I have been searching the internet and this question for me seems to be all over the place. I have a Borg Warner T5 Model #1352-145 Original application 1985, 1986 S10 Engine 2.5 L4, 2.8 V6 and it will be mated to my 235.

Today something was not right when I changed the drive and driven gear so I took it to a professional in town. Not to get off topic but he been in town a long time and has a few cool COEs.

Well he fixed my boo boo and told me that I needed to put non synthetic regular 10-30 motor oil because of the desert climate in Las Vegas.

Does this sound right the book says on thing and I am totally confused on what to put into it. What are your thoughts?
