Hello all been awhile since I’ve been on here, I’ve got caught up with life as I’m sure you guys know. I have a case 448 that makes a squealing noise when in high gear, it only does it when you move the tcv forward pretty quick. It also does it when I am plowing the garden in low gear and will not spin the tires. I hooked up a test gauge to the drain hole and tied her off to a tree to test the pressure at the relief valve, it relieves at or slightly above 2000psi in high gear. Could it be the tcv is out of adjustment? I’m lost at this point needing help.
