T450 ISO tilt acting up

[billyb]

T450 joystick changeable controls. Bucket tilt backwards acts up. Bucket moves quickly and kicks out loader controls. When tilting bucket back and let go of joystick, the bucket will sometimes keep tilting back as far as it can go. When this happens all loader controls are locked out but drives still work. Wondering if I should be looking at joystick or solenoids wherever they are??

Had exactly same issue until loader controls quit completely. Code said tilt actuator not in neutral. Installed new tilt actuator on control valve and no change. Checked all wiring and connectors. Machine had 500 hrs. 2019 T450 and no Warranty because over 24 months old. Took it to Dealer for diagnosis. After about 6 weeks and $3500 Canadian they changed the ECM that is under the cab on the LH side inside the frame. It was $1300.oo Canadian. I believe it also had to be programmed by the Dealer. If need be I can look up the part number for the part
