Hey I just bought our first backhoe an old 1994 Case 590 SK 4x4 and it runs great but I'm getting a loud noise coming from the transmission but only in 3rd and 4th gear when I'm in 1st and 2nd its smooth has plenty of power but soon as you shift to 3rd and get up to speed it makes a grinding howling sound also dose it with the outriggers out with the wheels off the air in drive forward and reverse.I checked the fluid its clean a little overfilled about 1 inch over from the full line. Any one know what this might be? It has 7500 hours on it
