Okay guys, update. Got the PTO issue resolved, and now I'm ready to look at the low gear issue.
Here's what I know: the entire low range will not engage at all. The high range will engage. The PTO will run in either low or high range.
BTW, F350-2, I want to be sure we're talking about the same area. I'm talking about the open area that extends from just behind the engine to the back of the PTO area, and encompasses the gears, rear end, and PTO stuff. I dunno what you consider a lot of oil, but it drained over 11 gallons for sure!
So, any gurus out there that can tell me why I might not be getting the tractor into low range?
I found the password for my original F350 account. 485didriver, I believe we're talking about the same thing. I may have understated the amount of fluid. It's been a while since I changed mine. On my 485 the transmission takes gear oil and the "rearend/pto" area take hydraulic fluid. Two seperate systems.
