Default Re: T-5 transmission

Been selling rebuilt S 10 T-5 transmissions for 20+ years and the rebuilder I use puts a tag on the trans recommending Dexron III. I've also used the GM recommended fluid available thru GM parts. Problem with regular gear oil is if you live in an area where it gets cold the gear oil can thicken and make the trans shift hard.
