Cat 955h 60A transmissoin oil

i have a cat 955h see:60A track loader that i just got running after it sat for probably 20 years. the machine started and ran great but at first the tracks had no movement but you could here the engine bog down when you moved the shifter. the converter oil gauge said it had great pressure. after like 10 minutes of shifting forward and reverse everything started working properly. it has a power shift transmission and the oil on the dip stick looks really thick. i want to change that oil. does any one know what type of oil this takes and how much of it? also is there converter oil and then also tranny oil? drains and fill locations for all this? any other recommendations for thing that i should look at before running this old ? Thank you in advance Jake

    You use the same as my L model, and here is the spec for most all Cat equipment. Starting on page 40 is the listing for 933 to 973 https://www.barloworld-equipment.com/media/1471478/c10513033.pdf I use 30W for trans, 10W hydraulics, 50W for finals

    Haven't been under the hood of the H model, and the torque converter should be part of the transmission. Here is where my locations are. Transmission and Differential are side by side under the plate in front of the seat. Final drive is a 3/4 drive pipe plug at the rear of the machine just inside from the track on each side Tried looking up your machine at CAT but I'm not seeing anything other then the serial number range

    Try here .... https://servicemanualpro.com/?page=Products&searchbox=60A Plug your full Serial Number in and find an Operation & Maintenance Manual on CD for around $40. My call would be HYDO SAE10W (ISO AW32) in hydraulics, TO4 SAE 30 in transmission, & TO-4 SAE 50 in finals, unless someone like Old Magnet comes along and says different.

    Sounds pretty straight up. Thanks for the help guys. Hopefully this fresh oil gets and transmission running smooth.
