Gents i purchased a 1988 580K Series #2 backhoe a couple years ago and it was having shifting issues. the symptoms were and are the forward/Revers shuttle system takes a while to engage? after it engages it works fine (while its in use) but after being parked for a while (a day or 2) it goes back to "won't shift"? I changed the Hy-Trans fluid and filter yesterday to prepare for a summer season of digging and now it won't shift at all in forward/reverse. does anyone know how +to trouble shoot the shuttle system on this rig? is there a Internal Shuttle Valve or Pump in this tranny that is failing? on this Unit the complete tranny assembly is attached to the rear-end. any help will be much appreciated.

Welcome to HEF @Bakobob Most problems (98%) regarding a lack of drive with a power shuttle can only be repaired by removal & overhaul. You will need a service manual - but be warned there are many things that can go wrong during such a repair. Do a search here & you will find a great deal of information about this type of problem. Be certain your oil level is at the correct level & you are checking it with the engine idling.
You said your backhoe is a 580K series 2 where is your four speed shifter located is it in the floor in front of the right hand console or in the right hand console itself?
The Shifter is in the right hand console itself. Well here is an update. I have not changed the tranny oil since i purchased it so I drained the tranny oil and the viscosity appeared to be that of engine oil! I put in Hy-Trans oil (the Case recommended oil) and its been working perfect!!!!! yes I changed the filter too. so i guess its worth the cost to change all the fluids after you purchase heavy equipment and in my case I got a good rig cheap due to wrong oil!! YEAH. thank you all for your help!! Bakobob
Wow, you are one lucky son of a gun.
Good deal glad you got it going. I did work on one 580K phase III that someone put gear oil in needless to say it didn't shift worth a crap.
