You inspected it; he said it looked great...whatever; throw it in the trash can. They're too hard to change. If you take the trans apart completely, check the governor support. Unbolt it from the case and check everything about it. If you want to study that governor, take it apart right next to a known good one and I think you'll see a difference. Might just be a stuck governor valve. I wonder if A&A still has governor PN 22204-58 to shift automatically at 6200 wot.
