    I am changing the fluid in my T14 tranny and Dana 18 tcase and was wondering what weight they take. Also could someone tell me the low/high ratios in the 18 and if anyone knows what the T14 gears are. thanks

    nickmil In mothballs.

    The 18 transfer case has a 1:1 high range ratio and 2.46:1 low range ratio. Don't remember on the T-14, hopefully someone will chime in. I like plain old 85-90 in mine but our weather in the Pacific Northwest is pretty mild compared to other parts of the country. FSM shows 80w for winter and 90w for summer, GL-4. GL-5 will work great.
