School me on ampli-torc

So the neighbor brought over his 4 star cause low didn’t work in the ampli-torc. Found this out when he bought it 5 years ago. So split it removed all needed to get at the ampli-torc. When I pulled out the planetary the cam cage stayed in the tractor. When I looked in I then noticed why low didn’t work. None of the rollers and springs were in there! You could tell someone was in there a long time ago. Fought to get the cam cage out of the housing. Got it all cleaned up and new parts ordered. Was told to check the hub condition. Looked good for what I was told to look for. I should mention that this is my first torc in a moline so I’m learning. Got the new parts and put together with the aid of the service manual and a good moline friend of mine. Spun the over running clutch and felt good. Locked up when spun the other direction. Assemble tractor all back together and test drive. I read somewhere that the transmission needs to warm up some. Is this true? I did put a universal trans/hydraulic oil in it. Didn’t drive much as the tractor ran out of gas!! When I did run it I didn’t noticed much speed change when I pulled the torc lever back. With the lever back I did step the brakes for a moment and the engine really bogged down in RPM. Just here trying to get a feel of the rebuild and testing of this tractor. Thanks for looking.
 
Sounds to me like you did everything right, including the oil. Go get some gas so you can test it further. The warm up the oil deal is to allow the oil to thin out a little. That accomplishes 2 things, first to see to it that things get thoroughly lubricated and second, cut down on the friction between the high range clutch discs. You may not note a lot of speed change when the torque is disengaged unless you have some sort of pull load on the tractor. Note that the same is true on the PTO clutch. There is no brake on that clutch and if you insist on trying to stop that PTO by reefing on the lever, you will do damage. It's a Minni, shut the tractor off, hook up your PTO implement and then proceed.

Got to test drive and it all works good. I noticed the change going up hill. Not so much on flat until I’d hit the brake a little. Thanks for you post curt!
 
But my dads 445, the PTO wouldn't stop turning with the corn picker being pulled,so that's was normal? I was to young to run the picker, but plowed with it!

Ampli Torc shouldn't have anything to do with the PTO.
 
Some PTO s disengaged will run an empty manure spreader. But not a piece of equipment like a picker. The plates in the clutch must really be warped.
