2002 TC 40 transmission heat

[5030]

Put the correct NH fluid in it. That's not the right stuff.

Buying cheap fluid isn't always the answer. I happen tp use Rotella HD in one of my gear drive Kubota's but I'd never use it in a hydro.

After using the tractor for a long period of time the transmission gets extremely hot. its a 12/12 shuttle shift.
what could be causing this?

It's normal for transmission to get hot because the oil in the transmission gets hot from friction. The transmission is not 100% efficient so the losses due to friction and windage show up as heat which raises the fluid temperature which in turn raises the transmission case temperature.

What are you using the tractor for these long periods?

last week i disk for a couple hours. but most of the time I'm mowing.

what would you call the high range for normal heat?

this is not a hydro.

Don't matter really. Cheap fluid lacks the additive package that quality fluid does. Neither of mine are hydro's either.

I had the transmission case get hot to the touch when I was using my 7 ft drum mower to cut hay at 90°F. I'd guess it was about 115-120 °F.

Can you find a infrared heat gun to get a accurate measurement of the transmission case? What’s the outdoor air temperature been while you mow ?
What gear and engine rpm are you using while pulling implements? Maybe try a lower gear and lower rpm. If the transmission housing is reading 170* fluid is maybe 180* that in my opinion is about max . Your implement lift cylinder doesn’t have a internal leak ?

this is not a hydro.

But it does have a wet clutch for the PTO and wet brakes. Both are very expensive to replace vs buying the $100 for 5gal correct oil.

Has anyone had a problem using Shell Rotella HD? I thought that was the good stuff.
