2002 JCB-214 Transmission light and buzzer when accelerating

[JCB-214-2002]

I've read a few threads on this topic in the forums but my symptoms dont seem to be the same. A few never posted the final outcome.

Backhoe transmission has been working fine for the last 400 hours. Since I purchased it.
Now when I accelerate (Primarily in 3 and 4th gear on a grade) the transmission lights illuminate and I get a buzzer. If i let off the accelerator, both stop. If I downshift to 2nd gear it stops.

It appears to happen mainly when I am in 3-4 gear and start off with heavy engine load. It also happens when going up an incline where I need to press the accelerator harder. Again, laying off the accelerator and it will stop buzzing, lights go out.

When the light and buzzer are on, if I press the accelerator harder, the machine does speed up even though it is buzzing at me.

I changed the trans oil and filter today. I did not see a strainer when I pulled the oval plate on the bottom to drain the oil.
Still same symptoms

Anyone have a like experience or know where I can check next?

Taking it to a dealership is too expensive for me right now.

Thanks

There should be two lights for the trans. One is for " oil pressure" ( it has two arrows pointing to the trans". The other is for " oil Temp", which one is it or do they both come on?

It cleared up today, no warning light or buzzer. Must have been something with the trans oil or filter.
I'll let you know if it returns.

Thanks for the response.
