Customer Question
I have a 1978...

I have a 1978 JD backhoe. I can't determine if the fluid dipstick and port under the seat is for Hydrolic fluid or transmission fluid. Or are the both the same on this model?

Mechanic's Assistant: What is the complete model and serial number of your machine?

JD500CD Serial is 278828

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

I bought a TM -1038 online and several pages are missing.

Mechanic's Assistant: Anything else you want the Agriculture Mechanic to know before I connect you?

I just need to know what fluid to use and where they go.

On your model, the transmission is the reservoir for the hydraulics, so the one dipstick and fill port are for both.

Good. What type of engine oil?
And Coolant do I use.
Mechanic: Curtis B., Technician replied 2 years ago

15W40 diesel oil for the engine, and use standard 50/50 antifreeze, Peak or Prestone will work.
