Decided it is time to change the transmission
oil. Checked year stamp on transmission and it is 87 so by all means should be World Class T5. Checked
oil and it seems to be too thick to be ATF, so seems to be gear
oil. Been asking people and looking on line and have been getting conflicting information in regards to either using gear oil or ATF Dexron III auto transmission oil.
I am leaning towards the thinner ATF Dexron III with Nulon G70 as additive as I can't find penrite lubrizol additive any where. What is every one s thoughts on this.
