Also looking to change my transmission fluid and filter. Looking at my book it gives lubricant viscosities for Ambient Temperatures. The two I’m looking at are SAE 30 min. 32 max 94 degrees. SAE 50 min 50 max 122. Here in Arkansas we get to 100 but I don’t know i would be using this open cab dozer at 100 degrees. So it looks like my pick is between 30 and 50 weight. Looking more like 50 to me. Have anybody had any experience with NAPA 50 weight or should I stick with CAT. Going change the transmission oil out next week. Probably not talking but 150.00 difference for total purchase but definitely don’t want to go cheap if it’s going to wear parts faster
