Help, Gearbox rattle in 2nd and 3rd gear

[Tractor ted]

Went and looked at a b1400 today, mint and very low hours but a very bad rattle banging type noise when in 2nd and 3rd gear, worst in 3rd, hi/low makes no difference. Noise still present. Like a shaft rattling about and slapping off something when clutch is released in these gears, 1st and reverse are sound. Any info hugely appreciated as im very interested in this tractor if its not a huge problem to sort. It also jumped out of 3rd gear at one stage when i left out the clutch. Info massively appreciated folks.
Thanks a million,
Kevin.

The B1400 is grey/gray market to us here in the states so little first hand knowledge of them, but if it's like most all of the other B's your looking a doing a transmission rebuild.
If you have good mechanical knowledge and time and space you can do it.
I've rebuilt several Kubota transmissions and they are pretty strait forward.
Get the WSM for the tractor and it will give you the complete break down of the inner workings.
As far as price goes, it could be cheap or it could get real expensive, I bought a tractor with a damaged case and it was $1K + just for the case there was also another 1K in other parts to finish the rebuild.
