Lifted the shift tower off to investigate why this T84 does not like to go into 1st and reverse and discovered it had very little gear oil and what it did have was milky. Lucky the gears were rust-free. Note that I'm not saying that was related to the shift issue, I'm only focusing on the moisture issue here. I have no desire to pull the transmission. Anyone have ideas to get it dried out? I was thinking perhaps alcohol to bond with the water, flush with gasoline or just waiting for a warm sunny day, take the tower off again and let the sun shine in.
Thanks, Doug

Re: Drying out a T84
I'd stay away from gasoline for the KABOOM! factor alone...
Can you drain it and try flushing with something like diesel or kerosene rather than alcohol or gas? Since the trans is still in the jeep, if you fill it up, it will probably start leaking out the bellhousing but if you can use one of those I suggested and then let the motor idle (you'll have the fluid being thrown all over, so you need something to prevent that). First, take the transfer case OUT of gear after chocking the wheels and setting the handbrake. You won't need the shift cane, but at least place the tower and two bolts in place and start up the jeep and let it run for a couple minutes.
Remove the tower again and see what remains; dirty fluid or relatively clean? Drain it and repeat and check the drained fluid again. If it seems you have gotten rid of not only the water but the combo-fluid of gear oil and H20. Refill with clean gear oil and you should be OK.
The remaining moisture will evaporate on a long, hot drive (hour) but you need to figure out how that got in there and make sure that won't happen again. I'm wondering if the monsoons we've been having could somehow of allowed water to seep down the shift cane into the T84?

Re: Drying out a T84
Doh, diesel or kerosene of course. When did my common sense leave the building. Thanks Chuck. As to how water got there, this was used heavily for about 15 years on a large high fence hunting ranch. I expect it had a few stream crossings during that duty. I'm sure it did not happen during the couple months I've had it. It's been covered or in the garage the entire time. If things go to plan you will see this at Camp Plymouth next month. I assume you'll be there. It would just be wrong if you weren't.
Cheers, Doug

Yup...I'm in space 274 and will be selling more of the stuff I have collected the past 15 years or so. Hoping for good weather but this year? Who knows!
