Had a indicator light come on in my 755c series 2 machine this afternoon. It’s the transmission oil pressure indicator light. Had been operating the machine for a half hour or so and received a phone call so went to idle. When finished with the call noticed the light on. When I would rev up the machine it would go away but return on when at idle. Parked it for the day planning on replacing filter in morning. When I looked in manual it describes it further as “transmission hydrualic replenishing oil pressure indicator” call dealer it says. Dealer says it might have been the colder temp today( 25ish) but I had been operating the machine for half hour or so. Any ideas where to start besides filter? I have had a couple hydrualic hose failures lately so have pretty much replaced the oil in the last 50 hours. I did notice right before the light came on in a hard push it kinda stuttered a bit but i assumed it was from spinning on the frozen ground but maybe it wasn’t. Thanks for any help

Serial number? Picture of the light in question?

Do you have pressure gauges? Charge pressure needs to be checked to see if there is in fact a pressure issue or a sensor issue.
Checked charge pressure. About 45 degrees out today let it run for 20 minutes. 245-250psi. Light stays on at idle and initially goes out when rev it up but then light comes back. It actually flashes on/off super fast. Pressure about 250 at higher rpms. Going to replace filter in morning and check again.

Minimum pressure is supposed to be 232 psi. Yes, change your filter first, if that does not resolve your light issue then it sounds like a pressure switch is going wonky.
