JD 6600 shutle engaging problems

[Maquinista]

Hy gents,
Got a 12k H JD 6600, with a powerquad and 5 speed range TXM, as far as range module concerns no problem at all, same for 4 speed power shift.
Whatever goes wrong with it, its on the FWD/ RWD shutle. Specially FWD it does not engage well, specially if clutch pedal is depressed.
RWD engages well either with clutch depressed or not.
Shutle lever is on right side, and park position on the range lever.
BTW, it quit starting from key. But after this situation started to come along. Of couse Starter is bypassed and tractor starts fine and runs fine, just this issue?
Gents got any idea to start digging?

Start with the simple things, and make sure the cable between the lever and gearbox is adjusted correctly, and moving freely

Yes check the forward/ neutral/ reverse cable linkage for correct adjustment. Doesn't take much either way for it to cause lack of drive in one direction or other

Right or left hand shuttle ?

Could be broken clutch cooling springs in the valve body underneath. Just done 6210se.
springs brake jamming the spool. Need to unbolt the shift housing from trans and inspect.

Well that might be the case, actually i´ve ben harrowing some heavy brush and it might have bent something underneth.
The bowden cable has some play, but i always assumed when time come it would not shift at all. Problem is only hapens with clutch pedal depressed.
Does this tractor has a dedicated main clutch? Or they just clutch on the Shutle Packs?

Hum, by reading here and there got the idea that this 6000 GEN Powerquads differ in that matter from the 6010´s. Can u explain a litle more in this regards?

Thanks to all.

Crawl under the tractor and look around. Rule out the simple stuff
