JD 3650 Clutch Slipping in Hi

[Dermo23]

Hi I've a late 3650 40k here and the clutch is slipping in the high dual power its only barely slipping. When moving off you have to let the clutch out further when it's in high to get it to move the high low pack has been done and the clutch. It's been bled to death with no air left in it just wondering if theres an easy fix or is it the high low pack out again job
Thanks

Now Then..
Why do you keep bleeding the clutch?? Air in the clutch control won't make the clutch slip.
If you try to stall the tractor in both Hi and Lo of the Hi-Lo see which slips.. Has it been assembled correctly??

Had it split for the high low just bleeding it when I put it back together pack was rebuilt by jd mechanic it'll stall the tractor in both high and low it just feels like its slipping when high is engaged or when going the road when you flick it into high it feels like more of a delay once it's in its away but when taking off you need the clutch out a fraction more for it to move in high all hydraulics and steering are working fine

3650’s ate clutches, Salmon contracting at Trowbridge had some when they were current, I remember hearing the clutches slip every time they moved from standstill.

The clutch is perfect 9mm left on it I opened it up just to check you only notice it in 7th and 8th

Pressure plate is faulty

If the pressure plate was faulty would it not slip in low dual power as well. kicks in straight away in 5th and 6th and not bad in 7th it's only in 8th that you really notice it

I'm told the problem has to be in the high low pack anybody had this before
