I have a 335, with amplitorque. The IT manual shows me the oil check plugs on the right side of the transmission case. One is for checking the TA, and one is for the tranny. The manual shows me a large plug on top of the tranny, for adding 90 wt, to the tranny. It does not say where to fill the TA if needed. does the TA, and the transmission share the same oil sump? and the same oil?

I was successful, in filling my ampli torque chamber today! I removed the adjustment hole cover on the right side of the tranny case, and there was ample room to add oil, which I did, till it ran out of the check plug hole. NOW I would like to warn anyone, who removes the adjustment hole cover, to NOT take the center bolt , all the way out! You will lose the cross bar inside of the chamber, if you do! The cover has one 3/8 bolt in the center of it, that screws into a piece of bar stock, which spans the inside of the hole, to tighten the hole cover in place.

Hay you guys MAYDAY MAYDAY!!!
The ampli-torque is not a DRY unit. If it was you would not need any fluid in that compartment. That compartment MUST be filled first through the plug opening where you adjust the clutch pack. Up to the upper level plug on the right side. If only the rear end is filled it may take a long time for the compartment to fill and damage may be done to the clutch. Also if only the rear is filled it would eventually fill the front but then the the rear is going to be low.

You my friend, is the only one who answered my question. THANKS If I was silly enough to try and fill it with the transmission fill hole, I would be way overfull on the tranny, by the time enough got in there to spill over into the amplitorque chamber. I can see a cutaway view in the IT manual of both chambers and the oil level in those chambers are different!

There is a trough along the right side that the transmission gears throw oil into while driving the tractor. The oil runs forward in this trough to the ampli-torq compartment and slowly drains back into the transmission compartment through the bearings. When the correct amount of 80-90 oil is in the tractor, The level will be at both the check plugs on the right side. If you only see oil at one plug, you may have to drive further or wait longer to check it or if you can't get it up to both plugs at the same time it must be low on oil.

Minneapolis moline ampli-torque is not fluid operated. It is basically a dry clutch pack

Ampli-torque is in 80w oil. Torq cavity filled from same filler. Has a bung to check for both compartments. Reason for decal on dash to warm in high range.

Thanks Molinegb, I have no decal on the dash, and this is good to know! Also this is a utility tractor, with a missing serial number plate on the right side of transmission, but does have the two small levers under the seat for draft control.

Should actually be called an Ampli-torque. T / A is another brand. Remember decals on M5 and newer.
