Hello, I’m hoping someone can shed some light on an issue I have encountered. I recently found a 1981 Case 2390 and have been going through and getting all fluids/filters changed and up to date. The tractor sat for the last 6 years, and had the transmission rebuilt about 100 hours prior to when it was last used.
I pulled the RPS34 and cleaned it, as well as the spools because I could tell a couple of them were sticking. Got it put back together and all gears/ranges work great except for PS2 (power shift 2). When moving from PS1 to PS2 or from PS3 to PS2, the engine immediately lugs down, and it doesn’t matter what range the tractor is in. I have an idea of what the issue may be, but wanted to inquire here first. Thank you for the help.
