MF 8150 transmission problem

[flatliner]

8150 is playing up again. I'm getting an intermittent transmission oil level light coming on even though the level is ok, and losing drive. The steering is also feels a bit gritty, and not getting any trailer brakes, and the flow of oil from the trailer brake bleed screw seems to be lower than usual, and also a soft brake pedal. All this happened out of the blue yesterday. Does it sound like filters, even though the filter light hasn't come on?

Cheers

Hyd pump? Dynadrive or power-shift? @masseybreaker

Hydraulics and dynashift working as long as the warning light is out. If it's on they don't work

If the tractor is warm when the light comes on it is the hyd pump getting worn and will need replacing. The filter will also be blocked and need replacing don't put old oil back in the transmission.

If you are sure everything works fine when the light is out then I'm guessing an electrical fault or maybe a faulty pressure switch

Left her ticking over for a couple of hours today, but got no warning light and drove ok, but brake pedal does feel softer than normal, and oil flow from trailer brake bleed screw seems less than normal, and can't get trailer brake to work. There's always been something about this tractor,where you need to bleed the trailer brake daily and if she hasnt been used in a while shes an absolute pig to get bled .

do the simple and cheap things first fit a new sensor
does the filter light work ?
hopefully its electrical if not start a list of possiblilities
charge pump
main pump
priority valve
orbitol unit
hopefully its not any of them good luck and report back
sound like your trailer brake slice is knackered also
