Tm 150 restoration

[Farmer mk1]

Evening,
Have a tm150 and it’s a real tidy tractor body wise and it’s not done a days hard work. It’s sat on a machine and just been ran at 1200rpm for 7000 hours.
Some times when changing gear from c2 to c3 it has a delay then jumps into gear. And it has a delay but no where near as bad when coming down the gearbox. It’s not slipping so don’t think it has an internal leak but it sometimes tries to throw you out the back window it is that violent.
Another problem is I think the pump is running slightly on swash as it is getting hot on the back end. When started in the morning it is really quiet but once it gets abit warmer you can hear the pump working slightly and if driving for a while at 2k rpm on the road and you go to use the spool it is like it has siezed up and won’t go into float so I think it’s getting hot and then nipping the spool.
anyone any ideas or if it’s going to be a pump replacement needed or is it the compensator valve sticking open slightly?

Sounds pretty normal for a tm to be honest, gearbox calibration and adjust the spool valve cable when it's hot. If it heats up very quick might be something wrong but I regularly had to adjust spool cables before lunch when mowing with a 155

Our other tm doesn’t get hot on the back end like this one does at just driving. It sounds like the pump is slightly on swash and boiling the oil. Does anyone know what clutch pack combinations are to go through the gears in c range?

A new accumulator bottle will most likely sort out the jumpy gear change
