John Deere 6600 low transmission pressure

Hi all, hoping someone might be able to help. I have a John Deere 6600, a few months ago the transmission light started coming on after a while of hard driving on the road. Any time it was hot and I hit the brakes the light would come on. It would not take reverse when the light was on, it would eventually reverse after I clutched it a few times and gave it some throttle, the light would then go out. I brought it to my fitter and after pressure testing he checked the brakes, they were ok but changed them anyways. He also checked axle bearings and they were ok. He also pulled the power quad apart and all was good no wear and nothing needed replacing except the gaskets. Long story short after a new transmission pump, new oil/filters and 4wd seals, the problem seemed to be solved for a few months until today. Light is back on and loosing drive after less than an hours road work.
Has anyone experienced similar problems? as I don’t know where to start again. Many thanks in advance 👍

Mine will loose pressure at idle after a hot days work baling usually, traced it down to the mfwd circuit somewhere have changed the seals in the clutch pack, didn't really cure it, have also changed the 'o' rings on the solenoid valve to see if thats where it is, the transmission pump also does the pto so it could loose pressure there somewhere.

Thanks for the replies, it doesn’t seem to make any difference if 4wd is on or off on mine, the light will still come on at idle wether 4wd is on or off 🙈
