You have the correct dip stick. The scavenge pump suction strainer is not a magnetic strainer. Take a look at the flow diagram on page 22B-30 Group 43 Page 1 in your Service Manual. The scavenge pump is a two section pump, 31 gpm scavenge and 21 gpm recirculation. Scavenge flow goes to transmission lubrication and on to the steering clutch compartment. Recirculation flow goes to the torque converter and the TC outlet relief valve and on to the magnetic strainer ahead of the transmission oil cooler.
3-4 gallons in the converter housing just means the scavenge/reciorculation pump is keeping up with whatever is being recirculated along with any leakage from the TC and possibly leakage from the engine. Doesn't mean your not getting leakage from the engine.

Thank OM, I believe you are correct as you can see from the picture it is leaking from behind the flywheel... On the engine side ...Clearly this should not be happening... Do you agree I need to remove the T/C and change out the seal behind the flywheel??? To me you are correct left long enough there could be way over the 5 gallons as it continues to drip... Water or excess in the engine could have damaged the seal....

I dont want to tear into it if you believe I have another problem... The scavenger pump I agree is working and keeping up with whatever is being dumped into the TC... But as you know it is now circulating into the transmission and the steering clutches... Engine oil as you know is not the same spec as transmission and steering clutches.... Besides that I need to drain the transmission fluid and get whatever contamination that has occurred....

Let me know what next steps you would do... Thanks OM...

What is the oil level in the engine reading? At rest the oil level should not be high enough to reach the crankshaft seal.

At rest the engine oil is above full on the dipstick. And when it is running it drops down about halfway down into the middle of the full add marker on the dipstick...FYI I have not started the tractor in a couple of days... Of course I am checking level at low idle...

That seems normal. A test would be to pressurize the engine oil system and check for leaks.

Not sure how to pressurize and don’t want to blow a head gasket or cause more problems...

From my end looking at the flywheel and seeing that drip behind the flywheel is of grave concern....

That oil draining down is excess from the center of the flywheel area, that oil looks contaminated with steel or worn material making it look gray. Did you pull the main hyd pump for the trans/strg clutches yet and check it? If the seal is bad in it that will draw the engine oil in, plus if the pump is badly worn that could be where the metal film or gray color is getting in the trans oil.

Also might try overfilling the engine oil level and seeing how much you get leaking past the flywheel and into a bucket under the TC housing drain in a day or so.

No I have not pulled that pump yet but will.... When Would be a good time to Drain the Transmission the spec shows 34 gallons. I want to drain it now what do you guys think? Thank you Rome and of Course OM...

I did find some bits of metal in the bottom of the TC. Not a lot but enough to know that something is wrong.... Oh fun days but the good thing here is I am not working out in a mud pit... I am working under a palm tree and it gets sun where it is 75 degrees and all my tools are right here.... If I take the main hydraulic pump out should that stop the metal grey material flow from stopping????

Regarding the metal bits.... I know that the starter pinion gear fractured when I took out the old starter I looked down in the hole and saw the gear fragments in there... They matched perfectly to the new gear that was on the old starter.... The previous owner had the starter rebuilt and when I talked to the guy that rebuilt it he said it needed a new gear.... I am thinking that the bits I found are from the starter still...

Some more info.....

That grey stuff could be from a failed rear crankshaft baffle/seal.
