Ford 545 Backhoe Shuttle Shift Trouble

[richgwilson]

First post to the forum, tried searching for a while and I know this is a popular topic but I don t often see a resolution posted about it.

My somewhat new to me Ford 545 backhoe with the 4 speed shuttle shift is giving me some trouble that my experience makes me think shouldn t require splitting the tractor. It s when it warms up it will stop going forward after a while. But when it stops going forward, it will go backward for a while. Then it will give up that direction but be willing to go forward again and so on. This really seems more like a clog or something but I m new to these and thought someone here may be able to point me in the right direction quickly. Thank you in advance for any recommendations and help.

Worth mentioning I ve adjusted nothing yet. Planning to change the hydraulic filter on the side of the trans but it doesn t look too old. Could it be the wrong fluid causes this type of issue? I believe it s full of tractor supply s universal since the torque converter shares its tank with the loader/backhoe iirc. And the loader/backhoe tank in the front of the tractor is definitely full of that.

The transmission and hydraulic systems do not share oil. A new filter and fresh oil are your first steps.

There is a pressure test port at the bottom front of the transmission just underneath a metal plate with 4
bolts. Find a 300-PSI gauge with a 1/8" NPT fitting and monitor the pressures in neutral, forward, and
reverse, both when it's driving and when it's not. Post back with your results.
