Cat 977L transmission oil and hydraulic oil capacity and type

Greetings,

I can't seem to find the information for 977L oil capacity for hydraulic and transmission. Can someone please provide these specs? I do see that Cat calls for HYDO in the hydraulic system. Should I run straight SAE 30 in the transmission or TDTO? Thanks in advance!

Use TDTO in the transmission.
I don't know the answer to your question about the hydraulic system but that answer and more can be found in the operator's guide for your 977L.
I found this one on eBay:

Look on the back pages of your parts book under specifications and you will find capacities for lube systems, cooling, hydraulic and fuel.
You don't need to use HYDO or TDTO unless Cat has it on sale.
Look under the dash for the info plate with serial number.
