['63GENIII]

I took it for a test drive as soon as I put in the oil and was a little dissapointed. All of the gears seemed a little "notchy". No grinds, just not as smooth as before. 3rd gear was especially bad. It gave me the feeling that it could grind if I wasn't real deliberate in my shift - not forceful, just deliberate. It seemed as though it didn't want to go all the way into gear every time. Sometimes it was ok, more often though it wasn't. I didn't have time to figure it out though, I had to pick up the tractor (2500lbs) and trailer (2000lbs). I picked up the tractor, trailer and started towing them to my house which is through a bunch of hills. It isn't exactly the place where you want a slow shifting transmission. Still no grinding, just slow and notchy. I towed the combo down to the school the next day and noticed that it seemed to shift a little better when cold than warm. By days end, when towing the combo back to storage, it seemed to be shifting a little better... almost consistently. I am guessing that all the new parts need time to "mate" or break in? And maybe 3rd is the worst bc it has the new gear, syncro AND slider which need even more time to break in. One thing I did notice on the test run is that when on the freeway, Keeping up with traffic no longer requires spinning 3,200-3,300 rpm. The 396 was loping along at about 1,900-2,000 and seemed happy. Without a speedometer and just going off of the flow of traffic, it's hard to say but I think the TH400 that I had before was slipping real bad all the time. So much so that I thought it had a stall converter. I really like the 4500 so far and opening one up to make repairs isn't as difficult as I thought. I think this marks the end of my first build - unbuild thread. Thanks for reading! Chris
