D6B 44A transmission overheating

what else apart from the transmission does the oil do Im guessing steering servos or something if its a ag crawler I think they might use the oil for the implements but dont know
It sounds like something is pumping thru a relief valve if its get real hot

There is a turbo on a 44A? I would expect it to get quite warm under the constant load conditions of ag use with the extra power going through it. I'm not sure if the steering booster is fed by the transmission oil, this could cause the oil to warm up if he steering clutches need adjusting.

D6B 44A6857-UP were high hp, 44A1-6856 offered a turbo as a “high-altitude normalization option”. The steering booster has a separate oil reservoir and steering would not cause the transmission to overheat.
The Operation and Maintenance Instructions book lists the transmission oil as 10½ gallons Series 3 30wt. engine oil. The wrong viscosity oil could cause a heating problem but not to the extreme described. I do not like to use Transmission and Drive Train Oil in a Direct Drive transmission, but that that is just my opinion. Series 3 oil is still available in my area and that is what I use.
The cause for the transmission to overheat would most likely be bearing failure, but there would be additional symptoms.
I wonder if the operator is actually checking the transmission oil dipstick or if he could be checking the oil-clutch dipstick. If the clutch needed adjusting and was slipping even slightly, the clutch oil would rapidly overheat.
I suggest you get an Operation and Maintenance Instructions book for this tractor; they are sometimes available on ebay.

The constant load of pulling an implement is very different from dozer or even scraper work. The transmission and final drives will get hot a lot faster and stay hot all day long pulling implements. We hooked our 9U to a heavy disk to chop some scrub and brush a few years ago and quickly discovered the cooling system was not up to snuff! Had had no problems while using the dozer before that!

There are any number of miracle fluids that claim to reduce friction and heat in drive train applications, but I agree with seiscat, the first thing I would do is to use a light gear lube vs a powershift transmission (TDTO) fluid or even a motor oil. Something spec-ed for over the road truck transmissions like Road Ranger etc should be about the best possible choice for good lubricity and long life.

Thanks for the replies. I will "borrow" my tractor back, and most likely run lit through my own shop and see if I can spot the issue. Who knows, maybe there isn't even a problem. I've had truck drivers and equipment operators that would freak out over sights and sounds they "think" they heard.... Kind of like being hypochondriacs. JM

Hey JuiceMan,

I think since there wasn't an enclosed dust free cab with AC and a Stereo, that the tractor has lots of problems... Better shut her down... And get a new one with Auto Steer and GPS. And deliver a Mocha for their Break Time Too...hahaha

Correct. the steering clutch booster has its own reservoir, how hot is hot? If the transmission has the correct oil in it and there is no bearing whine, there is probably nothing wrong with it.
