The transmission in my 2590 has been acting up. The tractor starts up fine and you go to let out of the clutch completely and it wants to kill the motor I put it in gear and it goes in all gears forward but you have to hold the clutch down half way or it will kill the engine when you try to disengage it completly . The tractor also will not go into reverse at all now. Where and what would yo u start to look at as the problem .. Thanks For any help

Our 1370 done this once, and the old case mechanic said to leave the gear shif in neutral and shift the power shift several times with the engine running. Worked for us.

This is a common area of discussion on this forum, most likely your transmission control valve has been contaminated by dirty transmission oil that has got by the filters, probably from plugged filters that should be serviced, causing pilot spool sticking, they must be removed and cleaned and reinstalled. get a print of the control valve so you know where they are located , remove the cap nut and screw a long machine screw in the threads provided in the spool, rinse the bore out, move the spool back and forth till it moves without binding and reinstall the spring and cap. there are 4 of them and all should be cleaned , do not mix any parts, put them back in the original bores.keep us informed as to how you are doing
